Title:

Intelligent Transportation Systems Deployment Project for the ADA County Highway District: FY99 Treasure Valley ITS

Abstract:

The Ada County Highway District, located in Boise, Idaho, was the lead agency for a FHWA-funded project to develop an Incident Management Plan for the Treasure Valley and to design/deploy ITS devices for Interstates 84 and 184. This document reports the results of the evaluation. During the evaluation, changes in the average speed under different weather conditions were documented. (The average speed in clear, dry conditions was 62.3 mph.) The average reduction in freeway speeds for all project locations during snowy weather conditions was 17.3 mph. During rainy weather conditions, however, the reduction in the freeway operational speed was less drastic and averaged 1.8 mph.
