Drone Technology at NJDOT

Posted on

NJDOT’s Unmanned Aerial Systems program in the Bureau of Aeronautics is demonstrating how the adoption of drone technology can serve NJDOT’s goals to increase safety, increase efficiency, save time, and save money. Drones are replacing boots on the ground, increasing accuracy, speeding up data collection, and providing access to hard-to-reach locations for divisions throughout the Department.

Drone Program Reaches New Heights, Seeks to Go Higher

Posted on

In May 2016 the New Jersey Department of Transportation’s Division of Multimodal Services established the Unmanned Aircraft Systems (UAS) Program as a unit within the Bureau of Aeronautics.  The UAS program coordinator position was created within the Bureau of Aeronautics to lead NJDOT’s UAS initiatives. This position was established to provide leadership, guidance, and coordination for division flight operations. Other responsibilities of the position include ensuring compliance with state and federal aviation regulations, coordinating FAA airspace waivers and authorizations, assisting RFP efforts when contracting consultants, and informing NJDOT of public perception and liability.

In standing up the program, a survey was distributed to all other NJDOT Divisions to identify potential missions that could benefit from the integration of UAS. The 38 survey responses were analyzed and condensed into common mission categories such as structural inspections and construction project management. The missions were also evaluated to determine whether the use case had the potential to improve safety, increase efficiency, save time and save money for their routine operations. A suitable mission profile was developed and risk analysis conducted to create pilot projects for testing.

An early NJDOT study revealed the cost-effectiveness of high mast light pole inspections

UAS brings new tools forward for 3-D “Reality Modeling” with photogrammetry.

Initially, pilot project flights were conducted in support of structural evaluations, construction project management, traffic management, and watershed evaluations.   Valuable lessons were garnered from these initial pilot projects.  For example, a study of the benefits of using UAS for high-mast light pole inspections (HMLP) was shared with FHWA and a topic covered in NJDOT’s presentation at an invite-only national peer exchange held in Washington DC by the FHWA in 2018.

NJDOT’s UAS Coordinator, Glenn Stott, who had previously organized and hosted an NJDOT Peer Exchange on UAS, was invited to participate in the national peer exchange.  HMLP inspections, Stott observed, could be performed more quickly and less expensively than by traditional means. Cost savings include lost productivity due to the traveling public experiencing congestion issues. One advantage of UAS inspections is that they do not require shutting down a travel lane for a bucket truck to occupy. Furthermore, a UAS inspection only requires a crew of three to complete an inspection: two controllers: one pilot and one engineer, each with a camera and screen, and a third visual observer to monitor the site. Using this method, NJDOT was able to complete six or seven inspections per day compared with one or two using traditional methods, contributing to “significant” cost savings.

Going forward under EDC-5, the goal of the NJDOT UAS Program is the institutionalization of UAS technology and its integration throughout NJDOT operations. NJDOT hopes to leverage recently awarded STIC incentive funding to remove barriers in equipment and training toward advancing several potential use cases, including:

  • Survey Rendering of 3D Models. 3D modelling is a valuable tool that saves time and money by cutting person-hours and eliminating rework for transportation projects. 3D modeling of bridge decks and infrastructure is becoming a cost-effective inspection method for evaluating bridge decks to detect delamination in concrete. Using the right UAS technology, 3D modeling can rapidly determine the volume of stockpiles with a high degree of accuracy. Georgia DOT reports that that select UAS equipment can match GPS and LIDAR survey equipment and found the UAS reported volumes were within 1 percent of the traditional methods.
  • Watershed Resiliency. In March of 2018 NJDOT conducted several UAS photography missions along Routes 80 and 23 to support a Watershed Resiliency Analysis. Traditional photos were taken, but a thermal imaging capability would allow the NJDOT to more accurately determine the extent of flooding along our state highways. Thermal imaging overlays can more accurately define the extent of highway runoff and flooding issues. Thermal imaging is a better tool to detect water through the tall grass in flooded areas. Minnesota DOT has researched this use case and the NJDOT would like to expand on this research.

    Field tours demonstrate UAS capabilities to staff and partnering organizations.

