A method and system for controlling the flow of vehicle traffic. The system of the invention includes a grid of one-way streets, and a one-way ramp near each street intersection. Each ramp allows only a right-turn at an intersection. Preferably, each intersection is an overpass intersection, so that each street directs vehicles not making a right-turn at an intersection over or under the intersecting street. Preferably, the system also includes a traffic monitoring subsystem, including one or more velocity sensor stations positioned along the streets, and a processor for processing the output of each velocity sensor station to determine the average speed of vehicles translating past the velocity sensor station. Preferably, each velocity sensor station includes at least two magnetic sensors embedded in the street surface. Each magnetic sensor outputs a signal in response to proximity of a passing vehicle. An average vehicle velocity is determined from one or more sets of sensor output signals, each set generated in response to a different vehicle. Preferably, a velocity sensor station is provided downstream of each ramp, average velocity signals are generated from several velocity sensor stations positioned at consecutive identically-directed streets and are converted into form for display, and the converted signals are displayed on a display device mounted along a first street intersecting the identically-directed streets, to enable one in a vehicle translating along the first street to make an intelligent decision about which of several consecutive right turns to take.

A vehicle traffic system comprising: a plurality of intersecting one-way streets which form a grid, each intersection of the one-way streets being in the form of an overpass; and a plurality of one-way ramps, each ramp providing a path for a vehicle moving along one of the one-way streets to make a single type of turn onto another one of the one-way streets forming an overpass intersection with the one of the one-way streets, each ramp providing a path for the same type of turn as provided by all of the other ramps; a traffic monitoring subsystem, wherein the traffic monitoring subsystem includes: a first velocity sensor station mounted along a first one of the one-way streets, first processing means for processing output signals from the velocity sensor station to generate a first velocity signal indicative of an average speed of at least one vehicle translating past the velocity sensor station; a second velocity sensor station mounted along a second one of the one-way streets, where the second one of the one-way streets does not intersect the first one of the one-way streets; second processing means for processing output signals from the second velocity sensor station to generate a second velocity signal indicative of an average speed of at least one vehicle moving past the second velocity sensor station, wherein the first processing means is programmed for generating a first display signal for controlling display of a representation of the first velocity signal, and the second processing means is programmed for generating a second display signal for controlling display of a representation of the second velocity signal; and a display device for receiving the first display signal and the second display signal, and displaying in response the representation of the first velocity signal and the representation of the second velocity signal.
