Abstract

The second-best tradable credit scheme is studied to analyse its effects on travel mobility by a bilevel programming model. The transport authority optimises the credit charging scheme to minimise the total system travel time and travellers choose paths to minimise their generalised travel costs. A genetic algorithm with some improvements on the selection operator is used to solve the proposed bilevel programming model. In numerical experiments, we discuss the implications of travellers’ path choice behaviour and traffic flow distribution under the second-best tradable credit scheme with different combinations of credit-charging links. The results show that the credit charging scheme with all links is obviously better than other schemes in the total system travel time. Besides, the credit charging scheme using congested links or duplicate links of the maximum traffic flow path as credit-charging links is effective in reducing traffic flow on congested links and mitigating the congestion of the whole transportation network.

次优信用交易方案对交通网络出行管理的影响

通过双层程序模型研究了次优可交易信贷计划，分析其对出行流动性的影响。交通管理部门通过优化信贷收费计划来最大限度地减少系统的总旅行时间，而旅行者则通过选择路径来最大限度地减少他们的一般旅行成本。我们使用对选择算子进行了一些改进的遗传算法来求解所提出的双层程序模型。在数值实验中，我们讨论了在不同信用收费环节组合的次优可交易信用方案下，旅行者的路径选择行为和交通流量分布的影响。结果表明，在系统总旅行时间方面，所有链接的信用收费方案明显优于其他方案。此外，使用拥堵路段或最大交通流量路径的重复路段作为信用收费路段的信用收费方案能有效减少拥堵路段的交通流量，缓解整个交通网络的拥堵状况。
