The Challenge

Camera based civil traffic enforcement plays a central role in how local authorities manage road use. The challenge lies in applying complex rules accurately and consistently.

High Volumes, Multiple Schemes

Fixed bus lane cameras and vehicle detection cameras generate intentional traffic enforcement across bus lane and moving traffic contraventions.

Complex Statutory Requirements

Every traffic enforcement case must precisely satisfy statutory rules for signage, timings, exemptions, and vehicles before any PCN can proceed.

Consistency Under Scrutiny

Inconsistent civil traffic enforcement across TMA 2004 Part 6 schemes directly fuels appeals, delays outcomes, and escalates operational risk.

Automated Rule Application at the Point of Ingestion

The platform applies scheme specific validation rules as camera evidence is ingested from road safety cameras, vehicle detection cameras, and ANPR systems.

Operating times, permitted vehicle classes, exemptions, and signage conditions are checked automatically and not left to interpretation.

One Known Vehicle List. Every Scheme. No Gaps.

A centrally managed Known Vehicle List (KVL) ensures permits and exemptions are applied consistently across all enforcement schemes.

Updates are made once to the KVL and enforced everywhere, reducing risk, administrative effort, and inconsistent enforcement decisions.

A Structured, Standardised Review Environment

Officers review evidence within a purpose-built enforcement interface. Camera footage is shown alongside scheme rules, vehicle data, ANPR integration outputs, and exemption status.

This standardised workflow removes subjective variation and supports consistent decision making across all enforcement schemes.

A Complete, Transparent Audit Trail

Every review action is logged, including who assessed the evidence, what criteria were applied, and what decision was reached.

This audit trail carries through from capture to PCN issuance and appeal, enabling authorities to confidently manage feedback at the Traffic Penalty Tribunal.

Direct Integration with Back-Office Case Management

Validated cases move seamlessly from SiDem Traffic Manager into SiDem Case Manager, eliminating manual re-entry.

The full PCN lifecycle, including statutory correspondence, representations, appeals, and debt recovery, is managed within one integrated platform, preserving data integrity throughout.

How Our Products Support

Trellint’s traffic enforcement platform supports the full scope of camera-based enforcement operated by UK local authorities.

SiDem Traffic Manager

Trellint’s platform supports evidence used for bus lanes, moving traffic contraventions, school safety zones, low emission zones, zero emission zones, and congestion charging schemes. SiDem Traffic Manager ingests camera evidence, applies scheme specific validation rules, and provides a structured officer review environment.

Frequently asked questions

Traffic enforcement refers to the civil powers used by local authorities to manage road use and support road safety. In practice, this includes enforcing bus lane restrictions, moving traffic contraventions, school safety zones, low emission zones, and congestion charging schemes. These powers are exercised under statutory frameworks set out in the traffic management act, primarily the Traffic Management Act 2004 Part 6 (TMA 2004).

Fixed vehicle detection cameras located at defined enforcement sites capture video and image evidence of potential contraventions. Automatic Number Plate Recognition (ANPR) technology reads vehicle registration plates and, through ANPR integration, links vehicle data to validation and review workflows. Before a PCN can be issued, an authorised officer must confirm that the contravention occurred, that no exemption applies, and that all evidential requirements are satisfied. Clear, complete camera evidence is therefore essential.

Moving traffic enforcement covers contraventions that occur while a vehicle is in motion or has stopped where it should not, including banned turns, no-entry violations, box junction offences, and prohibited movements. These powers are granted under traffic management act 2004 part 6 and are enforced using camera evidence rather than Civil Enforcement Officers on street. Not all local authorities have these powers—they must apply for designation before operating moving traffic enforcement schemes.

A low emission zone (LEZ) or zero emission zone is a defined area where vehicles that do not meet specified emission standards are restricted or charged. Local authorities use camera systems to identify vehicles entering the zone and check them against emission and exemption data. Where non-compliance is confirmed, a PCN may be issued. Each scheme’s rules vary by authority and must be applied consistently to withstand challenge.

Traffic enforcement decisions are subject to challenge through formal representations and appeals, including referral to the independent Traffic Penalty Tribunal. Authorities must demonstrate that enforcement was carried out lawfully, consistently, and in line with TMA 2004 requirements. A complete audit trail is essential for defending decisions and maintaining public confidence.
