COUPLING MODELS OF ROAD TUNNEL TRAFFIC, VENTILATION AND EVACUATION

Traffic Flow Models and the Evacuation Problem

In our paper, we consider several models for traffic flow. The first, a steady state model, employs a model for car following distance to derive the a traffic flow rate in terms of empirically estimated driving parameters. From this result, we go on to derive a formula for total evacuation time as a function of the number of cars to be evacuated. The steady state model is analytically convenien...

Study on Applicability of FDS+Evac for Evacuation Modeling in Case of Road Tunnel Fire

In this study, fire in a short 2-lane single-directional road tunnel with two different traffic situations is considered and the impact of spread of fire and smoke on people evacuation is investigated. The FDS+Evac system used comprises of FDS (Fire Dynamics Simulator), an advanced CFD (Computational Fluid Dynamics) fire field model supplemented by agent-based FDS evacuation model, Evac. Evac i...

Comparison of the MOVES2010a, MOBILE6.2, and EMFAC2007 mobile source emission models with on-road traffic tunnel and remote sensing measurements.

UNLABELLED The Desert Research Institute conducted an on-road mobile source emission study at a traffic tunnel in Van Nuys, California, in August 2010 to measure fleet-averaged, fuel-based emission factors. The study also included remote sensing device (RSD) measurements by the University of Denver of 13,000 vehicles near the tunnel. The tunnel and RSD fleet-averaged emission factors were compa...

Association of Road Traffic Noise Exposure and Driving Behaviors

Background: The noise caused by traffic is an increasingly prominent feature of urban environments. However, limited studies have been focused on the assessment of exposure-response relationship between road traffic noise exposure and driving behaviors in Iran. The present study aimed to investigate the prevalence of the violations caused by road traffic noise exposure in Qazvin, Iran. Methods...
