Transport for London

Traffic Management Act

The Traffic Management Act (TMA) 2004 places a Network Management Duty (NMD) on all traffic authorities.

This means they have to make sure road networks are managed effectively to minimise congestion and disruption to vehicles and pedestrians. It also requires roadworks to be planned and co-ordinated to consider the impact on neighbouring traffic authorities.

It is our responsibility under the Act to facilitate co-operation between all of London's traffic authorities and utilities so as to improve conditions for all road users. We have responded to this challenge with an array of actions and initiatives.

London Works

This business information system provides traffic planners and works promoters with details of all planned and current roadworks, and any other events which might disrupt traffic.

NMD Action Plan

This assesses our response to the NMD and our plans for the future. It helps the various businesses that make up TfL consider their NMD responsibilities when planning operations.

Traffic Management Learning Hub

This is a forum to share information, research, good practice and ideas. Through this forum Traffic Managers are provided with all the information, skills and tools needed to fulfil their NMD responsibilities.

London HAUC Expo

We organise this annual event for the London Highway Authorities and Utilities Committee. It provides a setting for partnership development and information sharing to help London collectively meet the challenges of the TMA. HAUC stands for Highway Authorities and Utilities Committee.
