1. A computer-implemented method for identifying parking areas comprising:
- providing vehicle trajectory data of vehicles collected from a sensor network having a plurality of sensor stations for detecting vehicles, the sensor stations of the sensor network are distributed in a geographical area of interest, the vehicle trajectory data is stored as vehicle trajectory data records in a vehicle trajectory table, wherein a vehicle trajectory data record of the vehicle trajectory data comprises,a vehicle id identifying the vehicle detected,a sensor station id identifying the sensor station detecting the vehicle, anda captured time which is the time that the sensor station detected the vehicle;
pre-processing the vehicle trajectory data records by an analysis system to generate a tracking table of vehicles;
storing the tracking table in a data model of an analyzer of the analysis system; and
analyzing the data model to determine an interstation parking area between first and second sensor stations of interest based on input parameters from a user.

Abstract
A framework for identifying parking areas from vehicle trajectory data is described herein. Vehicle trajectory data collected from a sensor network having a plurality of sensor stations for detecting vehicles is provided. The vehicle trajectory data is pre-processed to generate a tracking table of vehicles and analysed to determine an interstation parking area between first and second sensor stations of interest based on input parameters from a user.
