Research/Project Description

Simulation Study of a Bus Signal Priority Strategy Based on GPS/AVL and Wireless Communications:
The vision of the VII (Vehicle Infrastructure Integration), is to deploy a nationwide network that enables communications between vehicles and roadside infrastructure for various transportation operations and applications.

Signal priority requests for transit or emergency vehicles can potentially be sent to the signal controller through the vehicle-to-infrastructure communication architecture described in VII. Communication with the roadside unit (e.g., traffic controller) for signal priority may be established using the existing 802.11x WLAN on the bus or the DSRC (Dedicated Short Range Communication) 802.11p protocol currently under development for wireless access to and from the vehicular environment.

Work in next phase will oncentrate first on the more readily available protocols. However the system will be designed so that it can be ported to the new 802.11p protocol when it becomes more readily available.

Research/Project Description

Minnesota in-Vehicle Signing Project: Minnesota is planning a test of an interim in-vehicle signing application that will use OBE and RSE only. The test will determine if real-time safety information can be transmitted from a stand-alone roadside device to a driver via an after market product within vehicle. The test will also evaluate the effectiveness of in-vehicle signing for work, school and speed zones, in addition to curve and intersection collision warnings.

Research/Project Description

We have an in-progress contract with Ford for a "Vehicles as Sensors" project. It is retrieving data from some fleet vehicles using cellular communications and integrating the resulting data into the CARS database which feeds Minnesota's 511 system. Future work may include adding additional communication approaches and providing a means to provide the traveler information back into the vehicles.
