Description

SYSTEM AND METHOD OF TRAFFIC DATA COFFECTION AND ANAEYSIS

This International Application claims priority from a complete patent application filed in India having Patent Application No. 201841047074, on December 12, 2018 and titled“SYSTEM AND METHOD OF TRAFFIC DATA COFFECTION AND ANAEYSIS”.

FIEFD OF INVENTION

Embodiments of the present disclosure relates to a survey of vehicles moving in different directions and more particularly analysing the traffic vehicles movement to create traffic data.

BACKGROUND

Effective management of existing roads can be achieved by use of new technologies. These new technologies can be used to improve the traffic capacity of the road network and provide valid data for the road construction. According to the collected data many other usages can surely come up. Vehicle counting from the video stream is one of the new technologies that help in understanding the vehicle movement on the road.

In one approach, a vehicle counting method is based on three-dimensional trajectory clustering. The calculation is based on establishing a relation between a two-dimensional image coordinate and a three-dimensional world coordinate by using a vanishing point method. Here the movement is detected by marking a particular running track cluster. The data can be more efficient if type of vehicle is also detected.

In another approach, a vehicle is counted according to the movement track. Here the vehicle is tracked from the video image extracted and processed to obtain the relative distances of the track at the same time. The calculation is done according to track distance time relationship. The mechanism does not provide details on the type of vehicles. Efficient approach would be calculating both the type of vehicle and direction of vehicle movement. Henceforth, such a type of tracking is more time consuming and are prone to errors which makes such an approach less reliable and hence less effective.

Hence, there is a need for an improved system of traffic data collection and analysis and a method to operate the same to address the aforementioned issues. BRIEF DESCRIPTION
