| 摘要： | Many transportation agencies use Synchro and SimTraffic software package to optimize signal coordination. In general, this software package effectively reduces the efforts of traffic systems engineers and improves the quality of the designed coordination. Nevertheless, the initial solutions given by the software packages usually require adjustment, at both the design and implementation stages. The major objective of this research, therefore, is to reduce the time and effort needed in solution tuning and thus to improve the effectiveness and the efficiency of using Synchro/SimTraffic in arterial signal coordination design. The research outcome is expected to help traffic systems engineers reach reasonable signal settings in a shorter time. The first task of this research was to survey INDOT traffic system engineers and document INDOT's criteria for a good coordination plan. The outcome of this task served as the yardstick for other proposed design improvement procedures. The second part of the research focused on the Synchro/SimTraffic-based procedures of optimizing signal settings for urban streets and the practices and methods of using Synchro were scrutinized thoroughly. The outcome of this part of the research is a collection of supplemental guidelines for software-based selection of signal settings on urban streets. Finally, the robustness of the arterial signal coordination procedure was investigated. |
