| 摘要： | The purpose of this paper is to present the evaluation results which tested the accuracy of the data being provided by the TIC (traveler information center) known as SmarTraveler and one element of the Orion Program for deploying Intelligent Transportation Systems (ITS) technologies in the Twin Cities metropolitan area.. The hypothesis of the evaluation is that the TIC is providing reasonably accurate information, and that the quality of this information will improve over time. This hypothesis was measured by conducting travel time runs on designated routes covered by the TIC, and comparing the travel conditions observed with the conditions reported by the TIC at the beginning and the end of the travel run. The measures evaluated for accuracy were travel time, accidents, incidents (breakdowns), and construction. The travel time runs were conducted in the spring and fall of 1999. |
