We are responsible for prosecuting people for offences committed under the New Roads and Street Works Act. We also operate a fixed penalty notice scheme. This document explains our policy. 

The documents below give advice and information to London Highway authorities and other stakeholders on the provision of winter services on London's streets and roads.

These documents have been considered by the London Winter Services Review Steering Group and the principles apply to all of London's streets.

Traffic modelling plays a vital role in smoothing traffic flow in London. Well designed and accurate models can help predict the effect of planned changes to the road network.

Our Traffic modelling guidelines and Model Auditing Process documents ensure consistency across the industry and enable best practice to be shared.

Traffic modelling guidelines

The guidelines are produced by our Traffic Directorate. All advice provided is non-binding but is directly related to the way we operate the Capital's traffic management systems.

Model Auditing Process (MAP)

MAP sets technical benchmarks for traffic modelling developed with or for us. It is used to improve the consistency of any modelling components forming part of a traffic scheme.

MAP should be used together with the modelling guidelines to inform scheme promoters, project managers and traffic model developers.

Pedestrian Countdown at traffic signals tells you how long you have to cross the road after the green man light has gone out.

In order to share knowledge built up during the extensive work to trial and prove the system, we produced a Technical Information Pack.

This pack is intended as a resource for other local authorities in England who are considering implementing Pedestrian Countdown.
