To deal with the imbalance between limited road space and ever-increasing traffic demand, the travel-way reorganization has been recognized as a cost-efficient way. This paper considers the evaluation of different travel lane inflow restrictions under two travel lane reallocation schemes: (i) standard travel lane width; (ii) narrow travel lane width. A computation experiment is conducted on a traffic corridor in Xi’an that carries around 6000, 8000, and 10000 person-trips per hour during off-peak, adjacent-to-peak, and AM/PM peak periods. The execution results illustrate that when the inflow restriction for private cars enter the bus-only lane varies from 0.1 to 0.8, lower total travel time of all the travelers could be achieved. As the traffic demand further increases, significant influence of lane inflow restriction on total travel time would be found. However, those differences in total travel time among various restrictions could be further reduced after adopting narrow travel-way design. Meanwhile, the efficiency of traffic system could also be enhanced for all demand levels.
