Intersection Movements Delay Modelling Based on Crowd-sensed Global Positioning System Trajectory Data
Developing accurate large scale transportation models, used to guide policy adoption and evaluate infrastructure alternatives or changes in sociodemographic conditions, is data and resource intensive. This research proposes a new method to model intersection movement delay using crowd sensed Global Positioning System (GPS) data. This is done by providing a general definition of turning movements and extracting travel times from GPS trajectory data analysis. A simple method is also proposed to integrate the observed delays per movement type into volume-delay functions. The spatial definition provided for turning movements captured the different speed profiles per turn type. The significant difference in mean speeds for different turn types demonstrated the importance to integrate turn penalty functions based on real observations and the importance of crowd-sensed GPS data. A simple technique is also proposed to integrate the proposed method into the volume-delay functions used in large scale transport models.
