The overall goal of this project was to assist MDOT in developing a long-term expansion and enhancement plan for the Michigan Connected Vehicle deployments. These expansions and enhancements will further define and support the technology and developments in the connected vehicle community. The Connected Vehicle program and continued device deployment are aimed at broadening the effectiveness, number of locations/coverage area, and dramatically improving the quality/ responsiveness of data received from and through the Roadside Units (RSUs).

Connected Vehicle Infrastructure Design

LocationMichigan (Statewide)
CategoryMobile LiDAR / GIS

Since the Broadcast message being transmitted to the RSUs is only as valuable and accurate as the data collected, the use of accurate Mobile LiDAR was essential in the collection of required geometric features. The following geometric features were collected and extracted for each location: lane lines, edges of pavement, cross walks, stop bars, center of lanes, a geographical center of intersection for each as needed location. Since 2017, SSI has successfully collected thousands of lane miles of connected vehicle infrastructure throughout Michigan.

Mobile LIDAR data was also collected in a manner that achieved a high accuracy in order for the datasets to be utilized and recycled downstream for other purposes.

The SSI Solution

SSI was selected to provide Mobile LiDAR services on an as-needed basis for MDOT Connected Vehicle projects. Tasks for this project consisted of LiDAR data acquisition, extraction of features, and the development of Connected Vehicle deliverables in a GIS format.
