| Summary: | 碩士 === 國立臺灣大學 === 土木工程學研究所 === 95 === Communication protocol plays an important role during the development of Intelligent Transportation Systems. NEMA puts forward NTCIP which can serve as a standard to communicate with each other and exchange information among the electronic equipment in Intelligent Transportation Systems. I believe that our country will also develop toward it.
But we have already developed the communication protocol which is used for traffic control called V3 and it also used for long years. Therefore I will evaluate their performance in the signal control by integrating three indices which are efficiency, security and air pollution. This evaluation result can provide our country the reference basis to develop NTCIP in the future. This thesis takes the delay as a efficiency index, the emissions as a air pollution index which output from Synchro and the traffic conflicts as a security index. Then I take these indices to monetize by a way of calculating social cost and establish the whole performance model to compare NTCIP and V3 in the signal operation.
This thesis takes a signal intersection as an instance to compare and analyze. The comparative result shows that the operation of Dual-Ring eight phase signal control of NTCIP displays well. It is only inferior to rotation four phases and rotation protected left turn four phases. Besides, I take NTCIP and the present PhaseOrder to compare. The result shows that although both their performance belong to the same level but NTCIP are better than the PhaseOrder which is operated by the experimental intersection in each performance index of my model. So we can know that NTCIP is relatively suitable to this intersection in operating signal control from the performance viewpoint.
