Drones for Advanced Traffic Analysis

A single drone and operator can safely cover a whole traffic island or transport corridor. Operating the drone from a safe location, away from traffic, the drone can record high resolution video, getting a perspective not normally possible.

Problem

Traditionally, a traffic survey would involve a team of traffic surveyors, manning each exit of a traffic island or intersection, manually counting traffic over a given period.

For a typical island this may require 4 personnel who may also need to be swapped out for breaks.

This is labour intensive, putting staff in vulnerable positions and will only provide a limited data set, such as traffic count.

Situation

Traffic surveys are employed for a number of reasons usually related to planning applications or traffic behaviour modelling.

Statistics such as traffic flow count, origin / destination matrix and queue wait times are required.

Solution

A single drone and operator can safely cover a whole traffic island or transport corridor. Operating the drone from a safe location, away from traffic, the drone can record high resolution video, getting a perspective not normally possible.

This perspective enabled us to capture video footage of traffic behaviour which can then be analysed and detailed data extracted.

How can drones help with traffic analysis?

One drone & operator is enough to cover the whole intersection or even a whole transport corridor.

With the elevated view afforded by the drone, you can get extremely accurate traffic data such as counting of object in classes, origin / destination matrix but also other possibilities such as speed acceleration and object size.

Using AI technology we are able to extract valuable data, quickly and accurately from our aerial footage.


With this accurate telemetric data, it is possible to detect dangerous situations, calibrate models of driver behaviour or even count the capacity of crossroads and much more.

This then enables traffic behaviour to be analysed, all from the same set of footage.

Accurate Data

The following are some of the possible metrics extracted from traffic footage:

The major benefit here is that once a survey is concluded and you wish to expand on that survey, the data does not need to be collected again. We will simply process the original dataset to extract the new metrics required.

Using drones and AI for traffic analysis can bring several benefits to a traffic survey project, especially where detailed data is required.

Time, cost and risk initially spring to mind, but the level and accuracy of data available is real game changer.

We're excited to be offering these innovative services to our clients and proving the benefits that they can bring to projects taking advantage of them!

We are keen to discuss this workflow with traffic analysis companies, local authorities and highways agencies to show the benefits an aerial survey can bring to a project.
