360 Degree Radar

 

 

The goal of this project is to perform traffic data collection activities using a 360 Degree Radar Information System, test the accuracy of the system, and provide a detailed summary of traffic data and driver behavior at the selected field site located on I-94 east of the Lowry Hill Tunnel near the I-35W overpass.  The system will utilize a 360 degree radar unit provided by Navtech Radar (circled in picture below) to gather real-time traffic data from the freeway site and software installed at the MnDOT RTMC (also pictured below) will detect traffic incidents based on analysis of the traffic data collected.  The AECOM Team is responsible for deployment of the system, data collection, monitoring and reporting.
   

511 Traveler Information System Enhancements

 

This project included four separate but inter-related tasks that MnDOT elected to pursue under the 2014 Innovative Ideas ITS Program, all of which enhance its existing 511 traveler information service: 1) Integrating Public Input in 511; 2) Third-Gen Segment: Winter Driving Condition Reports; 3) Automated, Statewide Travel Times and Delays for 511; and 4) National Weather Service Integration for 511.

   
Arterial Real-Time Traveler Information Commercial Probe Data Project
The Arterial Real-Time Traveler Information Commercial Probe Data project is intended to demonstrate an innovative, non-infrastructure based relatively low-cost approach to collect real time traffic data on metro area arterials and a rural interstate construction work zone, to provide real time traffic information to motorists. Data provided will augment traffic data currently being collected by MnDOT to provide a broader picture of traffic conditions in the metro area and a rural freeway. Also, this project plans to validate the accuracy and reliability of traffic non-infrastructure based data collection on a major state arterial and rural interstate construction work zone.

 

 
Arterial Travel Time Using Bluetooth

 

The Arterial Travel Time project is focused on demonstrating how the use of Bluetooth technology can be a cost-effective real time and accurate travel time information along Minnesota's arterials and will also demonstrate how travel time information might be used to measure performance of arterial traffic management and operations.
   
Blow Ice Signalized Warning System Design

Certain open field areas have a history of snow and sleet blowing across the road and creating slippery conditions in a relatively short section when the rest of the highway is clear and dry.  Not only does this condition violate driver’s expectations increasing risks of crashes and injuries, it also prevents MnDOT from obtaining their goal of clear roadways during the winter months.

This project will provide a design for a dynamic warning to drivers when the pavement becomes icy. Maintenance will also be informed when these conditions exist so that they may respond to the condition.

 

 
CICAS Cooperative Intersection Collision Avoidance Systems The CICAS initiative focuses on defining the optimal combination of infrastructure and in-vehicle systems needed to address a full range of intersection crash problems.

   
Enhanced Speed Compliance for Work Zones The goal of this project is to deploy and evaluate a mobile system that can be used by state patrol officers to safely conduct manual on-site speed enforcement in work zones.  The system takes advantage of a detection and monitoring system already developed for MnDOT and the State Patrol as part of the Enhanced Red Light Enforcement (ERLE) system in St. Cloud, MN.  The proposed work zone site or sites will be jointly selected by MnDOT and the State Patrol.  The AECOM Team will be responsible for the design, development and deployment of the system, as well as data collection, monitoring and reporting.
   
Estimating Work Zone Performance Measures on Signalized Arterials The Project will utilize SMART-Signal, a technology that gathers traffic signal data in real-time, to monitor work zone operations on a signalized arterial, document performance measures, and adjust signal timing parameters when necessary. This project will develop a method for measuring work zone performance using real-time data. A toolbox will also be developed to mitigate congestion levels that exceed acceptable thresholds, such as adjusting signal timing or making changes in traffic control.
   
Evaluation of Arterial Real-Time Traveler Information Commercial Probe Data The Evaluation of Arterial Real-Time Traveler Information Commercial Probe Data project goal is to help MnDOT assess the accuracy and quality of the speed and travel time data delivered within the project.  Also, the evaluation will assess the usability, usefulness and costs of the commercial probe data.  The results of the evaluation will provide MnDOT information for making future business decisions.
   
Evaluation of MnDOT Rural Travel Times During Construction This report summarizes an independent evaluation of the MnDOT Rural Travel Times During Construction Project.

Strategic ITS Research and Development Plan

The ITS Development Unit in MnDOT’s Office of Traffic, Safety & Technology is responsible for researching, developing, field testing and providing technical support for new ITS products, methods and systems. Once these products, methods and systems are developed to the point of being effective and reliable, other functional areas of MnDOT, such as MnDOT district offices, are then responsible for any routine deployment and operation of the developed systems. To focus on ITS development opportunities that will provide the best benefit, the ITS Development Unit undertook this project to analyze ITS development needs and objectives to identify emphasis areas, strategies to address those areas, and development needs to implement those strategies.

   
Systems Engineering for Centralized Traffic Signal Control Software (CTSCS)

This project used the systems engineering process to develop specifications for a new Centralized Traffic Signal Control Software (CTSCS). Centralized traffic signal control allows the operator to manage operations remotely via higher speed, constant communications with the field. This type of control is used on approximately one-third of MnDOT’s Metro District signal system, particularly those intersections on critical, high-volume routes. MnDOT’s current central control system is no longer supported by the vendor. This is the primary driver behind MnDOT’s procurement of a new CTSCS.
