I NTELLIGENT T RANSPORTATION S YSTEMS

I NTELLIGENT T RANSPORTATION ENABLES ELEMENTS WITHIN THE TRANSPORTATION SYSTEM — VEHICLES, ROADS, TRAFFIC LIGHTS, MESSAGE SIGNS, ETC.— TO BECOME INTELLIGENT BY EMBEDDING THEM WITH MICROCHIPS AND SENSORS AND EMPOWERING THEM TO COMMUNICATE WITH EACH OTHER THROUGH WIRELESS TECHNOLOGIES.
