A system for instantaneously monitoring traffic congestion including a plurality of monitoring electronic devices located in motor vehicles traveling on roadways in a selected region. Each monitoring electronic device is coupled to a GPS receiver that provides physical location to a wireless modem capable of connecting to a wireless communication network. The system also includes a central computer connected to a wide area network that is able of continuously downloading physical location information from a plurality of monitoring electronic devices also connected to the wide area network. The central computer uses a traffic monitoring software program and a mapping database containing roadway information for a region and the movement information from the monitoring electronic devices to create a continuously updated traffic congestion database. Authorized users of the system are able to log onto the central computer to a portion of the database that contains specific traffic flow and congestion information. Using the system, users are also able to obtain estimated times of arrival for a specific trip, and recommendations on alternative route information. The system can also take into consideration current or anticipated events that may affect traffic congestion.
A vehicle communication system is provide with a host vehicle two way communication device, an omni-directional antenna, a bi-directional antenna, a vehicle positioning component, a vehicle map component and at least one of a vehicle broadcast power modulating component and a bi-directional antenna aiming component. The vehicle map component includes road data with roads being classified by at least one of a road segment attribute. The vehicle broadcast power modulating component selectively varies broadcast power of the omni-directional antenna and broadcast power of the bi-directional antenna based on a road segment attribute of a road on which the host vehicle is traveling on as determined by the vehicle positioning component. The bi-directional antenna aiming component aims the bi-directional antenna based on at least one of traffic information received by the communication device and the road segment attribute of the road on which the host vehicle is traveling on.
A system, a method and computer-readable media for presenting dynamic traffic information. A user profile is stored, and advisory data based on the user profile is gathered. The advisory data may include traffic information associated with road segments identified by the user profile. Upon receiving a user input, the advisory data is presented to a user.
A method and system for modeling and processing vehicular traffic data and information, comprising: (a) transforming a spatial representation of a road network into a network of spatially interdependent and interrelated oriented road sections, for forming an oriented road section network; (b) acquiring a variety of the vehicular traffic data and information associated with the oriented road section network, from a variety of sources; (c) prioritizing, filtering, and controlling, the vehicular traffic data and information acquired from each of the variety of sources; (d) calculating a mean normalized travel time (NTT) value for each oriented road section of said oriented road section network using the prioritized, filtered, and controlled, vehicular traffic data and information associated with each source, for forming a partial current vehicular traffic situation picture associated with each source; (e) fusing the partial current traffic situation picture associated with each source, for generating a single complete current vehicular traffic situation picture associated with entire oriented road section network; (f) predicting a future complete vehicular traffic situation picture associated with the entire oriented road section network; and (g) using the current vehicular traffic situation picture and the future vehicular traffic situation picture for providing a variety of vehicular traffic related service applications to end users.
Disclosed herein are systems and methods for exchange of travel data in a roadway information system associated with a first roadway vehicle and a second roadway vehicle. In one embodiment, the roadway information system may comprise, for example, a first mobile client system associated with the first roadway vehicle, a second mobile client system associated with the second roadway vehicle, a wireless communication network, and a processing system communicatively coupled to the wireless communication network. The first mobile client system may deliver first travel related data to the processing system via the wireless communication network. The processing system may deliver second travel related data to the second mobile client system via the wireless communication network, where the second travel related data relates at least in part to the first travel related data.
A method for providing traffic information concerning one or more specific sections of a route to a traveler includes the steps of generating a bundle of traffic advisory messages for the traveler when an event relevant to the traffic situation has occurred in an affected section of the highway, wherein each of the traffic advisory messages present in the bundle of traffic advisory messages describes the traffic-relevant event in question at a different time within a defined interval and selecting a relevant message from the bundle of traffic advisory messages which is valid at a time relevant to the traveler.
