Background and Aim: The trade-off between monetary wealth and fatal safety risks is explained by the value of statistical life, an efficient tool widely used to evaluate projects and allocate appropriate resources for road safety. The objective of this study was to estimate the statistical significance of life in order to improve road safety in the city of Ardabil, Iran. Materials and Methods:...

Several factors are considered in car accident analysis. Human factors research has shown that different perceptual and cognitive factors influence driving performance, leading to improvements in vehicle and road design. This case study provides a deeper understanding of the potential influence of major perceptual and cognitive variables on driving performance in general, including (a) driver e...

heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...

There are two main transportation engineering approaches to improving road safety: reactive and proactive. The traditional reactive approach consists of implementing the necessary improvements to existing hazardous (black-spot) sites in order to improve safety at these sites. The proactive approach is a collision prevention approach that tries to prevent unsafe road conditions from occurring in...
