A method for evaluating the effectiveness of improving public transport services, parking fee policies, and park-and-ride facilities in order to encourage the use of public transport

Enhancing the quality of public transport services, implementing effective parking fee policies, and developing park-and-ride facilities are common solutions that urban planners and city governments apply to encourage public transport use. However, estimating the impact of these measures on increasing public transport usage during the solution design process is challenging. This article proposes an approach to assess the effects of these measures in the solution design process, which policymakers or city governments can apply to formulate suitable policies and feasible measures aligned with the local context. The approach begins with a survey on travel behaviour, followed by formulating a mode choice model to assess the sensitivity of the mode share to factors affecting mode choice. This approach is applied to Da Lat city, and the research results indicate how to enhance public transport services, determine appropriate parking fee levels, and establish park-and-ride facilities to achieve a public transport share of 5%, 10%, 15%, or higher. One of the main research results shows that the Park and Ride solution is feasible. Additionally, to achieve a growth rate of public transport volume up to 10%, it is necessary to improve public transport quality services combined with an increase in car parking fees in the downtown area
