Abstract

Most of the travel demand in developing countries is fulfilled by private vehicles dominated by 2-wheelers due to their affordability, accessibility, and availability, which has direct effects on energy, economy, and environment. To achieve sustainable transport, policies such as electric mobility and mass transport options have been implemented which are mainly focused on technology shift based on technology cost and environmental externalities. Transport modelling in this study was carried out using an additional attribute: travel time which shows the impact of travel behaviour on the optimal modal mix and the consequent impact on energy and emissions. The scenario-based approach using the travel time budget (TTB) concept was used using a bottom-up TIMES modelling framework. The scenario analysis shows the trade-off between the speed of the vehicle, available travel time, and sustainability in transport. The result suggests that the investment in rapid transit would be the potential future mode in Kathmandu valley.

结合出行行为的客运模式组合——以尼泊尔加德满都谷地为例

发展中国家的大部分旅行需求由两轮车为主的私家车满足，因为它们的可负担性、可接近性和可用性对能源、经济和环境有直接影响。为了实现可持续交通，实施了电动交通和大众交通等政策，这些政策主要侧重于基于技术成本和环境外部性的技术转移。本研究中的交通建模使用了一个额外的属性：旅行时间，该属性显示了旅行行为对最佳模式组合的影响以及由此对能源和排放的影响。使用自下而上的TIMES建模框架使用了使用旅行时间预算（TTB）概念的基于场景的方法。场景分析显示了车辆速度、可用行驶时间和交通可持续性之间的权衡。研究结果表明，对快速交通的投资将是加德满都谷地未来的潜在模式。
