| Summary: | Unsignalized intersection is implemented to regulate low volume of traffic flow. The common approach of gap-acceptance method is used to assess the performance of the intersection. However, among the drawbacks of the gap-acceptance method are the non-compliance to the right of way, design of intersections and the heterogeneous traffic condition. The method of conflict is developed to overcome these shortcomings. The occupation time of vehicle is used to calculate the capacity of vehicular movements for each conflict group. The control delay and level of service of the vehicular streams are evaluated according to the procedures in HCM 2000. Result comparison is made between different designs of intersections. The results of the conflict method are found to be comparable with the HCM 2000 using field data |
