ABSTRACT

Due to the limitations of available data, the performance evaluation of national main roadways is conducted using macroscopic traffic variables (e.g., traffic volume, travel time) that consist of the cross-sectional data of network vehicle trips. To conquer this ongoing hindrance, the aim of this research is to devise a novel mobility performance evaluation index based on the concept of spatial trip coverage. Trip length distribution, a sort of derivative data extracted from big data on vehicle GPS trajectoriesy, is employed in order for the encapsulation of spatial trip coverage. To demonstrate the feasibility of the developed index, performance evaluation of national motorway sections was carried out using the index. The analysis results were similar to what transportation experts deduce. This indirectly indicates that the index, in itself, has strong explanatory and obvious discriminating power in evaluating the mobility of any road section as a member of the road network. In addition, it was demonstrated that the index could be successfully employed for the analyses of functional road classification and weekend leisure trip of motorway sections. Therefore, it is at least expected that the proposed mobility index could be efficaciously used as a policy decision-making index in the planning and operation of national highway network.
