A road is a thoroughfare, route, or way on land between two places that has been surfaced or otherwise improved to allow travel by foot or some form of conveyance, including a motor vehicle, cart, bicycle, or horse. Roads have been adapted to a large range of structures and types in order to achieve a common goal of transportation under a large and wide range of conditions. The specific purpose, mode of transport, and location of a road determine the characteristics it must have in order to maximize its usefulness. Following is one classification scheme.

System and method for processing and displaying traffic information in an automotive navigation system

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.

Vehicle-autonomous detection of traffic backup

A process for automated vehicle-autonomous detection of a particular traffic situation by continuously detecting an instantaneous vehicle speed onboard a vehicle. The detected vehicle speeds are classified using guidelines which may be based on rigid values or on fuzzy logic relationships, into one or more of a plurality of traffic categories by assigning a weight for that detected vehicle speed to each of the traffic categories. Thereafter, for each traffic category the weights associated with the detected speed values are integrated over time to calculate an integrated result for each traffic category. The integrated results of the traffic categories are then evaluated based on predetermined rules or criteria to generate a probabilistically-based traffic detection value indicating the traffic category representing the vehicles' current traffic situation. The traffic categories and guidelines or membership functions or relationships are defined for use with a particular type of road.

Mobile track vehicle

An improved self-propelled mobile track vehicle (MTV) capable of traveling by road at normal highway speeds and traveling by rail after conversion at a narrow railroad crossing by producing a device for rotating the vehicle 90 degrees. The vehicle is powered by a diesel engine driving through a power shift transmission to the roadway and railway axles. A significant advantage over other types of road / rail vehicles is that 100 percent of the vehicle's weight is carried on the rail wheels, which are powered and braked, thereby allowing higher and safer rail speeds. One way to convert the vehicle from roadway travel to railway travel is to maneuver it into a position parallel to the track at a road crossing. The rail axles are then extended and road axles retracted. In addition, a turntable mounted at the vehicle's center of gravity also allows the vehicle to convert at a narrow road crossing. While at railway / roadway crossing the unit raises and rotates 90 to align with the desired roadway or railway. The vehicle can assist in starting a train by extending the powered road axle so that the inner rubber tires contact the rail and the high traction of rubber on rail assists in increasing starting traction of the vehicle thus allowing the vehicle to assist in starting a train.
