The strategies on the design and operations of bus lane during peak hours are examined. The operations of bus in different settings of lane management and bus stops distance are investigated in order to improve bus travel speed. A simulation model is developed to represent the heterogeneous traffic flow on a corridor in Phnom Penh, Cambodia. VISSIM simulator is used, and the parameters are calibrated for validating travel times of multiple vehicle types by structural equation modeling. The results suggest that bus lane exclusively used by bus and motorbike improves travel time of bus, car and motorbike by 33%, 8% and 6% respectively.
