Using GPS Trajectories to Adaptively Plan Bus Lanes

Abstract

Since bus prioritization policies can help mitigate urban traffic jams, the planning of bus lanes has drawn considerable attention. Existing methods suffer from a common limitation, which is that the limited spatial adaptability resulting from certain road condition information cannot be directly specified. Many bus GPS trajectories have been accumulated and can be contiguously gathered if needed. This paper proposes a trajectory-based bus lane planning method. First, we formulize the bus lane planning problem as a multiobjective optimization problem in which the road conditions, traffic flow, connectivity of bus lanes, and construction cost are organized as four constraints, and road utilization and bus punctuality are modeled as two objectives. Then, an evolutionary algorithm-based method is presented to solve the problem. We tested the model in the Nanshan District, Shenzhen City, China. Through a comparison with existing survey-based methods, the parameters associated with road conditions in this method are directly extracted from GPS trajectories, and this method is more effectively deployed than other methods. Since GPS trajectories can cover a wide area if needed, and because the proposed method can be effectively executed, this method can be adapted to large urban scales.

Assessment of Accessibility of Public Transport by Using Temporal and Spatial Analysis

“…Temporal accessibility can refer to both the time required to reach a bus stop from the starting point and the time required to travel between two bus stops using public transport [49].…”

A Method for the Identification of Critical Interstop Sections in Terms of Introducing Electric Buses in Public Transport

“…Spatial mapping of bus routes in a city is possible using a Geographic Information System (GIS) [19,20]. Data on the road and street network layout are available, for example, from OpenStreetMap [21]. Many bus operators provide standard data on the General Transit Feed Specification (GTFS), which contains specific information on bus routes, for example, distances and bus stop sequences [22].…”
