Abstract:
1. A method comprising: defining at least one traffic network, each traffic network comprising a plurality of road segments; periodically, and at predetermined time intervals, requesting updates of traffic information corresponding to the at least one traffic network from a plurality of sources; receiving updates of traffic information from the plurality of sources, including traffic information reported from at least one crowdsourcing probe, said traffic information comprising a current vehicle speed; with respect to at least one of the time intervals, aggregating the traffic information received from the plurality of sources; storing said traffic information as historical traffic data; with respect to at least one of the time intervals, utilizing stored historical traffic data as traffic information if no traffic information updates are available; and with respect to at least one of the road segments and at least one of the time intervals: establishing a default speed; determining traffic intensity, wherein determining traffic intensity comprises calculating road speed capacity, road speed capacity being equal to: ((default speed−reported speed)/default speed))*100; the reported speed comprising one of: a reported current vehicle speed, an aggregation of reported current vehicle speeds, a vehicle speed based on historical traffic data; recalculating road speed capacity, by a respective predetermined factor, in response to at least one of: an accident report, and a traffic light outage; providing a visual representation of road speed capacity for at least one user; and requesting at least one new crowdsourcing input based on predefined levels of road speed capacity.
