Wireless Road Traffic Signal System

This NEW “Wireless Road Traffic Signal System” is built with latest Technologies to ELIMINATE and to OVERCOME difficulties faced in the earlier versions like

• PHYSICAL CABLING Between the Poles.
• Road Trenching.
• Signal Failure during Power Supply failure.
• Synchronization between the junctions.
• Central Monitoring and controlling of all Junctions
• Difficult to relocate in case of rearrangement.
• Unstandard Time and Duration in a Sequence.
• HIGH POWER Consumption.
• More no. Of sequences to suit the traffic variations in a day at a single junction.

Key Assets In The System:

• Master Control Unit.
•  Slave Unit with Count Down Timers
•  RED, YELLOW & GREEN Lamps / Three in One Lamp
•  Solar Panels & Battery Backup at Master and Slaves for Green Power source.

UNIQUE FEATURES:

1. ELIMINATES Physical Cabling between all the poles and Road Trenching in a junction
   • Uses Zigbee Wireless Communication between all the poles to eliminate communication wiring
   • Solar Power Supply at each pole eliminates power supply wiring from one source (State Electricity Board).
   • No other cables / wires required to be laid across the junction. Hense eliminates the Road Trenching.
2. Easy to relocate in case of rearrangement.
   • Each pole uses Solar Power and Wireless Communication for Lamp Controlling. It is easy to relocate or rearrange them in case of road widening etc
3. WORKS even during the POWER SUPPLY FAILURES.
   • Uses BATTERY BACKUP for req. No. of hours, makes the system to work independent of Power Supply Failures.
4. Maintains Standard Time and Duration in a Sequence.
   • Time synchronization with GPS clock to maintain INTERNATIONAL & STANDARD Time & Time Duration in a Sequence.
5. Reduced POWER CONSUMPTION
   • Uses High Bright, focused and low power consumption LEDs in a lamps and COUNT DOWN timer for more reliability, longer view and longer life.
6. Synchronization between the junctions.
   • Possibility to maintain the Synchronized Sequences in a series of Junctions for a given speed between the junctions.
   • This helps to maintain the synchronization between the junc tions for Free Flow of Traffic.
7. Hour wise and day wise sequences in a week.
   • Provision to program HOURWISE in a day and DAYWISE in a week SEQUENCES to suit the TRAFFIC VARIATIONS in a JUNCTION.
   • Provision to program 20 Holiday Sequences.
8. Central Monitoring and controlling (optional)
   • Uses GPRS / GSM connectivity to upload the signal status ON-LINE to the central place.
   • Each junction reports all the failures to the central place. i.e.
   • Any Lamp permanent ON or OFF.
   • Power Supply Failures
   • Communication Failures etc
   • Mimic showing the functioning of Junctions OFFLINE to understand the synchronization and sequence operations.
9. Three in one Lamp
   • “RED, YELLOW & GREEN” arranged in one retrofit.
   • Cost effective.
   • Saves space and more safer from getting damaged.
