Transport for London (TfL) is searching for a supplier to provide transport modelling software on behalf of the Greater London Authority.

TfL's Traffic Directorate (TD) has responsibility for delivering the mayor's Transport Strategy. As part of that the TD is responsible for over 1,000 km of London's busiest roads and the operation of 6,000 traffic signals.

The network is managed on a daily basis from the London Streets Traffic Control Centre to minimise the impact of both planned and unplanned events on traffic movements in the capital. TfL currently uses a variety of traffic modelling applications and tools which facilitate the efficient operation of the road network.

TfL says its contract requirement is for "software applications/tools that will allow traffic modelling at the area-wide, micro-simulation, network optimisation and signal priority junction levels".

TfL said it wishes to "engage with industry leaders and other experienced/innovative suppliers to develop and structure procurement requirements to best optimise market competition and deliver best value for the Authority".

TfL says it is looking for procurement interest from small-, medium- and large-sized companies in the contract, who will be able to bid either independently or through consortia groups.

All interested suppliers are being invited to attend an industry day event to be held on the 29 May in central London. The potential value of the contract has not been published.
