Centralized facility and intelligent on-board vehicle platform for collecting, analyzing and distributing information relating to transportation infrastructure and conditions
ActiveUS20050065711A1Effectively conditionEfficient designAnalogue computers for vehiclesInstruments for road network navigationTransportation infrastructureIn vehicle
An on-board intelligent vehicle system includes a sensor assembly to collect data and a processor to process the data to determine the occurrence of at least one event. The data may be collected from existing standard equipment such as the vehicle communication bus or add-on sensors. The data may be indicative of conditions relating to the vehicle, roadway infrastructure, and roadway utilization, such as vehicle performance, roadway design, roadway conditions, and traffic levels. The detection of an event may signify abnormal, substandard, or unacceptable conditions prevailing in the roadway, vehicle, or traffic. The vehicle transmits an event indicator and correlated vehicle location data to a central facility for further management of the information. The central facility sends communications reflecting event occurrence to various relevant or interested users. The user population can include other vehicle subscribers (e.g., to provide rerouting data based on location-relevant roadway or traffic events), roadway maintenance crews, vehicle manufacturers, and governmental agencies (e.g., transportation authorities, law enforcement, and legislative bodies).

InactiveUS20060055565A1Analogue computers for vehiclesArrangements for variable traffic instructionsDisplay deviceTraffic flow
A system and method for displaying traffic information in an automotive navigation system having a display, memory and a data receiver. The method includes the first step of storing in a traffic speed table in memory at least two speed threshold limits wherein each speed threshold limit represents a different traffic flow category. The receiver receives data representative of the vehicle speed on at least one road segment and compares that received vehicle speed data with the traffic speed table to determine the traffic flow category corresponding to the received speed data for the road segment. A visual indicator is then displayed on the display which corresponds to the traffic flow category for the road segment. The user is able to customize the speed threshold limits through a GUI. These speed threshold limits are further user modifiable as a function of weather, day of the week, road conditions, type of road, as well as other factors.
