Abstract :
This study investigated the feasibility of utilizing the ITS deployment analysis system (IDAS) program version 2.2 as a tool for evaluating intelligent transport systems (ITS) deployment plans. First, an online survey was conducted among MPO staffs in the US to understand the usage and the issues of the IDAS program for the ITS deployment plan evaluation. Second, case studies were carried out to examine the benefits of deploying several popular ITS options. The case studies of Hampton Roads area and a simple network with six selected ITS options identified three issues: (i) overestimation of ITS option benefits when the benefits are estimated from travel time savings, (ii) incorrect interpolation on travel time reliability rates for non-integer V/C ratios, and (iii) insensitive cost savings for combined ITS options.
