LED Display System for BUS / Automotive

Integrated Intelligent Transport System for Smart Cities

System Overview

The KPL ITS System is an integrated solution designed for Smart City Bus Systems. Our On-bus PIS System is Audio and GPS enabled, capable of sending real-time information to the backend server.

  • Real-Time Data: The backend server holds master data of all Buses and Bus Stops, processing real-time vehicle locations.
  • ETA Updates: The server calculates and sends Estimated Time of Arrival (ETA) to Bus Stop Displays.
Reliable After Sales Service

Kristronics provides nationwide support through a dedicated service network. We ensure timely servicing by maintaining an effective ratio of spare parts and engineers to installed systems.

Kristronics LED Displays

Kristronics LED Displays are used for the display of route number and destination texts. The Displays are designed from a user friendly perspective. Text and graphics are created by using the Mobitec editing software, and routes & data on the displays are controlled by Driver control Unit. These LED displays, together with our complete product range, provides the complete information systems designed for the demanding vehicle environment.

Zero Maintenance

  • The Displays are fully electronic with no moving parts.

  • IP- 65/66 design.

  • LED’s which will function for the normal lifetime of the bus.

  • The LED’s have built in UV protection which means they will keep their colour and intensity.

Optimal Legibility

  • High Bright Day Night viewable amber LED’s with a wide viewing angle.

  • Automatic Brightness control.

  • High resolution allows for more and longer text lines, and better fonts.

  • Multilingual Support

  • Text designs can be adjusted to give optimal legibility.

Easy Installation

  •  The Displays uses MS/aluminium to create a light weight, but solid construction.

  •  Installation is easier because of a thin depth dimensions.

  •  Displays are supplied with built in fixing points and cables fitted with connectors for a flexible and easy installation.
