This research aimed at the study of morning peak's vehicle occupancy rate of passenger cars entering into Bangkok's city centre through the city's at-grade road network. Occupancy rate of pick-up vehicle was included into its investigation due to its popularity for passenger usage especially during the peak hours period. Analysis data was collected on 24 entrances into the city centre along Ratchadapisek ring road which was used as Cordon line surround the city centre. Vehicle occupancy rates were analysed for different types of these passenger vehicles, which were classified into private passenger car, private pick-up, and public taxi. The difference between occupancy rate of private and public passenger vehicles were analysed together with the overall vehicle occupancy rate for all of the vehicle types. Time series analysis of occupancy rate of each type of vehicle was also presented in this paper.