  • Bat Counts Under Bridges. North Carolina is using infrared thermography to conduct counts on bat populations under bridges. New Federal regulations require state DOT’s to ensure they do not disturb a protected species while conducting inspections. The NJDOT Division of Environmental Resources has requested UAS assistance in conducting bat counts under bridges because they live in high and dark areas. A thermal imaging camera mounted on a UAS will confirm the presence of bats and should allow the counting of individual bats in near total darkness by detecting their body heat.
  • Thermal Inspections of Concrete Bridge Decks. Infrared thermography of bridge decks is becoming a valuable and cost-effective inspection method for evaluating bridge decks to detect delamination in concrete. The delamination photos can be rendered by addition of higher-end gaming computers into a 3D model that can be used to determine the exact location of each delamination.
  • Large Potholes and Longitudinal Joint Separations. The efficient identification of large potholes and longitudinal joints would require autonomous UAS that can be programmed to safely fly over long distances. Current regulations require small UAS to fly within the line of sight of the operator which makes this use case currently very inefficient and not cost-effective.
  • Thermal Imaging for Paving Project Management. DelDOT is examining the use of UAS to detect significant thermal anomalies during the laying of new asphalt. The UAS would take standard photographs and thermal photos of the same area. The photos would then be compared to detect potential quality issues in the new pavement. Sets of thermal and visual photos can be rendered through higher end gaming computers into a 3D model that can be used to generate a guide sheet to make it easier for work crews quickly find each problem area at the work site.
  • Construction Project Management. Several on-site inspectors, resident engineers, and traffic engineers have commented that the tiny UAS screen located on the UAS controller is difficult for a field team to view. A larger monitor mounted in the rear of the UAS Program vehicle can allow supervisors, upper management, and other non-participants to safely view UAS output in real time without interfering with the movement of the UAS crew.

Three years after its establishment, New Jersey’s UAS Program, continues to reach new heights as it discovers how it can effectively work with NJDOT’s divisions and bureaus to improve safety, increase efficiency, save time and save money in routine operations.  The UAS program challenges both the agency’s leaders and staff to adapt to new technologies, seek the training to develop new skills, and find new ways to collaborate to advance innovations in its transportation operations.

Connected Vehicles Program Pilot Testing of Technology for Safety Service Patrol Workers Continues

Posted on

The rise of crowdsourced navigation applications and connected vehicle applications provide new opportunities to relay road service safety information to the motoring public.  NJDOT has initiated a Connected Vehicle: Road Service Safety Message pilot study that evaluates the effectiveness of using connected vehicle technology to alert the motoring public to the presence of safety service workers at an incident site. NJDOT is piloting the use of a Beacon Hazard Lights technology to alert drivers to the presence of workers when safety service vehicles turn on their hazard lights. The piloting of the technology has received the support of the NJ State Innovation Council (NJ STIC) and a STIC Incentive Funding grant of $39,600 awarded by FHWA.

The primary objective behind the initiative is to inform the public of the presence of Safety Service Patrol (SSP) personnel thru various services and applications that share real-time traffic and roadway information once they have responded to an incident or to help a motorist.  A short demonstration video of how a technology-equipped NJDOT safety service vehicle interfaces with crowdsourcing platforms in the field can be accessed here.

Periodic interim reports for the pilot study are being prepared to evaluate the technology’s application during the STIC grant period. Previously, NJDOT and New Jersey Institute of Technology (NJIT) personnel conducted a field evaluation of the technology following the device-equipped SSP vehicle then subsequently maintained a data log of the device’s activity in the field and through mobile and web-based interfaces.  In continuation of this effort, the NJIT team proceeded with a similar analysis by studying the correlation between the data recorded via the device log and the crowdsourced navigation applications web-based interface. In addition, the radio logs maintained by the Safety Service Patrol were used to further support this evaluation effort.

 

Local Safety Peer Exchanges: Summary Report

Posted on

NJDOT, FHWA and NJDOT held a series of three Local Safety Peer Exchange events for municipal and county representatives to share best practices in addressing traffic safety.  These full-day events brought together representatives of NJDOT, FHWA, counties, municipalities, and Metropolitan Planning Organizations (MPOs) to discuss project prioritization, substantive safety, implementation of FHWA safety countermeasures, and use of a systemic safety approach.

The Local Safety Peer Exchanges Summary Report provides an overview of the event proceedings, including the presentations, workshop activities and key observations from the Local Safety Peer Exchanges held in December 2017, June 2018, and March 2019.

The Local Safety Peer Exchanges were funded, in part, though the use of a State Transportation Incentive Funding (STIC) grant.  The Local Safety Peer Exchange events are well-aligned with the FHWA Technology Innovation Deployment Program (TIDP) goal: “Develop and deploy new tools and techniques and practices to accelerate the adoption of innovation in all aspects of highway transportation.”  The focus of the Local Safety Peer Exchanges is also consistent with two of the FHWA's Every Day Counts (EDC-4) Innovative Initiatives: Safe Transportation for Every Person (STEP) which supports the use of cost-effective countermeasures with known safety benefits to address locations of fatal pedestrian crashes; and Data-Driven Safety Analysis (DDSA) that uses crash and roadway data to reliably determine the safety performance of projects.

