| Summary: | Abstract The customized bus (CB) service of large transport terminals can provide passengers with convenient transfers and door‐to‐door services, which has the potential to help ease the pressure of arriving passenger flow in large transport terminals. Considering the costs of operators and passengers, this paper establishes a multi‐commodity network flow optimization model to simultaneously obtain departure schedule, passenger‐to‐vehicle assignment and routing under the condition of multiple vehicle types. It provides more passengers with high‐quality CB service and obtains higher vehicle capacity utilization. Accordingly, the solution is proposed that combines a branch‐and‐cut algorithm with grid‐density‐based clustering. An illustrative example verifies the effectiveness and tests the impact of the departure time‐window. The case study of Chengdu city compares the results under different types of vehicle schemes and conducts the sensitivity analysis of penalty and minimum load ratio. The experiments conclude: (i) The proposed algorithm stably improves computation speed (76.38%) without affecting the optimal results; (ii) a loose time‐window can serve more people, but the excessively loose one no longer has impacts on the results. (iii) The multi‐type of vehicle scheme performs best compared to the single type of vehicle schemes. |
