Development of a Post-Processing Automation Procedure for the GPS-Based Travel Time Data Collection Technique
The travel time data collection method is used to assist the congestion management. The use of traditional sensors (e.g. inductive loops and AVI sensors) or more recent Bluetooth sensors installed on major roads for collecting data is not sufficient because of their limited coverage and expensive costs for installation and maintenance. Application of the Global Positioning System (GPS) in travel time and delay data collections is proven to be efficient in terms of accuracy and level of details for the data and required data collection of man-power.
