Traffic Signal Control

The Engineering Design Group can provide a complete traffic signal design service for both the public and private sector clients. Traffic levels are continuously increasing yearly and expectations from stakeholders are higher to reduce the delays and congestion.  This requires innovative solutions and application of new technologies to solve the challenging traffic problems.  Our traffic signals team has the right skills and expertise to provide the best solution. They deal with isolated junctions to complex high volume signalised roundabouts using industry standard software packages for detailed computer modeling. In addition, the team also designs, authorises and oversee all multi-phased temporary traffic signals in the County. All work is carried out in accordance with our Quality Assured procedures.

Our services include

  • Traffic signal junction design – from feasibility to detailed design and site supervision.  Our experience includes designing a wide range of layouts from simple to complex multi-stream junctions.
  • Controller specifications – the team has a considerable experience of writing controller specifications and carrying out factory acceptance tests.
  • Pedestrian/Cycling crossing design – pelican and toucan crossing designs, including assessment of suitability of site locations.
  • Design checks – auditing support for traffic signal layouts is provided to the in-house development control team.  Signal schemes relating to approved planning applications are supervised by our highly skilled team.
  • Junction calculations – we can undertake calculations using unique spreadsheets, lane flow diagrams, LINSIG, TRANSYT and PARAMICS.
  • Tendering – we can also undertake the preparation of tender documentation with regard to signal installations.
  • MOVA – we have a wide range of experience in setting and validating this traffic responsive system at isolated junctions.

Examples of our recent commissions

Foxhunter Roundabout
(B4114 Leicester Rd./B582 Enderby Rd.)
 Developer contributions were used to upgrade this this roundabout to allow for extra lanes and better crossing facilities for pedestrians and cyclists. SCOOT technology was applied together with a unique system of staging. These alterations have resulted in a substantial improvement in the peak period congestion and has reduced ‘rat-running’ through unsuitable residential roads.

Ashby-de-la-Zouch
B587 Nottingham Road / Dents Road Improvements
 This commission was from developers of a retail park off Nottingham Rd. The team was required to carry out the detailed design and site supervision. MOVA technology was applied to this staggered double junction with pedestrian facilities. This multi-staged complex junction is highly effective in handling the traffic levels at this busy junction in Ashby. Traffic Signals on the B587
Birstall Hallam Fields This commission was from a consulting engineer acting as agents to a developer. The work involved designing three new junctions between A46 Western Bypass and Bentley Road. Upgrading the A6/Greengate Lane junction to a double signal controlled junction was also part of the commission. All the junctions were then operated under the SCOOT system. This allows the junctions to be controlled and coordinated to reduce the delays along the A6. Traffic signals on A6 at Birstall
