1. A traffic management method that employs a traffic control device, the method comprising:
determining the locations and speeds of a plurality of vehicles; and
transmitting recommended speeds to at least some of the vehicles, the recommended speeds including
a. a first speed for a first subset of the vehicles that causes at least a first vehicle in the first subset to change speed and
b. a second speed for a second subset of the vehicles that causes at least a first vehicle in the second subset to change speed;
the transmitted recommended speeds being such that vehicles are instructed to accelerate or decelerate so that the first and second subsets of vehicles are separated and spaced apart in first and second pods of vehicles and such that the vehicles in each pod travel at a common speed, and
the transmitting recommended speeds comprising
a. instructing at least one of the first subset and the second subset to stop at a specified distance from an intersection and
b. providing to the subset that is stopped a recommended intersection approach speed and instructing vehicles in the stopped subset to accelerate prior to a traffic signal device changing from a stop signal to a go signal.
