INTRODUCTION

The most common transport medium is road transport.

Safety becomes very important due to the increasing novehicles.

Setting up speed limits for vehicles is one way to preventaccidents.

Our project will force a speed limit onto vehicles which cmaximum speed limit of a particular zone.

ZigBee Technology

ZigBee is a communication protocol for Personal Area Networks(PA

The physical communication range is 10-100 meters.

Widely used in PANs due to low power requirements.

Simpler and less expensive than Bluetooth and Wi-Fi.

Data rate : 250 kbit/s

Operates in ISM Radio Band(ISM) 2.4 GHz worldwide.
