Rushall junction (A461) improvements: Information for consultation - Traffic signals, lighting, road marking and air quality
Intelligent traffic signals
What is proposed
The traffic signals at the junction will be upgraded to use intelligent traffic signal technology.
What this means
- Instead of running to fixed signal timings, the signals will respond to real traffic conditions.
- Sensors in the road detect vehicle queues and traffic demand on each approach.
- The signals then automatically adjust how long each green light lasts to suit the amount of traffic waiting.
Why this change is needed
- Traffic levels vary throughout the day, and fixed signal timings cannot respond to this.
- This technology allows the junction to adapt to busy and quieter periods, helping traffic move more efficiently.
What benefits this delivers
- More vehicles can pass through the junction on each green signal, increasing overall capacity.
- Reduced queuing and delay, particularly during peak times.
- Smoother traffic flow and fewer stop‑start movements.
- Improved reliability for buses and general traffic.
How this will be delivered
- Existing traffic signal equipment will be fully replaced and upgraded.
- No additional land is required to introduce this improvement.
- The system operates automatically and continuously adapts to traffic conditions.
How does this help to reduce red light runners
An intelligent traffic signal upgrade helps reduce red‑light running mainly by making signals feel fairer and more predictable, rather than just stricter.
Upgraded street lighting
Upgraded‑LED street lighting across the junction will improve visibility for all road users, making it easier to see pedestrians, cyclists, vehicles and signs, particularly during hours of darkness and poor weather.
LED lighting provides a more even and brighter light compared to older lamps, helping to improve safety and reduce the risk of collisions. It is also more energy‑efficient and reliable, meaning lower maintenance requirements and fewer outages.
A full revised lighting design will be carried out to inform this upgrade and ensure lighting levels are appropriate for the junction layout and use.
Revised road markings, lining and signage
New road markings, lining and signage will be introduced to improve driver understanding of how to navigate the junction.
Clearer advance warning signs and lane markings will help road users position themselves in the correct lane earlier, reducing last‑minute manoeuvres, confusion and the risk of collisions.
This will contribute to smoother traffic flow and a safer junction for all users.
Air quality
Intelligent traffic signals improve air quality by reducing unnecessary stopping, queuing and idling.
- Less waiting at red lights
Intelligent signals detect real traffic conditions and only hold vehicles on red when needed. Fewer vehicles sitting still with engines running means fewer exhaust emissions. - Smoother traffic flow
By adjusting green times to match demand, traffic moves through the junction more efficiently. Vehicles spend less time accelerating from a stop, which is when emissions are highest. - Reduced congestion and queuing
When queues are shorter, vehicles clear the junction more quickly. This reduces the build‑up of pollution around busy roads, shops and homes. - Supports walking and cycling
By improving crossings and reducing delays, intelligent signals make it easier for people to choose to walk or cycle, which further reduces traffic‑related emissions over time.
