Patent ID: 8730059

Claim:
A method of vehicular traffic management, comprising: a computer system receiving, form devices distributed in a plurality of roadway segments of a physical roadway system including multiple intersecting roadways, real-time traffic information individually describing vehicular traffic in each of the plurality of roadway segments; prior to the receiving, simulating traffic flow in the physical roadway system under a variety of traffic and weather conditions utilizing a simulation model of the physical roadway system and storing simulation results obtained by the simulating, wherein the simulation results include interrelationships of traffic speeds and volumes between roadway segments disposed in different ones of the multiple intersecting roadways; the computer system determining from the real-time traffic information and the stored simulation results an advised speed for a particular roadway segment in a particular roadway among the multiple intersecting roadways, wherein the determining includes determining the advised speed for the particular roadway segment based on real-time traffic information from at least one other roadway segment in another of the multiple intersecting roadways and the interrelationships from the simulation results; the computer system modifying a vehicle occupancy requirement of a high occupancy vehicle (HOV) lane spanning one or more of the plurality of roadway segments based on the real-time traffic information and the stored simulation results; and the computer system transmitting, via a communication network, a speed advisory command specifying the advised speed to a device in the particular roadway segment for presentation.
