• The present invention discloses a  traffic control system implemented at a multi-phase intersection, comprising of :

A processor:

• Process or executes instructions stored on a non-transitory machine-readable storage medium and the hardware

A traffic state estimation module:

• Receive a first set of vehicle attributes corresponding to a plurality of vehicles from sensors and estimate arrival flow, delay, queue length

• The first sensor is positioned at an upstream point and a second sensor positioned at a downstream point on a first leg of a plurality of legs of a multi-phase intersection respectively
• A measure of time stamp differences of the plurality of vehicles may be determined.
• The system calculates traffic states from these sampled travel time data.

Shock Wave Speed Calculation:

• Traffic Estimation Module receives data from two sensors located at different points on the same road segment.
• Further, calculate the shock wave speed, which reflects variations in the time it takes for vehicles to cross the intersection.

1. The first set and the second set of time stamped vehicle attributes comprise one of a device identifier and a location of one of a plurality of electronic devices associated with the corresponding vehicle.
2. The first sensor and the second sensor is one of a Wi-Fi MAC sensor, RFID sensor, or a Bluetooth sensor.
