Freeway Operations Study -Phase IV. Development of a Freeway Diversion Algorithm.

摘要

The study presents a detailed description of the development of a freeway diversion algorithm which will be incorporated into a freeway corridor model called CORQlC. The report begins by identifying seventeen different procedures for predicting freeway diversion,with many variations possible within each of these procedures. Five of these methods are selected for detailed consideration,and as a result of this analysis,the stepwise-linear approach to diversion is selected as being most suitable for the project needs. The incorporation of this approach into the actual algorithm and the use of a linear programming technique for assigning traffic is then described in detail. The report ends with a summary and a list of recommendations for future research.
