COMPUTER SIMULATION MODEL FOR EVALUATING PRIORITY OPERATIONS ON FREEWAYS

The computerized model PRIFRE can be used to evaluate any number of different reserved-lane strategies. Although it was primarily intended to evaluate one-way normal priority-lane operations on the same side of the freeway median as the unreserved lanes, it can be used, with some manual interfacing, to evaluate wrong-way reversible lanes, separate bus roadways, and freeway design improvement strategies. Basic assumptions inherent in the model are given. Significant advantages of the PRIFRE over other models are described. The input, output, methodology for using the model, and interpretation of output are described. Traffic performance measures output to the user include single trip times, queuing times, total travel time, total travel distance, and messages. Search procedures and selection of best strategy are discussed, and areas for further research and improvement are indicated. /Author/
