A framework for the systematic study of vehicular mobility and the analysis of city dynamics using public web cameras

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention provides a comprehensive framework for large-scale monitoring, collection, analysis, modeling, and visualization of vehicular mobility data using public web cameras. The system automatically gathers traffic snapshots from many cameras, cleans and processes the data using machine learning, extracts spatio-temporal traffic patterns, and enables visualization and predictive analysis of traffic flows for cities. The extracted data supports city profiling, traffic prediction, scenario generation, and comparative analysis among different cities.

Patent Abstract

A method of providing a framework for a large scale monitoring, collecting, analysis, modelling and visualization of vehicular mobility over a communication network, wherein the method comprises the steps of: a) monitoring, collecting and storing a plurality of traffic snapshots from a traffic server on a regular basis using a network communication protocol; b) within an automated and self-learning process, detecting at least one snapshots deemed with error and/or useless traffic information and removing the detected at least one snapshot from the plurality of snapshots; c) within a systematic process, extracting and storing large-scale traffic information from the traffic snapshot images; and d) using the extracted traffic information for the purpose of modelling and analysing vehicular traffic; and/or e) using the extracted traffic information for the purpose of knowledge discovery of vehicular traffic; and/or f) using the extracted traffic information for the purpose of realistic vehicular modelling, scenario generator and the analysis of network routing protocols in case of moving vehicles; and/or g) using the extracted traffic information for the purpose of traffic visualization and knowledge of vehicular traffic levels at different instances of time and spaceand / or h) using the extracted traffic information for the purpose of traffic visualization and knowledge of vehicular traffic levels at different instances of time and space; and/or i) using the extracted traffic information from traffic images, collection of driving distance and driving time between the camera locations and places of attraction, number of lanes, width of roads for city profiling and using any of all of these information for the design and analysis of new metric to capture spatial, temporal and spatio-temporal features that will qualitatively and quantitatively model and profile cities and help to compare them with each other.
