Road Safety Management and Comparison of Low Cost and High Cost Plans And Selection of the Most Appropriate Plan

Abstract

This paper is aimed at controlling different access roads and activity-based gathering locations of Ahvaz-Andimeshk- Pol-e Zal axis, considering high cost and low cost engineering plans and finally selecting the best plan by comparing the above mentioned plans. Thus by estimating transportation request, analyzing low cost and high cost engineering plans including such factors as time, cost, quality, service life and durability, studying driving accidents and human and financial losses, and selecting the best plan, such results as improvement of transportation safety coefficient, low traffic to accelerate economic and social activities, public satisfaction, saving in fuel consumption through the shortest paths and finally protection of environment can be achieved with a view to provide sustainable road safety. Also comparison of early-return and late-return plans revealed that early-return plans, despite reducing accidents by 15 percent at the first stages, will not reduce accidents in long term. Late-return plans bring about more favorable results by studying roads thoroughly. This paper compares one of the examples of this area plans.