 

 

On December 6, 2017 municipal and county representatives gathered to discuss best practices to address traffic safety. Topics discussed included NJ safety performance targets, use of Safety Voyager, substantive vs. nominal approaches to design, systemic vs. hot spot approaches to safety, and discussion of FHWA safety countermeasures.

The summary report provides documentation of the agenda, presentations, highlighted tools and model practices, and workshop activities for each of the Local Safety Peer Exchange events, including the December 2017 event.

Purchase and Evaluate the Use of Tablets for Construction and Work Zone Inspection

Posted on

In FY2017, the NJ STIC recommended that a STIC Incentive Funding grant be used for the purchase and the piloting of the use of the tablets for construction and work zone inspections.

Once acquired, the use of tablets were found to expedite as-built review reporting. For example, comments between team members were easier to share and compile and As-Built review reports, checklists and other supporting documents were no longer printed prior to the review. The reports and checklists could be completed electronically at the field office during the review as the information was collected.  A list of findings could be created during the review and shared electronically with the resident engineer (RE) and the review team.  Guides and manuals could also be shared with the RE on the tablets during the As-Built review to answer any questions.

Several benefits were evident from the use of the tablets in construction and work zone inspections:

  • Improved communications within a team in sharing or demonstrating a design idea such as sketches, field changes, request for information, etc.
  • Improved efficiency in keeping field records, particularly through the use of the camera’s function for capturing field videos and pictures.
  • More productive meetings as participants had the ability to quickly reference contract documents, plans or emails (Ex. progress construction meetings with contractor, Project Manager/Designer, and utilities.)

Some other lessons were noted in piloting the use of the tablets:

  • It is important to keep the battery fully charged; the battery life was found to last up to two hours with extensive use.
  • For practical use on site, the use of a stylus pen makes it much easier to use.
  • The tablet keyboard will be easier to use if a mouse device is available.
  • It is essential to have and maintain the remote internet access connection to enjoy the benefits of the field use of tablets.

Advancing Use of Mobile Devices in Administration and Oversight of Local Public Agencies Program

Posted on

By adopting a paperless process for delivering construction administration documents, practitioners can save time and resources while improving the process of managing construction documents. New Jersey’s State Innovative Council recommended that a STIC Incentive Funding Grant be awarded to NJDOT to advance the use of mobile devices in the administration and oversight of its Local Aid Program.  The NJDOT received a STIC Incentive Funding Grant of $21,464 in FY2015.

The STIC grant funded the acquisition of tablets for use in two areas: application ratings and construction inspection.  The primary benefits of the transition to tablets were expected to come from improved staff efficiency through a reduction in the preparation time prior to field visits and an elimination of the need to manually transfer data collected on paper in the field.

NJDOT’S Division of Local Aid was able to use the funding to acquire 14 tablets and Mi-fi “hotspot” cards to ensure field network connectivity.  NJDOT’s IT department was engaged to coordinate the procurement process to the purchase the tablets for Local Aid staff and install cellular connection, VPN Access, security software, licensing. Electronic Field Inspection reports were designed, developed and tested in accordance with the Division’s Policy and Procedure for Construction Inspection.  District training was delivered for the use of tablets for construction inspections of federal projects. The tablets were distributed to the 4 Local Aid districts and are in use.

New Jersey Pilots Connected Vehicles Program to Protect Safety Service Patrol Staff

Posted on

Each day New Jersey’s safety service patrol (SSP) workers put their own safety at risk to assist motorists in need and to assist other first responders. In addition to warning other motorists about recent traffic incidents, they remove disabled vehicles, provide gasoline, and perform vehicle repairs. Safety service patrol workers use temporary signage, traffic cones, flares, and portable variable message signs (PVMS), existing overhead message signs, the NJ511 phone and website systems as well as the SafeTrip application to warn motorists about their presence.

Unfortunately, collisions involving safety service patrol workers still occur. Cars often travel at excessive speeds near staff who work on the scene of such collisions. In 2015, the Federal Highway Administration (FHWA) reports that a work zone crash occurred once every 5.4 minutes in the United States. The impact of crashes can be catastrophic. Every day 70 work zone crashes occurred that resulted in at least one injury, while every week 12 work zone crashes occurred that resulted in at least one fatality. The NJDOT’s continued efforts to reduce work zone fatalities since the 1990s has resulted in one of the lowest rates in the nation. Despite this, at least one service worker has died in a New Jersey work zone each year since 2007. In 2016 seven fatal crashes occurred in New Jersey work zones, including the death of one service worker.

