Arterial Management Center Staff Augmentation
New Jersey Department of Transportation
Traffic Engineering & Intelligent Transportation Systems
The NJDOT Arterial Management Center (AMC) is a centralized location which NJDOT and consultant staff manage mobility and safety for NJDOT arterial roadways. The NJDOT AMC modernizes traffic operations through AI-powered adaptive signal control, real-time data analysis, and predictive analytics. This proactive system reduces congestion-related crashes, provides travel delay reductions, and minimizes maintenance through early identification of system errors. TechniQuest Corporation (TQC) supports the Atkins Realis Team and the NJDOT AMC with four (4) full-time staff reporting on-site to monitor and analyze real-time traffic conditions.
TQC’s role at the AMC includes monitoring real-time traffic conditions and the SCATS transportation interface system along specific New Jersey corridors. TQCs AMC Staff is responsible for monitoring the various adaptive traffic signal systems, detection systems, vehicle probe data, and other systems/platforms related to traffic signal performance. The TQC operations team focuses on the monitoring of traffic flow, signal performance, and reports on all incidents pertaining to the exact corridors. These operators also leverage the ATSPM platform to generate key performance metrics and conduct system analysis for NJDOT’s Adaptive Signal Control Technology (ASCT) corridors. TQCs on-site analysts recommend and implement signal timing adjustments when incidents occur and are affecting signal performance. The overall goal of these metrics and adjustments is gaining efficiency, reducing vehicle delays, balancing major/minor flows, managing queues, and improving overall throughput.
One common method implemented by TQC operations staff for reviewing signal performance in real-time is monitoring maximum and residual queue lengths. Increases in queue can occur from general variations in traffic flow, such as peak hour operations, or from reported incidents on the roadway, such as a crash or disabled vehicle. The operators monitoring traffic report these incidents. The TQC team works collaboratively with NJDOT and Atkins to recommend and implement signal timing revisions, such as increasing cycle length and/or green time at SCATS-assisted intersections when queues are formed to help reduce delay or adding “time-gain” to certain intersections so all phases can be served depending on the time of day.
Other metrics for assessing performance may include assessing detection recalls on minor roadways and the minimum/maximum green-time assignments. Incidents on major corridors may have more impact on cross-streets, and adjusting signal recalls to allocate the necessary green-time to minor streets is another mitigation option. TQCs team also analyze and process traffic data to identify trends, areas of congestion (reduced speed), and recommend actions for improvements.
TQCs operators also help monitor the health of the intersections by reporting system errors that can occur either with the detectors or other signal components. TQC AMC Operators are responsible for reporting the health status of traffic signal subsystems (hardware and software) on adaptive traffic signal system corridors to NJDOT Mobility Engineering and the AMC Managers regarding several items, including Vehicle Detection, Traffic Signal Communication, Traffic Signal Software Applications, and Intelligent Transportation Systems (ITS). TQCs operators are responsible for reporting and identifying when an intersection system goes offline. Reporting these occurrences quickly and accurately allows the NJDOT to configure/troubleshoot the equipment proactively.
Staff Augmentation services for the NJDOT Arterial Management Center (AMC) occur at the Trenton HQ of NJDOT.

Grand Central Terminal Train Shed Rehabilitation
NYCDOT / MTA
Traffic Data Collection
Project Goal: TQC supported Dewberry Engineers in the completion of traffic data collection and traffic engineering analysis within the Grand Central Terminal. The goal of TQCs efforts is providing traffic data to support the preparation of an Environmental Impact Assessment and Technical Memorandum describing the screening process for the review and approval of NYCDOT. All traffic data collection was required to be completed per the requirements of the NYCDOT CEQR Manual.
Scope of Work: TQC scope includes collecting data at 30 signalized intersections within Manhattan Borough between 45th Street and 58th Street along Lexington Avenue, Park Avenue and Madison Avenue. The efforts also included installing ATRs at 8 locations and performing pedestrian traffic studies at 10 locations. TQC staff also completed field inventory of all intersections, reviewed parking demand and capacity at 78 parking garages and completed
The completion of the data collection effort required coordination with NYCDOT, including the completion of a NYCDOT Camera Deployment Request. This request outlined all scheduled data collection locations and equipment and was also submitted for review and approval by the Grand Central Partnership.
TQC completed traffic data collection over a 10-day time period in December of 2023, and then repeated the same effort in June of 2024. The goal of this effort was to establish a comparative analysis of traffic data, as well as establish sufficient dates/times to satisfy NYCDOT CEQR requirements.
TQC staff also performed travel time and delay studies along Madison Avenue, Park Avenue and Lexington Avenue. Travel time and delay runs will also be collected using the “floating car technique” in which the survey car travels at the prevailing speed of the traffic stream. This method requires a driver and data recorder in each car to record the travel data through each of the air quality analysis sites during the same time as the traffic counts are collected. A total of two vehicles would be used to collect the required six to nine runs per link for each analysis hour.
Passaic County Regional Traffic Signal Optimization
Passiac County
Traffic Data Collection
The Passaic County Regional Traffic Signal Optimization project was a federally funded CMAQ program aimed to reduce congestion, vehicle emissions and increase safety. The project encompasses a 15-mile corridor with over sixty traffic signals. TQC teamed with Colliers Engineering and Design to collect traffic data, develop improved timing schemes, and propose recommendations for signal upgrades and improved safety.
Project Goals: The goal of the project was to optimize traffic signal operation throughout the entire corridor or within clusters of the corridor. TQC objective within this goal was to develop a program to collect traffic data at all signalized intersections along the corridor (as well as key adjacent intersections) and establish baseline conditions for signal optimization.
Scope of Work: TQC developed an approach to collect TMC data in clusters over a one-month period. This method was necessary as the overall scope includes eighty-one total intersections, sixty-six along the primary corridor. The schedule developed enabled the teams to collect data in four clusters based on existing and anticipated signal coordination and is included below as a reference.
TQC staff also performed baseline travel time studies for three weekdays and one weekend for the corridor which were utilized to assess corridor synchronization. The travel time studies completed will also serve as the before condition of the “Before and After Study.” TQC will complete the “After” travel time runs following the implementation of updated signal timings by Passaic County.
The scope of work included field inventory, traffic data collection, travel time analysis and crash data analysis. TQC staff supported the project by completing the following tasks:
-
Deployment, Monitoring and Processing of 81 Turning Movement Counts using MioVision Scout Video Detection Equipment.
-
Bidirectional, 24-hour ATR counts for a 10-day period to record volume and classification data at 11 sites (22 total ATRs).
-
