Delivering Design for the £26.6m West Midlands Urban Traffic Control (UTC) Major Scheme
telent is the appointed Project Manager of the £26.6m West Midlands Urban Traffic Control (UTC) Major Scheme. The scheme is designed to reduce congestion in the West Midlands Metropolitan Highway Network by linking, for the first time, each of the Region’s existing UTC centres together so that they can share Information, Command and Control capabilities including Incident Management Strategies, video images, traffic data etc.
The West Midlands UTC Major Scheme covers Birmingham, Coventry, Dudley, Sandwell, Solihull, Walsall and Wolverhampton.
Design Services within the WMUTC scheme
Design services started to work on the scheme in June 2011, providing traffic signal design to the majority of the authorities within the scheme.
telent has undertaken traffic signal designs for the following areas: West Sussex CC, Cumbria CC, Gloucestershire CC and the Isle of Man Government
Scope of Works
telent provided the scheme with traffic signal designs including the provision of site drawings in AutoCad™ format, TR2500 traffic signal specification forms as well as SCOOT / MOVA design and validation. The design services team within telent have also been instrumental in the testing and evaluation the VISSIM models produced by TRL for the scheme.
Existing junctions have been up-graded to have dual SCOOT / MOVA control which provide the authorities the ability to switch between control strategies depending on traffic conditions. telent undertook the initial site evaluations defining the work requirements to facilitate the introduction of SCOOT and MOVA control. The assessment was based around the existing ducting and the controller, in general the ducting did not fully meet the standards required and additional duct designs were produced. The majority of the controllers were replaced which facilitated new TR2500 specification forms to be written.
TRL were commissioned to produce VISSIM models for strategic routes across the West Midlands as part of the scheme evaluation process, telent were commissioned to assist in the testing and evaluation of the models, prior to final acceptance by the authorities. telent evaluated the models which included testing the controllers within the scheme that are run under SCOOT or MOVA control.
The initial programme of testing and evaluation was undertaken by telent for each authority, covering the AM and PM peaks. telent worked closely with TRL in producing representative AM and PM models for each of the seven authorities. The strategic routes modelled under the scheme were split into sub sections which produced 90 models in total.
Following the initial testing and evaluation undertaken by telent a further programme of testing with the authority’s representatives present was also undertaken at TRL.
Design Approach and Standards
For the signals design element of the scheme, telent worked with the authorities in providing designs that fully meet the requirements of the scheme, working with the authorities enabled the programme to be completed on time and within budget. All designs are to current standards.
telent has strong project management skills and delivers turnkey projects using a single point of contact for the customer approach. The work and processes that we undertake in providing this programme of works include:
- Scoping of the works
- Site visit and design
- Local authority approvals
- Traffic management planning
- Design of the civils work
- Installation & commissioning
Each site and each authority had individual and specific requirements, with the general requirement to provide dual SCOOT and MOVA control. The designs took into account such elements as listed below:
- Existing ducting quantity and locations
- Existing control strategies
- Carriageway condition
- Footway condition
- Controller condition
Some of the designs required additional ducting and new controllers. Working with the authorities enabled some additional changes to be made to the controllers to give the authorities additional control flexibility.
