| 摘要： | The purpose of this demonstration project is to test the concept of using cellular wireless technology to monitor and control traffic signal systems instead of hardwired communications lines. The specific wireless technology deployed is called Cellular Digital Packet Data (CDPD), which provides wireless Internet Protocol (IP) data communications between the traffic signal controllers and the central computer through a cellular service provider. The test bed for this project was chosen to be in the area of San Pedro, California where the Los Angeles Department of Transportation (LADOT) has no hardwired interconnect. The location of this test bed is about 25 miles south of the downtown Traffic Management Center (TMC). The San Pedro area is ideal for this specific test since it is so far from the central TMC. A total of 36 intersections were chosen as part of this project. As of today, 26 intersections are on-line via CDPD. The 2070 timers are chosen for this project for its faster communication rate over the 170. The remote intersections with the 2070 timers are polled once every 5 seconds. |
