Nationwide Data Collection (NDC) regularly undertakes public transport surveys of every description. We have conducted numerous rail, bus and air passenger interview surveys at rail stations, bus stops/stations plus major airports throughout the UK & Ireland. In addition to passenger interview surveys we have also undertaken passenger flow counts and observation surveys to assist rail, bus and airport authorities in service planning and operational matters. The surveys often vary in scale from a single location to several hundred locations. The survey methodology employed includes manual, video and electronic data capture.
All NDC interview staff are fully briefed to ensure they are both familiar with the survey questions and the reasoning behind them. NDC staff would be of neat appearance and instructed to be polite at all times to members of the public. A comprehensive survey manual is always provided which clearly sets out the purpose of the survey and detailed instructions, including those relating to interpretation, for each question.
Inadequate supervision can lead to delays and problems at the data processing stages due to incomplete or inaccurate data. It is therefore standard policy within NDC that surveyors are overseen by experienced supervisors.
