Project Description
2017 ITS Architecture Update

The goal of this project is to provide maintenance support to the Minnesota Statewide Regional ITS Architecture by updating the current architecture in conformance with the latest version of the National ITS Architecture.

Connected Corridors

The Connected Corridor is a vision for a key regional arterial to be outfitted with Connected Vehicle (CV) communications infrastructure enabling exchange of information with nearby vehicles. This Vehicle-to-Infrastructure (V2I) technology, deployed at traffic signals, will allow for deployment of a number of applications to improve safety and efficiency of roadway users.

Minnesota Autonomous Bus Pilot

Autonomous Vehicle technology is rapidly developing around the world. Minnesota offers unique climate challenges that are much different from others currently testing these technologies. Deploying an AV pilot project in Minnesota will better position the State to influence national policy and prepare Minnesota transportation owners and stakeholders for the future.

MnPASS Enforcement Assistance System (EASy) The MnPASS Enforcement Assistance System (EASy) is a project focused on providing a tool to improve the safety and efficiency of State Patrol Officers who monitor and enforce the MnPASS Express Lanes. EASy mimics the operation of a two-trooper team, where one officer observes vehicles at a MnPASS tag reader site and another is positioned in a patrol car downstream to pull over suspected violators. Vehicles that do not have a successful transponder read are imaged by a camera. That image is then sent to the trooper vehicle where it is assessed to determine if a violation is taking place.
Next Steps for Work Zone Challenges To utilize low cost, high benefit technology solutions, it is important to link the appropriate technology with a project, secure funding early in project scoping, and acquire full support by the Project Stakeholders for ITS or Intelligent  Work Zone (IWZ) implementation.  This project will identify key projects to demonstrate ITS/IWZ technology deployments in order to establish a sustainable approach to address the top work zone challenges.
Real-Time Integration of Arrow Board Messages into Traveler Information Systems This project will equip arrow boards used by Twin Cities metro area maintenance shops with the functionality to export status and location for stationary and mobile/rolling closures. The project will then integrate the reported arrow board status information with the MnDOT Intelligent Roadway Information System (IRIS) and the MnDOT Condition Acquisition and Reporting System (CARS).
Rural Intersection Conflict Warning System (RICWS) Evaluation & Design Investigation The Rural Intersection Conflict Warning System (RICWS) has been deployed across the state to aid motorists to safely cross thru-STOP intersections.
The objectives of this project are: (1) to conduct a human factors analysis of the current RICWS sign and identify what features or layouts may be problematic for proper and easy interpretation of its message; (2) examine multiple alternative designs through iterative usability studies to identify candidate sign options; (3) and test candidate sign options in the driving simulator to ensure proper interpretation of the sign message and safe gap acceptance for passing through the intersection.

Truck Parking and Management System (TPIMS)

This is a TIGER Grant, multi-state Truck Parking Information and Management System (TPIMS) project that is being led by the Mid America Association of State Transportation Officials (MAASTO) to address truck parking safety and efficiency needs.  The Minnesota sites are located at rest areas leading into the Metro area along I-94 and I-35.

Variable Pedestrian Clearance Interval The Variable Pedestrian Clearance Interval (VPCI) project utilizes automated pedestrian detection via video-based pedestrian detection sensors in order to improve safety and efficiency. The video camera sensors are installed at the signal pole at each end of the crosswalk. The system is programmed for a minimum pedestrian countdown time. However, when a pedestrian is detected within the crosswalk by the cameras the "Flashing Don't Walk" time will be extended to accommodate these pedestrians. If the minimum countdown is reached, and no pedestrians are detected within the crosswalk, the "Flashing Don't Walk" time can be skipped altogether.
Wavetronix Vehicle Detection and Implementation The Wavetronix Vehicle Detection and Implementation project involves installation of Wavetronix sensors at two test intersections. Wavetronix utilizes non-intrusive radar detection to act in place of traditional loop detection. The radar detection system is able to collect performance measurement data and enhance safety at traffic signals by minimizing the number of vehicles the traffic signal system exposes to an intersection-approach dilemma zone. The detection system tracks the speed, range and estimated time of arrival at the stop bar of each vehicle it detects.
Work Zone Accident Reduction Deployment Evaluation (WZARDE) This WZARDE project is an evaluation of the original 2012 SCorE-WZARD project.