The automobile manufacturing industry is in the technology development phase of putting connected and automated systems fully in place.  Once deployed, first responders and/or their response vehicles would be detected by these systems to prevent crashes resulting from oncoming traffic.  Until those systems are deployed, the most used applications to alert motorists to roadside incidents, stopped police vehicles and other types of hazards is by Google, Waze, or HERE.

To help ensure the safety of service patrol staff, NJDOT has initiated a pilot study that will examine the effectiveness of using connected vehicle technology to alert the motoring public to the presence of safety service workers at an incident site. Starting in September 2018 NJDOT will pilot the use of a Beacon Hazard Lights technology to alert drivers to the presence of workers when safety service vehicles turn on their hazard lights. The piloting of the technology has received the support of the NJ State Innovation Council and a State Innovation Council Incentive Funding grant of $39,600 awarded by FHWA.  More information about the STIC Incentive Funding source can be found here.

According to Ross Scheckler, the managing partner of iCone, the product supplier for the hazard light technology to be piloted in the NJ study, the firm seeks to build technologies that will increase the availability of data about work zones to the traveling public.  Their tools alert drivers in real-time to the presence of workers, lane-closures and construction related back-ups by making them available on the cloud, where state traffic centers and navigations companies like HERE and Waze can pick them up.  A primary goal of the technology is to let drivers of vehicles know that the rescue truck or the flagger is in the road miles ahead so that the driver or the automation system can slow down and move over, or maybe choose a different route.

In the New Jersey pilot program, the iCone technology will transmit the location of worker vehicles within two minutes of the activation of a vehicle’s hazard lights. The location updates every 15 minutes and is re-transmitted if the vehicle moves more than 500 feet.

Data from 31 SSP vehicles will alert drivers via 511NJ as well as mapping & traffic apps

Thirty-one Safety Service Patrol (SSP) vehicles in Harding and Cherry Hill Yards will pilot iCone’s GPS technology to alert drivers using the 511NJ website and mapping, and traffic apps including Google Maps, Waze, and Here.  A Texas DOT study found that deploying iCone’s traffic beacons reduced crashes at a busy highway up to 45 percent (WorkZoneSafety.org). In addition, beacons deployed on roads resulted in crash cost reductions between $6,600 and $10,000 per night. Arlington is one of more than 450 partners including city, state and country government agencies, nonprofits and first responders to partner with the Waze Connected Citizen Partner program, a free data-share of publicly available traffic data, to deliver road and construction work information to cars.

Different states have used iCone’s technology in various ways, according to Mr. Sheckler. For example, Nevada has focused on relaying lane closures through iCone’s “Smart Arrow Board” modification product. Colorado on the other hand, has focused on the location of traffic cones around work zones through the ‘iPin’ product.  New Jersey’s initiative will examine the effectiveness of iCone’s technology on service patrol vehicles.

One benefit of the approach being tested is that the data appears to be comparatively low-cost and effective in reaching the traveling public through available traffic flow applications.  Mr. Scheckler, iCone’s product supplier representative, notes that most states can quickly accommodate to the data flow that the firm produces since the data feed is modeled off the Waze format.  “When states aren’t ready to integrate the data flow, the data still goes out to millions of cars through partners like Waze, HERE and Panasonic. This works so well that in states that haven’t started picking up the feed, we still have contractors using our equipment because they want their workers to show up in the car.”

In New Jersey, one of the program’s goals is to enhance awareness of the State’s Move Over Law enacted in 2009. The law requires a driver who sees an emergency safety vehicle to approach cautiously and, if possible, make a lane change into a lane not adjacent to the emergency vehicle. Emergency safety vehicles include those operated by fire or police departments, ambulance services, tow trucks and highway maintenance or emergency service vehicles, many of which display flashing yellow, amber or red lights. Drivers must create an empty lane of traffic or prepare to stop, if possible, or face fines of no less than $100 and a much as $500.

NJDOT plans to evaluate the success of the program during Year 1 and determine interest and opportunities for collaboration with transportation agencies in other states and first responder organizations. NJDOT is part of TRANSCOM (XCM), a coalition of 16 transportation and public safety agencies that improves communication and technology by the use of traffic and transportation management systems and in partnership with technology companies. XCM currently provides NJDOT incident data to Google, Waze, and Here as well as the 511NJ web and phone platform, however SSP vehicle location data is not integrated into any of these programs.

