Fast Vision-Based Road Tunnel Detection
When a vehicle equipped with an artificial vision system enters or exits a tunnel, the camera may temporarly suffer from reduced visibility, or even get completely blind due to quick changes in enviromental illumination. This paper presents a vision-based system that detects approaching tunnels entrances or exits. The proposed system allows other ADAS (Advanced Driver Assistance Systems) to act...
متن کاملOn-road and wind-tunnel measurement of motorcycle helmet noise.
The noise source mechanisms involved in motorcycling include various aerodynamic sources and engine noise. The problem of noise source identification requires extensive data acquisition of a type and level that have not previously been applied. Data acquisition on track and on road are problematic due to rider safety constraints and the portability of appropriate instrumentation. One way to add...
متن کاملAssessment of Simulator Fidelity and Validity in Simulator and On-the-road Studies
A lot of research groups all over the world have tried to relate results from driving simulator studies to real driving behavior. A solution, e. g. in form of a conversion table, would be of great value. Unfortunately, status quo is that even with expensive, high fidelity simulators the validity of results cannot be guaranteed. One reason for this is that a person’s behavior cannot be described...
متن کاملThe effect of road tunnel environment on car following behaviour.
In order to overcome urban space constraints, underground road systems are becoming popular options for cities. Existing literature suggests that accident rates in road tunnels are lower than those in open roads. However, there is a lack of understanding in how the road tunnel environment affects inter-vehicle interactions. In this study, car following data are obtained from traffic video foota...
متن کاملPerformance of High Velocity Electrostatic Precipitator for Road Tunnel
The particles emitted from diesel engine exhaust have low resistivity and extremely small in the range of 70-120nm. An electrostatic precipitator (ESP) has been extensively used for the collection of these particles. A two-stage ESP using charging section and collection section has been installed for the collection of diesel particles and improving the visibility index in road tunnels. The char...
