Answer for Traffic Surveys

Answered By: 
The Mayor

Understanding traffic movements and volumes by all modes is central to planning transport strategies, improvement schemes etc and survey data must be gathered to assist highway authorities, whether TfL, or local boroughs, to make informed decisions. Surveys are undertaken for a variety of reasons:· London-wide for strategic and performance monitoring· monitoring traffic in the central London Congestion Charging zone · for the London Area Transport Survey (LATS), which collects statistical data on the origins and destinations of cars and commercial vehicles for purposes of strategic transport modelling. LATS is used to provide base data for central Government, local Government and TfL· to monitor specific scheme and corridor development and managementTfL undertakes traffic surveys using a small, in-house Traffic Survey Team, supplemented by specialist consultants when required. Surveys can be in a variety of forms including traffic volume and classified (by vehicular type) counts, turning counts, speed surveys, queuing surveys, pedestrian counts or cycle counts. It is only roadside interview surveys that actually require that traffic is stopped to ask questions of the driver because of the nature of the data collected.A breakdown of traffic surveys in the format requested is not readily available, and it would be extremely time-consuming for TfL to provide this. If you are interested in surveys undertaken in a particular location please contact TfL.
