Traffic flow is the estimated number of cars per hour passing through each road segment for a given time period. This estimate is the number of observed journeys scaled by a calibration factor. The calibration is calculated by comparing the observed flow to national AADF data, and can be refined further using any local contemporaneous  survey data (such as that produced by ATC surveys). Our sample of drivers should be homogeneously distributed throughout the country, as this best meets the needs of motor insurers. 

The thoroughfare blend is the ideal tool for gaining a street-by-street understanding of rat-running across a neighbourhood, town, or city.

We measure the number of times that cars travel along each road that did not start nor end within the study region. This measurement is part of what we call blend analysis – the proportions of traffic that originated or terminated outside or inside of a region of interest.  We supply four quantities as part of this analysis; the percentage of journeys travelling outside to inside, inside to outside, trips that are strictly internal to the region and those trips that travel through the region without the car parking.

At present, many thoroughfare studies involve feeding data from ATC surveys into a traffic model that then predicts the routes that vehicles take between survey locations.  In contrast, the thoroughfare blend solution looks at the actual route taken by the vehicles while inside a region. 

An estimation of the number of trips per hour between two locations.  The locations can be regions, such as town to town travel, or individual streets by creating virtual checkpoints.  Virtual checkpoints can be used to understand the car traffic travelling between the entry and exit roads to a region or neighbourhood, as well as the common routes that vehicles take as they pass through a network of such checkpoints.

We can provide speed statistics, such as the median or 85th speed, for every road segment in a region, per hour of the day.  Our speed data is particularly useful for providing a comparison between the current and historic behaviour through any UK road.

Sometimes customers want to know how journey times have changed between two epochs.  The Floow can provide a statistical measure of the travel time along user-defined routes. This analysis is useful for understanding how the travel time has changed across key junctions or road sections.

It is often desirable to understand how often vehicles make particular turns at major junctions.  We can offer an OD frequency analysis of all junctions with moderate to significant traffic within a study region or of specific intersections.
