New SEA camera system aims to improve safety at schools

Cohort company SEA has successfully delivered 20 traffic camera detection systems to help improve child safety outside schools in the Borough of Bedford.

SEA’s ROADflow technology is already employed by 51 local authorities across England to monitor road traffic offences ranging from yellow box infringements to unauthorised manoeuvres.

In addition to Bedford, SEA’s ROADflow technology is being utilised in Newcastle to detect offences where vehicles encroach into bus lanes and areas reserved for buses outside schools, and other systems addressing bus stop infringements have now been commissioned in Derby and Plymouth.

The ROADflow cameras capture details of vehicles that stop in a specific area and for longer than defined location permits. These cameras are fully automated, re-deployable and can use existing road lighting columns, which allows enforcement to take place where previously it could be impractical. The technology also allows two lanes to be monitored with a single camera. Encrypted communications use the mobile network to transmit data to the back office for enforcement processing. 

To ensure maximum effectiveness, SEA performs detailed modelling of each camera location before installation using camera siting software developed in-house. This allows a full survey of any new site to be performed at the desktop, assessing which offences can be detected and allowing the optimal camera locations to be determined.

Steve Hill, SEA Managing Director, commented: “Research from insurance companies suggests that over 1,000 children a month are involved in collisions within 500metres of school gates. ROADflow technology is proving a valuable resource in improving road safety near schools, for example providing a deterrent to vehicles dropping off or picking up passengers in non-designated areas or bus stops outside school gates.”

The system’s effectiveness is further increased by extensive remote health monitoring of all camera outstations, and functionality tests regularly check the performance of each system. If an issue is detected, an alert will be sent immediately to a SEA engineer, who will be able to resolve the issue, often before the local authority is aware.

SEA ENHANCES ROADFLOW CAMERA NETWORK IN CARDIFF

Cohort company and road technology specialists SEA have expanded the traffic enforcement footprint of Cardiff Council by installing a further ten road traffic camera systems to enforce yellow box-junctions and unlawful manoeuvres.

The latest ROADflow installations will enhance the 30 SEA Flexi and Motion roadside cameras already in operation in the Welsh capital as it seeks to reduce the congestion impact of traffic growth.

In line with Cardiff’s transport strategy, SEA’s cameras support the Moving Traffic Offences scheme to help persuade more commuters to switch from cars to buses. SEA is proud to support Cardiff in realising its ambition to become Europe’s most liveable capital city.

SEA’s ROADflow Motion provides sophisticated monitoring and enforcement, as it tracks vehicles continuously through junctions. The cameras use a 3D ANPR in-house rules engine software component which categorises vehicle movements and allows detection of specific behaviours. The engine was developed to tolerate losing sight of vehicles for short times, which often occurs during heavy congestion.

ROADflow Motion provides all weather capability that allows very high detection rates and low false alarm rates to be achieved in all weathers and lighting conditions.

The system builds a 3D view of the road using data from infra-red illuminating cameras which maximise the number of offences captured whilst minimising review effort associated with non-incidents. This avoids relying on video analytics which can be unreliable in poor weather and at night.

The simple modularity of the ROADflow technology, which enables cameras to be added easily to the system using its plug and play capability, means that Cardiff has been able to expand its network over a period of time, taking into account budget considerations.

Steve Hill, SEA Managing Director, adds: “Our five year agreement with Cardiff Council provides the possibility of incremental expansion of the camera network in the City in the continuing effort to improve driver behaviour and reduce congestion. The statistics demonstrate the effectiveness of the technology which is enhanced by a full support package that provides improved reliability and asset availability.”
