Traffic signal upgrades for Crownhill Road

We’re upgrading signals on Crownhill Road to help improve traffic flow and reduce carbon emissions.

Work to install new MOVA (Microprocessor Optimised Vehicle Actuation) signal controllers at the Budshead Road junction will get under way on Monday 5 February. A similar upgrade will start at the Transit Way junction on Monday 26 February.

MOVA is smarter than other systems, in that it can monitor the number of vehicles approaching from further away and assess the impact that queuing vehicles will have on a junction. This means it can continually adjust the ‘green time’ for each approach in a more intelligent and responsive way.

MOVA units can 'learn' regular traffic movements, which can be particularly useful in locations where traffic conditions vary considerably depending on the time of day, day of week or even season. They can also communicate with MOVA units at other junctions along the same route.

Councillor Mark Coker, Cabinet Member for Strategic Transport and Planning, said: “We have made it a priority to reduce traffic congestion and carbon emissions in Plymouth and replacing our ageing systems with more intuitive technology like MOVA means we can ensure our signals perform more efficiently.

“We’re not just upgrading the signal controllers as part of this work; we’re also installing new extra low voltage equipment, which reduces our electricity costs and replacing signal heads and poles, helping to improve the overall resilience of our road network.”

Each junction upgrade is expected to take around three weeks. Temporary signals will be used during the works but will be manually controlled to help minimise disruption. We apologise for any delays and thank people for bearing with us during these works.
