Abstract
Abstract A smart traffic control device transmits information to approaching vehicles regarding its current and future state enabling vehicles to control their speed to avoid arriving at the traffic control device until it permits the passage of traffic, thus avoiding stopping, idling and reaccelerating when reaching the traffic control device. In other embodiments the traffic control device or systems receives information from vehicles, transmitting it to other vehicles.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
180 words
A traffic management method, the method comprising the steps of a) providing at least one traffic control device having; i) means to determine the location and speed of a plurality of approaching vehicles, ii) means to transmit at least a recommended speed to at least a portion of the plurality of approaching vehicles, b) providing a plurality of vehicles having; i) means to communicate with the traffic control device, ii) wherein said at least one traffic control device and at least a portion of said plurality of vehicles has a means to calculate means to determine the future position of the vehicles as they approach the traffic control device based on their speed, c) directing a first subset of the plurality of vehicles to increase speed, d) directing a second subset of the vehicles to decrease speed, e) whereby the fist and second subsets of vehicles are separated into spaced apart first and second pods of vehicles for which at least a portion of the vehicles in each pod accelerate or decelerate to approach a common speed in each pod.
Claim 2
Dependent Claim
180 words
A traffic management method, the method comprising the steps of a) providing at least one traffic control device having; i) means to determine the location and speed of a plurality of approaching vehicles, ii) means to transmit at least a recommended speed to at least a portion of the plurality of approaching vehicles, b) providing a plurality of vehicles having; i) means to communicate with the traffic control device, ii) wherein said at least one traffic control device and at least a portion of said plurality of vehicles has a means to calculate means to determine the future position of the vehicles as they approach the traffic control device based on their speed, c) directing a first subset of the plurality of vehicles to increase speed, d) directing a second subset of the vehicles to decrease speed, e) whereby the fist and second subsets of vehicles are separated into spaced apart first and second pods of vehicles for which at least a portion of the vehicles in each pod accelerate or decelerate to approach a common speed in each pod.
Claim 3
Dependent Claim
48 words
The method of claim 1 further comprising the step of adjusting the time of the traffic control device wherein each of the first and second pods can pass through the intersection at their respective speeds without a significant change in speed or speed range associated with each pod.
Claim 4
Dependent Claim
25 words
The method according to claim 1 wherein the vehicles in the first and second subsets are approaching the traffic control device on the same road.
Claim 5
Dependent Claim
21 words
The method according to claim 2 wherein the traffic control device halts traffic between the first subset and the second subset.
Claim 6
Dependent Claim
24 words
The method according to claim 4 wherein the traffic control device halts traffic traveling in the same direction as the first and second pods.
