Abstract:
The congestion of the road today becomes an important challenge for densely populated
cities like Dhaka, Bangladesh. Emergency response vehicles are one of the main services
affected by road delays (e.g. ambulances, fire trucks). This thesis has been developed on
traffic system analysis with preference for emergency vehicles by controlling the traffic
signals to smooth the traffic flow for emergency vehicles. The RFID (Radio Frequency
Identification) technology used to link wirelessly the traffic signals & emergency vehicles
together. The main concept behind the suggested system is that whenever an emergency
vehicle comes to a standstill owing to significant traffic congestion, RFID placed at the traffic
signal (receiver) recognizes the RFID tagged vehicle (transmitter) and communicates the
information to the microcontroller. The controller IC in this case controls the traffic light
based on the data received from the receiver. The signal is then turned Green for a short
period until the vehicle passes past it, at which point it reverts to its normal signaling
sequence. This technology delivers commands to the microcontroller to control the traffic
lights and shorten response times during emergencies. It also serves as a mission to save
lives. There are currently no proven adaptive algorithms, which could give emergency
vehicles priority in Bangladesh. This analysis can also draw a valuable lesson for the setting
of signals for emergency vehicles and to enable traffic technicians to establish effective
emergency signal timing plans. Here I tried to show that how effectively the delays reduced
by using this technology with some realistic collected data from different traffic scenarios.
