Method for generating traffic data using electronic maps
A recently granted patent (Publication Number: US11922802B2) outlines a method for generating traffic data within a navigable network covered by an electronic map. The method involves obtaining positional data from devices moving along segments of the electronic map, estimating average penetration rates for congested and non-congested segments, and using this data to determine traffic volume and density. The system described in the patent includes processors and memory to carry out these calculations, allowing for the estimation of traffic conditions based on device movement data.
Furthermore, the patent details the use of direct measurements of traffic volume and density, determining average penetration rates for different segments or regions, and calculating relative errors for the estimated traffic data. The system can store and display the estimated traffic volume and density for user access. The method described in the patent aims to provide accurate and real-time traffic information by analyzing device movement data within a navigable network, offering insights into traffic volume and density for improved navigation and planning.
