Overview
Background & policy context:
The current architecture of traffic control systems includes the following elements:
- Power supply,
- Central unit,
- Output control,
- Detectors,
- Auxiliary elements.
Nowadays, all these elements are placed together in a single board. This situation implies that all the power wiring to the traffic signals, detector devices, magnetic loops etc. have to be connected in the same reduced space, making the installation difficult.
Objectives:
The REGENT project tackles the development of a distributed control system, where the different components can be located in different places.
Among the advantages of the new architecture proposed are:
- The control of each of the exits can be located next to the traffic light, avoiding extra wiring;
- The detector can be also distributed, and it is not necessary to introduce the wires coming from the magnetic loop into the control system;
- The auxiliary inputs can be connected directly to the input drivers;
- Each output is only responsible for one or a few lamps, improving the accuracy of the measures and control;
- The size of the board can be reduced.
Methodology:
For this project the usual phases of design and development of hardware and software systems are followed:
- User requirements;
- Software architecture design;
- Software architecture detailed design;
- Software implementation;
- Operation and maintenance of the software;
- Hardware architecture design;
- Hardware architecture detailed design;
- Hardware implementation.
