The A77 Bellfield Interchange south of Glasgow allows traffic from the A77, A71 and A76 to merge and change direction. Being the interchange between these key routes means the junction is prone to congestion, especially during rush hour.
Queues on the exit slip road on the A77 are common and although signs were installed on the approach to the slip road, warning drivers that queues were likely, these static signs showed no effect on driver behaviour.
Near misses were common place, especially when the queuing traffic extended beyond the slip road onto the mainline A77. Police Scotland were concerned over this risk and asked Scotland TranServ to provide a solution that would reduce such incidents.
Through extensive experience designing route safety solutions Clearview Intelligence know that sharing information on what is happening on the road ahead with drivers in real-time is an effective way of influencing their behaviour. Drivers quickly get used to static signage and fail to notice it. In contrast, signage that changes in response to what is happening on the road ahead helps drivers to stay attentive to the warnings. It was therefore agreed that a solution that combined vehicle detection with dynamic signage would help drivers to approach queuing traffic with caution and avoid rear end shunt accidents.
Clearview designed a solution that detects queueing traffic in two locations: one at 50m on the slip road and another where the A77 joins the slip road. Inductive loops provide the vehicle detection information into the Clearview Intelligence Smart Junction Controller, which activates a relevant warning message on the signs. When traffic queues on the slip road and reaches the first detection location the warning sign closest to the slip road is activated to display an “On Slip” message. As traffic builds and reaches the main carriageway, the second sign is also illuminated and both feature the warning message: “Queues Ahead”.
Presenting drivers with information on what is happening on the road ahead in this way helps to capture their attention and allows them to respond safely to building traffic.
Working with Clearview allows us to produce site specific solutions to problems. Having used them on several schemes in the recent past they are part of the team. This scheme will provide a solution to a high risk problem, giving drivers live information of the formation of the queue allowing them to take appropriate action, reducing the risk of any collisions.
The A50 is a strategic east to west connection between the M6 and M1
The Stoneferry Corridor is a primary route originating north of Hull, with strategic connections to the Port of Hull, City Centre, and Eastern areas of Hull. It is heavily dominated by industry, HGV activity and businesses, with pockets of residential, retail, and educational buildings.
Slough Borough Council and their traffic signal consultants Atkins were looking for a more cost effective solution when upgrading multiple traffic signalised junctions along the very busy main A4 dual carriageway
Clearview Intelligence works on a wide variety of projects where ongoing maintenance is of huge importance to ensure continuous and accurate data collection. Good and reliable road network management is of paramount importance in our nation’s capital city where Clearview Intelligence equipment is key in ensuring smooth traffic flows.

Three major 1st class routes were identified for route safety solutions by our local partner in Slovakia.
The Shoreham Road forms a U-shaped link road providing access to air-freight warehousing associated with the Airport. In context, the top of the ‘U’ is in the north, the east and west outer sides are warehouses which are used to transfer freight between ‘airside’ (cargo planes) and ‘landside’ (HGVs).

Cambridgeshire County Council, in partnership with Milestone Infrastructure decided that all studs should be fully renewed.
With SolarLite Road Studs installed for the illumination of stretches on the M25 Motorway and also between the M2 and M20, Clearview Intelligence installed a quantity of 7,000 Road Studs between junctions 3, 4, 5 and 6 on the M40 Motorway providing ultrabright guidance to motorists around the clock.
