Traffic Signals Policy

Urban Traffic Control (UTC) is the method of coordinating traffic signals in a network by the use of timing plans loaded on a central computer. Timing plans that vary by time of day (for example to accommodate tidal flows associated with the AM and PM peaks) are automatically loaded by the computer and the timings on-street change accordingly.

SCOOT (Split Cycle Offset Optimisation Technique) takes information 'live' from on- street detectors and calculates the required timings for a series of closely associated junctions / crossings that will produce the least overall delay to traffic on the network covered.

Microprocessor Optimised Vehicle Actuation (MOVA) is a similar product used at an individual junction/crossing or signal controlled roundabout. Again, MOVA utilises additional traffic signal loops cut into the carriageway further away from the stop line linked to the signal controller. It continually adjusts the green time required for each approach by assessing the number of vehicles approaching the signals, whilst at the same time determining the impact that queuing vehicles would have on the overall operation of the junction.

The UTC inventory information is also held by MBC, this includes information on SCOOT and MOVA sites, BT and other communications information.

The Urban Traffic Management and Control System (UTMC) was introduced in 2012 in response to the Traffic Management Act, and includes assets such as Variable Message Signs (VMS), traffic management and CCTV enforcement cameras, car park spaces live information, communication equipment and the MOVA / SCOOT systems, covering all five Tees Valley Authority areas. UTMC systems are designed to allow the different applications used within modern traffic management systems to communicate and share information with each other. The idea behind UTMC is to maximise road network potential to create a more robust and intelligent system that can be used to meet current and future management requirements.
