Benchmarking Trafsense® AID @ 20 000 vehicles a day

The project is partially funded by Innovation Norway under the Pilot-T innovation program intended to accelerate the development of future transport systems with superior safety and efficiency, and reduced emissions.

Automatic Incident detection (AID) is implemented for three incident types:

• Stopped vehicle
• Wrong-way driving
• Queue
  
  

The test site is the 1 115 m westbound bore of the Lyderhorn tunnel on RV555 west of Bergen (Norway). Its dual lanes serve an AADT of 20 000.

The pilot installation of the Trafsense^® system was established Q1 2023. The testing and evaluation will be finalized throughout Q4 2024.

The Norwegian Public Road Administration’s (NPRA) selection of test site was based on two features:

• The high AADT coupled with significant congestion issues during rush hours.
• The availability of an existing camera-based AID-system providing both performance benchmarking and thorough verification through incident-triggered videos.
  
  

The video below shows real-time Trafsense^® traffic data from the test site:

Video visualization of real-time Trafsense® traffic data from the 1 115 m dual lane westbound bore of the Lyderhorn tunnel on RV555 west of Bergen (Norway), AADT 20 000 for this bore. The number inside each vehicle icon is the speed in km/h. Note that the tunnel bore is split into two halves in the video to fit the limited screen width.
