Road Safety Behaviour
Road user behaviour is one of Trafitec's core competences
We have extensive experience in recording, assessing and questioning the behaviour and experiences of road users, as well as their understanding of the design and marking of traffic areas. We perform tasks such as:
- Video-based behavioral studies
- Recording traffic conditions in the field
- Surveys
- Eye track - visual behavior
- Traffic counts
- Speed and position of road users on the road
- Interaction behaviour, inappropriate behaviour, conflict behaviour, etc.
- Road user satisfaction surveys
- Road users' understanding of road signs and other markings
- Perceived satisfaction, safety and level of service
- Capacity assessment
Behavioral studies are often conducted on site or based on video recordings. We carry out and use recordings from surveillance cameras and cameras attached to drones, lifts, vehicles, roadside equipment, stands, etc. Recordings are automatically analyzed by software, by Trafitec employees or by subcontractors.
Based on systematic behaviour recordings, we develop eg. models to describe the capacity of roads, paths and intersections. We also use counting equipment and speed measurements. We investigate the speed choices of road users and test measures to adjust speed.
We are trained conflict technique observers. By recording traffic conditions on site, we assess poor interaction behaviour and "near misses", where road users are on a collision course and avoid each other only at the last moment. Our basic knowledge of the traffic performance of road user groups enables us to carry out highly qualified on-site traffic inspections and/or to assess road user behaviour from video.
Trafitec conducts surveys. We are experienced in designing questionnaires and interview frameworks. We investigate, among other things, road users' understanding and use of traffic signs as well as safety, experience and attitudes.
We use eye tracking to record road users' visual behaviour. Trafitec is experienced in evaluating eye tracking, including distraction, inattention and visibility of traffic signs and markings. Since we use mobile eye track glasses we are able to record and assess the visual behaviour of among others pedestrians, cyclists and drivers.
