System and method for improving traffic flow

A technique facilitates the flow of traffic along highways by placing sensor devices within vehicles traveling along a highway. A sensor device within a first vehicle is able to detect whether the vehicle immediately ahead is increasing or decreasing the distance back to the first vehicle. The driver of the first vehicle is notified of the increasing or decreasing distances through simple indicators that enable the driver to take corrective action more appropriately than otherwise possible. The sensor device and indicators reduce driver overreaction that can result in standing wave traffic patterns, traffic congestion, wasted fuel and wasted time. Additionally, the system can be designed to integrate information from multiple users to enable coordination of movement among motor vehicles to improve overall traffic speed in a given line.
