MDOT and initiative partners boast over 4,000 equipped vehicles traveling in the Southeast Michigan region:
The Michigan DOT Fleet current has 15 vehicles instrumented with the MDOT Vehicle Based Information and Data Acquisition System (VIDAS).The platform consists of a Data Acquisition System with the ability to communicate asset condition (sensor) data with high accuracy GPS via multiple communication paths (i.e., cellular, Wi-Fi, and Dedicated Short Range Communications (DSRC)).
The VIDAS platform collects the following data elements: GPS (location, speed, heading), weather sensors (air temperature, barometric pressure, pavement surface condition), Controller Area Network (CAN) Bus (vehicle diagnostic data), 3 Axis Accelerometry (X, Y, & Z deflection), and Acoustic Distance Measurement (Distance from vehicle suspension to road surface).
The purpose for gathering the data is to support current and future application development under the MDOT Data Use Analysis and Processing (DUAP) Research Project. Applications to be supported by this data collection system includes but is not limited to; Mobility, Pavement (Defect Detection, Surface Roughness) and Weather (Hazardous Condition Detection (Icey Pavement), Weather Responsive Traveler Info).
The VIDAS platform, coupled with the DUAP applications, will provide MDOT with the ability to better manage roadway assets, and improve operations and maintenance by providing more real-time data collection by utilizing a mobile collection (Connected Vehicle) platform.

The City of Ann Arbor is emerging as the international hub for connected vehicle technology research and development—a predecessor to automated vehicle deployments—and is attracting new businesses and supporting the State's largest industry - transportation. The University of Michigan Transportation Research Institute (UMTRI) has deployed over 1,500 connected vehicles in Ann Arbor. The majority of the vehicles belong to people who work and/or live in Ann Arbor. The balance of the vehicles are fleets that operate in the city such as University buses, Brewer's tow trucks, Metro Delivery courier vehicles, Golden Limo, City of Ann Arbor vehicles, and more.Safety is everyone's concern and connected vehicle technology shows the greatest promise in reducing vehicle crashes and saving lives. Through wireless technology, connected vehicles ranging from cars and trucks to buses and pedestrians could one day be able to communicate important safety and mobility information to one another and to the infrastructure that help save lives, prevent injuries, ease traffic congestion and improve the environment.
