Traffic Lights require a communications solution to replace the existing EPS 42 communications made obsolete by BT’s move to 21CN exchanges. The technology is more than 20 years old and has become uneconomical. Mesh4G is a solution that not only fits the bill but can have a lower revenue cost than current technology, and in addition provides expansion for all street based communications without extra revenue requirements.
With this upgrade UK Councils have the unique opportunity to create wireless communication systems that cover whole cities.
- Fixed line costs can be reduced significantly by utilising the existing infrastructure.
- Enhanced service levels are provided to both the general public and council employees.
- Capital costs are lower than those for civil engineering work of typical UTMC systems, and with no revenue costs.
- RTI can be done with Mesh4G™ as it operates on moving vehicles. Bus Priority and Clear-Down issues are solved.
The scope of the Mesh4G™ Network can encompass RTI, car park counters, variable message signs, information kiosks, bus stops, ticket machines, Council workers, buses and CCTV. In the present wireless digital world, it is now possible to provide integrated communications for councils with no revenue component. With their physical infrastructure, Councils are in a very commanding position to install digital systems with a wireless infrastructure.
Traffic lights are not the only application to benefit from wireless; other areas are real-time passenger information, CCTV, parking ticket machines, variable traffic signs, Council workers, emergency services and schools.
With the introduction of Urban Traffic Management and Control systems (UTMC), there is a need to provide information from the traffic light controller back to the central server. Either this is an existing system, based on serial communications which requires replacement, or a new communications connection. In most cases the use of a wireless system has an equal or lower capital cost than an equivalent cabled solution (taking into account the required civil engineering). In addition, the wireless solution does not incur a revenue cost.
For UTMC-connected traffic lights, a communications path must exist back to the control centre. This can be accomplished by the use of Mesh4G™ Network clusters. Traffic lights are connected via Mesh Nodes to each other, and then via an Access Point back to the Network Control Centre.
Each Mesh Node provides an opportunity for other devices to route through it, either by direct connection or by a wireless connection from a nearby node. CCTV cameras for traffic monitoring can be easily and cheaply connected this way. In fact, connections for multiple cameras can be put in place at one junction.
