Surrogate Safety Measures from Traffic Simulation Models

Surrogate Measures of Safety

Economic Evaluation of Road Traffic Safety Measures

The economic appraisal of road safety measures poses the basic problem of determining which method to use for the valuation of road safety measures. Given that road safety or, to be more precise, lack of road safety is measured in terms of the total number of fatalities and injuries, either slight or severe, the economic calculation can be based on the value of human life and the estimated cost...

Learning surrogate models for simulation-based optimization

We address a central problem in modeling, namely that of learning an algebraic model from data obtained from simulations or experiments. We propose a methodology that uses a small number of simulations or experiments to learn models that are as accurate and as simple as possible. The approach begins by building a low-complexity surrogate model. The model is built using a best subset technique t...

Synopsis of Traffic Simulation Models

Computer simulation modeling is an established tool for assessing traffic operations. Over the past three decades, a variety of traffic simulation models have been developed, and many experiments and applications of these traffic simulation models to imaginary and real traffic operations have been conducted. This paper is intended to review widely used and newly developed models, in terms of mo...

Simulation Models of Traffic Flow

This paper reviews the range of traffic models, with particular attention to microsimulation. Although there are major types, there are so many hybrids that it is difficult to classify them all. The standard way of assigning traffic to a network is to find a static equilibrium from which no driver would be able to find a quicker route. This gives fairly good predictions of the link flows result...
