摘要: |
UTPS-type models were designed to adequately support planning activities typical of the 1960's and 1970's. However, these packages were not designed to model intelligent transportation systems (ITS) and support incident management planning. To overcome these limitations, improved algorithms have been proposed and tested in some markets. Unfortunately, these improvements generally have not been included in the commercially available packages and agencies continue to use UTPS-type packages. Therefore, the authors' effort is intended to supplement existing planning model capabilities by exploiting the capabilities of available micro-simulation models. Micro-simulation models can assess, for a localized area or corridor, the effect of ITS implementation and incident response. The authors introduce a modeling methodology where a sketch-level model represents the regional network and they retain a portion of the available links to develop roadway detail in the area proximate the proposed ITS technology deployment or incident. The combined system is designed to provide real-time travel information for agencies to improve traffic flow through changeable message signs or advanced traffic signals and for travelers to alter route or destination choices through pre-trip information systems such as cable television or web sites. Within this paper, a methodology is demonstrated that used a GIS interface between Tranplan and Corsim for a test case in Des Moines, Iowa, a medium sized urban area. |
