MnDOT to pilot radar system for traffic monitoring

The US’s Federal Communications Commission (FCC) has given approval to the Minnesota Department of Transportation (MnDOT) to trial the use of a radar system to monitor and study traffic flow on Interstate 94. The idea to use radar for traffic monitoring was originally submitted to the agency under its Innovative Idea Program last June. Currently, the proposal is to deploy a traffic detection system that can monitor six lanes of traffic and two overhead bridges from one location. The objective is to

The US’s 2115 Federal Communications Commission (FCC) has given approval to the 2103 Minnesota Department of Transportation (MnDOT) to trial the use of a radar system to monitor and study traffic flow on Interstate 94.

The idea to use radar for traffic monitoring was originally submitted to the agency under its Innovative Idea Program last June. Currently, the proposal is to deploy a traffic detection system that can monitor six lanes of traffic and two overhead bridges from one location.

The objective is to gather accurate traffic and congestion information from the trial, with the collected information to be provided to necessary staff for emergency situations. The information is also to be stored to provide congestion and incident metrics. As a side benefit, the proposed system can also detect lane changes and manoeuvres, helping identify driver behaviour.

The proposal has been accepted by MnDOT in conjunction with its partner 3525 AECOM, a consultant and technical services partner on the project, and RhiZone, a local innovation partner.

The ultimate goal is to perform traffic data collection activities using the 360 degree radar, test the accuracy of the devices, and provide a detailed summary of traffic data and driver behaviour at the selected field site, which is located on I-94, just east of the Lowry Hill Tunnel near the I-35W overpass.

The system will use a radar unit provided by 819 Navtech Radar to gather real-time traffic data from the site, and software installed at the MnDOT Regional Traffic Monitoring Center (RTMC) will detect traffic incidents based on analysis of the traffic data collected.

The AECOM Team will be responsible for deployment of the system, data collection, monitoring and reporting. The next steps in the pilot project include producing the Systems Engineering documentation to guide design and deployment activities, and to deploy the radar system for six months of operation, beginning in spring 2015.

    Active traffic management - challenges and benefits
    Minnesota DoT has built one of the most intensive Active Traffic Management (ATM) systems on the road today. Like many ITS deployments, the state has gained benefits but also faces many challenges, as Pete Goldin reports. Smart Lanes is the brand name of Minnesota Department of Transportation’s (MnDoT) ATM system on I-35W in the Twin Cities Metro Area. The original system covered 16 miles of I-35W south of Minneapolis starting in 2009, and was extended by two miles in 2011. Additional ATM equipment was inst

    Radar reinforces detection efficiency
    Radar can have distinct advantages in some transport-related situations as Colin Sowman found out during a visit to Navtech Radar. Despite tremendous advances in machine vision techniques, the accuracy and reliability of camera-based detection systems suffer during periods of poor visibility where other technologies may offer an alternative. Radar is one such technology. It too has seen significant development in recent years and according to Navtech Radar, the technology can often fulfil detection and moni

    Radar effective as detection tool for hard shoulder running
    Navtech Radar's millimetric-wave systems are being researched on the M42 in England to look into how this type of detector can assist in the opening of the hard shoulder as an additional running lane. Here, the company's Stephen Clark talks about the technology being used. In England, the Highways Agency's (the HA, an executive agency of the Department for Transport) Managed Motorways system - formerly called Active Traffic Management - uses electronic signs and signals mounted on gantries to direct drivers

    Long range radar aids wide area traffic monitoring
    Applications of long range radar technology are demonstrating its effectiveness as a first line of defence for highway managers – adding greater resilience and capability to existing systems. Development efforts are bringing long range millimetric wave radar to the fore as a very useful tool for managers of highway networks. Application of radar for wide area monitoring in traffic management remains in its infancy. But recent projects are demonstrating how it can now serve to enhance detection of incidents
