摘要
The study reported here aimed to quantify the travel time reliability of urban midblock under heterogeneous traffic condition. Travel time index is taken into account for the measure of reliability for urban midblock. Geometric data, traffic volume count, and travel time data of seven urban midblock inKerala, India forms the database for this study. Statistical evaluation of travel time index of each midblock is calculated for reliability estimation. A model was developed and validated for travel time index with traffic flow rate to predict the travel time reliability. The exponential model gave an accurate prediction on travel time reliability with traffic flow rate. This work also concentrates on proposing level of service criteria using travel time reliability measure. Hence, these new criteria can be used for travel time reliability prediction and also act as a basis to assess the level of service criteria for urban midblock under heterogeneous traffic condition.
