In implementation four TC QT50 vehicle,counter sensors are mounted on the TLCof. every SJ and are pointed towards eachlanes,say L1 L2 L3 L4 The sensorsare given a.
view say V1 V2 and distance say D 40m to, sense vehicles from that particular view up to the. given distance Then the sensor is wired to,connect to the ES which is placed on the TLC of. each SJ so that it can receive the count,information say C1 C2 C3 C4 for every lanes. for every particular junction,ES is composed with GSM and. Microcontroller so that the processed,information from Microcontroller can be.
communicated via GSM to and fro the server, Fig 8 Signaling based on Emergency Services GSM interconnects all the SJ to the server. Therefore after collecting the count information, C Connection Management System system will compare and sort the count in. Connection management includes wired and descending order Lane which have the highest. wireless connection Wired connection is made count will get the Green signal first and the next. between sensor and TLC to send the count and highest the Yellow signal the next Red signal. wireless is made through GSM between TLC to and so on ending up with pedestrian walk A. Server which in turn to vehicles SJ s and ASJ s time period say T 2min is maintained for each. and emergency services to server for sending shift from one signal to another Finally after a. warning signals as shown in Fig 9 cycle the system will be resumed and restarted.

ISSN 2229 5518, Then the ES sum up the counts for every SJ the adjacent junctions as they are notified about. with its SJ name say the congestion by the server through GSM.
