Alaska Department of Transportation & Public Facilities Intelligent Specialty Vehicle System Pilot Program Report

The Intelligent Specialty Vehicle System (ISVS) is equipped with Precision Global Positioning System (PGPS) technology which is delivered in the form of Real Time Kinematics (RTK) to the vehicle from a single dedicated GPS base station. The vehicle mounted system has integrated collision avoidance radar technology designed to provide the driver a means to maintain desired lane position and avoid collisions with obstacles during periods of low visibility. The PGPS provides position information to the vehicle which can be as accurate as 3 cm. Distance from the PGPS determines the final accuracy, the further the ISVS is from the PGPS, the lower the accuracy. This project is motivated by the fact that specialty vehicles often must operate under inclement weather conditions. The driver assistive system improves safety for the specialty vehicle operator by providing the necessary cues for lane keeping and collision avoidance normally unavailable during poor visibility conditions. The driver assistive system, when placed in snow and ice control vehicles, improves safety by facilitating all-weather road services which keep roads open and passable for other emergency vehicles and the general motoring public. A snow blower and snowplow are the primary vehicles of the ISVS project for the Alaska Department of Transportation and Public Facilities (ADOT&PF). The project implemented, operated and evaluated all necessary infrastructure components, in-vehicle sensing technology, in-vehicle processing including algorithms, and driver-vehicle interfaces. Testing of these systems took place on state highways using state vehicles under all conditions including low-visibility conditions such as snow, blowing snow, ice fog, and night.
