Cooperative Vehicle-Highway Systems and       Dynamic Vehicle Probe Data Integration into an Advanced Traffic Management System

Every modern vehicle on the road today generates a standardized set of vehicle-specific data not currently available from traditional Intelligent Transportation Systems (ITS). These data sets, if harnessed, can provide a vast amount of useful information to public and private agencies responsible for transportation management, incident management, transportation modeling, freight management and tracking, and emergency management.

Cooperative Vehicle Highway Systems link the vehicle with the roadside and close the loop between the intelligent vehicle and the intelligent highway. Many different communications mediums can be used to connect the vehicle to the roadside, including:

• Cellular
• WiFi
• WiMAX
• DSRC
• Millimeter WAVE

A single-board computer with peripheral hardware collects data from the vehicle CANbus and transmits over a wireless infrastructure.

Experience and Capabilities

Southwest Research Institute® (SwRI®) engineers have experience working with many different forms of wireless communications and have developed algorithms capable of utilizing the vehicle-to- infrastructure communication channel.

SwRI engineers research, design, integrate, and test vehicle network systems for commercial, DOT, and military applications, including:

• Integration of dynamic vehicle probe data into Advanced Traffic Management Systems
• Maintaining device anonymity while disseminating information in a 3-dimensional plane
• Heavy-duty vehicle-based probe system
• National and international standards-based development

 SwRI engineers develop systems in various mobile computing environments, including:

• Small device development (Windows CE, Windows Mobile)
• Alternative platforms (single-board computer, PC104, PDA, smart phone)

Cooperative Vehicle Highway Systems projects include field testing on a 1.16-mile test track located on the Institute grounds.

Dynamic probe data systems provide traffic management operations with extended data sets not available from traditional Intelligent Transportation Systems. The Map Interface application displayed was utilized at the permission of the Texas Department of Transportation.