Drone Program Takes Off in Bureau of Aeronautics

Posted on

The Drone program within the Division of Multimodal’s Bureau of Aeronautics has begun to take shape as staff, funding, and a multitude of innovative ideas have come together. So what does it take to start a new and innovative NJDOT Drone program when it has never been done before? First, it starts with knowledgeable staff. A UAS (Unmanned Aerial Systems) Coordinator position was created within the Bureau of Aeronautics to lead NJDOT’s UAS initiatives. The UAS Coordinator’s role is to:

  • Provide leadership, guidance, and coordination for flight operations to Divisions
  • Ensure compliance with State and Federal Aviation Regulations
  • Ensure flight operations are based on the most current best practices
  • Coordinate FAA Airspace Waivers and ATC Authorizations
  • Develop Implementation and Staff Training Plans
  • Assist with the drafting of RFP’s for consultants
  • Keep NJDOT informed of public perception and liability

Captain Glenn Stott is the current UAS Coordinator for the NJDOT. He is a retired Canadian Air Force jet instructor, Test Pilot, and Flight Commander. Glenn is an FAA designated examiner and authorized to grant the highest level of pilot license. In addition to his aviation experience, Glenn’s understanding of emerging technologies earned him part-time positions as an Adjunct Technology Professor for both Kean and Seton Hall Universities. Glenn’s UAS background started over 20 years ago with remote control helicopters. Currently, he serves on the NASAO (National Association of State Aviation Officials) UAS Committee and is a frequent speaker regarding drone technology in the transportation industry.

Funding was the next big issue in setting up a new program of this caliber. NJDOT applied for three FHWA grants and was fortunate enough to be awarded all three. These three separate grants are: FHWA Tech Transfer Deployment Funds for a UAS Peer Exchange on Best Practices, FHWA State Transportation Innovation Council (STIC) Incentive program for equipment & training, and FHWA State Planning & Research Program for Best Practices, Policies and Procedures.

There are numerous potential areas for public use in transportation where UAS technology makes sense that many New Jerseyans may not be aware of. Some of the initiatives being explored are:

  • Traffic Incident Management
  • Structural Inspections
  • Traffic Congestion Assessment
  • Aerial 3D Corridor Mapping
  • 3D Reality Modeling from Photogrammetry
  • Emergency Response Assessment
  • Real-time Construction Project Management
  • Landfill volume calculations
  • Inspections of confined or hazardous spaces

Professional UAS operations possess many advantages over traditional methods for daily operations. Some of these advantages include a relatively low cost compared to the manpower, time and equipment traditionally used, rapid deployment, a very low carbon footprint, and the ability to operate in areas that are risky or dangerous to humans. For example, NJDOT owns and operates 250 High Mast Light Poles (HMLP) near NJ roadways. HMLPs are approximately 100-feet high, and are traditionally inspected with either binoculars or bucket trucks. While there is an inherent safety risk in performing inspections so high up near a busy roadway, UAS can alleviate this risk by providing upclose inspection of HMLPs. In addition to the safety advantage, UAS provide a higher quality inspection with closer views, higher definition photos, and with less disruption to traffic as the need for a lane closure is eliminated. To date, 241 out of 250 NJDOT HMLP inspections have been successfully completed with UAS, and photo logs have been created to identify and track problem areas. UAS structural inspection does not replace the human inspector, it is simply a tool used by the inspection team to identify potential problem areas that require closer examination.

NJDOT UAS projects are selected and pursued based on the opportunity to increase safety, increase efficiency, save money, and save time. Projects at this time range from collecting aerial photos over marshlands that cannot be traversed on foot, to aerial photos and videos of dredging projects at all stages in order to view the direction of the tide as well as the shoals and shallows. Drones are also being used to create 3D models that offer representation of a site and surface elevation. For example, a drone has been used to map a section of Route 26 to evaluate the potential of creating 3D maps for surface surveys. Areas are still being surveyed by hand in order to evaluate the accuracy of the drone survey elevations and calibrate the systems. 3D “Reality Modeling” with Photogrammetry provides real-world models for conceptual design, construction, and operational decisions, using simple photography rather than expensive LIDAR. 3D models created using drone Photogrammetry can be assessed and shared in CAD or GIS. The Association for Unmanned Vehicle Systems International (AUVSI) released their 2017 Economic Impact Report that estimates in the first 3 years of integration more than 70,000 jobs and 13.6$ billion economic growth for the United States. By 2025 they estimate 100,000 jobs created and an economic impact of $82 billion. As you can see, the possibilities for the use of UAS are numerous and innovative. The Bureau of Aeronautics looks forward to pursuing projects that enhance safety, efficiency, and cost-effectiveness for NJDOT in a variety of areas.
