Traffic Modelling Data

We have a dedicated team who specialise in data for traffic modelling. This includes Degree of Saturation (DOS) / Underutilised Green Time (UGT) surveys and saturation flows. As these types of surveys can be subjective, we record high/low demand readings on video to ensure a permanent record that can be referred back to (see below for example). The data is used for modelling in programs such as LINSIG, TRANSYT and VISSIM.
