A COMPARISON OF ANALYTICAL MODEL HCM 2000 AND SIMULATION MODEL CORSIM FOR OPERATIONAL ANALYSIS OF SIGNALIZED INTERSECTIONS

Optimal design of urban intersections geometry and signal timing plans has a great impact on traffic flow quality at signalized intersections because these are locations of great congestions and interruptions on street network. The primary measure of effectiveness for defining level of service for signalized intersections is average control delay which can be measured in the field or estimated by a model. Since the HCM is the most often used traditional methodology for traffic operational analysis, HCM 2000 is briefly described and used as an analytical model example. The CORSIM model is chosen and described as an example of simulation models because it is also one of the mostly used models in the area of traffi c simulation. Delay estimates obtained by these two models are tested and compared with fi eld data samples measured at signalized intersections in Split and Mostar.
