Background and Purpose :Cost-benefit equations is one of the most important by of GNP and a training a Sustainable development as designated by professionals of occupational health .Therefore ‚ drivers as a forgotten index in sustainable development and its effect on community health.
Methods & Material : This descriptive analytical study involved the statistical community of 55000 vehicles in Sabzenar ‚Iran ‚from which 380 cases were splected by systematic sampling during six months from 17:00 to 20:00‚winter and spring 2011 with a traffic load peak ‚where right – trun violations were recorded at two major crossroads The obtained data were analyzed in SPSS 10.5 using normal Kolmogroff-smironoff and chi-square.
Results: significant relationship was observed between .occupation type and attitude (P=0.013) ‚ occupational history and attitude (P=0.03)‚ as well as residential area and attitude (P=0.011)‚ however‚ no significant relationship was found between age and attitude (P=0.0149)‚ education and attitude (P=0.0118) ‚ at a confidence interval of 95%. Total wasted time per year at a crossroad with three outlets was 1/123/260 hours per year. Given a 4 – cross road typical city in Iran with 340 cities ‚ an estimated 1/527/633/600 hours per year will be wasted. As far as the cost is concerned ‚ the total amount of gas wasted (7000 Rials/litre)will amount to 1/226/534/400 Rials per year in one single cross road in Sabzevar ‚Iran .The same equation applies here to produce a cost estimation of 167/280/000/000 Rials/year nationwide.
Conclusion: Immediate action for geometric correction of crossroads is required for preventing wastage of national resources and imposing economic costs on community members and the wasted time due to abnormal traffic behavior‚ increased GNP and moving toward Sustainable development will follow as a Consequence.
