Mobile VMS were part of a collaborative multi-provider team working to deliver a safe 60mph speed limit through roadworks on the M4J3-12 smart motorway scheme.  This was part of a wider programme to improve the customer experience of roadworks. Mobile VMS diligently supported the development of an innovative smart traffic management solution integrating alerts from a stopped vehicle detection system directly into portable VMS to alert drivers of potential obstructions in the road ahead.
