Innovative Congestion Control System


The main aim of this project is to build a system in which the signaling time at traffic signaling junction will be controlled according to the availability of ambulances.


The purpose of this project is to implement an automated system for clearing the traffic for ambulances to help the people who met with accidents or the people who are in emergency conditions without any disturbance or delay


According to this project, it employs 3 sections, one is placed at traffic signal junction and the other two sections placed in two different Ambulances. The sections placed in the ambulance contains 5 switches for the operations Emergency, Normal , out, direction 1 and direction 2.

So according to this project, whenever the ambulance is yet to reach a traffic signal junction, the concerned person need to press the switches like Emergency / Normal priority and direction 1 / 2 informing the direction and priority of ambulance reaching the signal junction. The other section placed at traffic signal receives the information and takes the control action according to the priority. The control action is in the form of timing for Green lights. If both are of high priority i.e. Emergency then the one who pressed first will be given priority.

The communication between the sections is done using Zigbee technology. Each and every section is designed around a microcontroller as a control unit. The Zigbee module is interfaced to microcontroller


Now a day's every system is automated in order to face new challenges. In the present days Automated systems have less manual operations, flexibility, reliability and accurate. Due to this demand every field prefers automated control systems. Especially in the field of electronics automated systems are giving good performance. And this is realized by making use of Zigbee technology for communication. Zigbee is new wireless technology guided by IEEE 802.15.4 Personal Area Network standard. It is primarily designed for the wide ranging controlling applications and to replace the existing non-standard technologies. It currently operates in 868MHz band at a data rate of 20Kbps in Europe, 914MHz band at 40kbps in USA , and the 2.4GHz ISM bands Worldwide at a maximum data-rate of 250kbps.

By this project we can implement an automatic traffic clearing system for ambulances and can provide medical support to the people with in time who are in critical conditions and can save their lives.
