Project Summary:
This research project is an extension of the intersection decision support (IDS) research initiative. Important results from IDS research include: (1) An analysis of rural expressway intersection crashes in Minnesota, including the development of a technique to identify intersections having crash rates higher than expected; (2) a statistical model that can be used to estimate or project the societal benefits of deploying a rural stop-sign assistant at rural intersections; (3) the design, development, and implementation of a comprehensive rural intersection surveillance and data acquisition system; and (4) a task analysis, design study, and simulator-based evaluation of innovative driver-infrastructure interface (DII) concepts. As a follow-on to the IDS research, this project is a five-year effort culminating in a field operational test (FOT) performed at the Minnesota test intersection in Goodhue County. This research is separated into two components: a three-year, pre-FOT effort to finalize the design of the DII, and a two-year FOT to validate the safety benefits and driver acceptance of the system. This project examined the possibility of integrating a cooperative element into the IDS system. Under the IDS program, no vehicle or driver information was delivered from the vehicle to the infrastructure. The infrastructure, however, did estimate vehicle classification using a laser-scanner-based system. This system was used to determine differences in gap acceptance as a function of vehicle length, height, and profile and to test the hypothesis that larger vehicles and older drivers require larger gaps.
