Traffic Simulation in Regional Modeling: Application to the Toledo Sea Port. Interim Report.

摘要

A small team of university-based transportation system experts and simulation experts has been assembled to develop, test, and apply an approach to assessing road infrastructure capacity using micro traffic simulation supported by publically available data in partnership with personnel of the Toledo Sea Port and the Toledo Metropolitan Area Council of Governments. Application activities focused on the arterial road infrastructure connecting the Toledo Sea Port to the interstate highway system via Interstate 280. Data was gathered from the Toledo Metropolitan Area Council of Governments and the Ohio Department of Transportation. A micro traffic simulation model was developed using the commercial software product AIMSUN. Multiple simulation experiments were conducted to find and propose relief for traffic bottlenecks. Simulation results showed that publicly available data was sufficient to support modeling and assessment activities. The road infrastructure was seen to have sufficient capacity to support truck movement between Interstate 280 and the seaport. The primary bottleneck was identified as the single entrance lane at the seaport security post. Adding a second lane would relieve the entrance bottleneck but cause a new bottleneck at the exit security post.
