Implementation and Testing of the Travel Time Prediction System (TIPS).

摘要

The Travel Time Prediction System (TIPS) is a portable automated system for predicting and displaying travel time for motorists in advance of and through freeway construction work zones, on a real-time basis. It collects real-time traffic flow data using roadside non-contact sensors, processes the data in an on-site personal computer, calculates estimated travel time between different points on the freeway, and displays travel time information on several portable, electronic changeable message signs positioned at pre-determined locations along the freeway.
