| Abstract | The aim of this research is to analyze and evaluate the road traffic accidents costs in Sudan by determining the total economic loss from road traffic accidents relative to the Gross Domestic Product (GDP). Moreover, the value of statistical life (VOSL) of Sudan Pedestrians that can be used efficiently in the cost –benefits analysis aspect is estimated. In Sudan, as in many other developing countries, the economic loss of traffic accidents is noticeable; however, analytical research to estimate the magnitude and impact of that loss is lacking Two analysis approaches were used to fulfill the study objectives. The Human Capital (HC) method is appliedfor estimating the overall road traffic accidents costs and the unit cost of each crash severity levels. While, the Willingness –to –pay (WTP) withContingent Valuation(CV) method is used for determining the pedestrian's value of statistical life (PVOSL). Moreover, this study examines the impact of pedestrians’ Socio –economic characteristics, risk level and walking behavior factors on their WTP forafatalityrisk reduction in Sudan.The research findings indicate that, the total cost of road traffic accidents in Sudan in 2010 was estimatedat US$391 million, which represents 0.57% of the GDP. Meanwhile, in 2011 the cost was calculated to reach US$413 million, representing 0.62% of the GDP. Unit costs for each crash severity level, death, disability, serious injury, slight injury, and vehicle damage were also estimated in two years, 2010 and 2011. The accident cost for death or fatality was equal to US$38,932 and 39,508 in 2010 and 2011 respectively. The accident cost for disability was equal to US$43,113 and US$45,165; serious injury was equal to US$6,963 and US$7,596; slight injury was equal to US$2,570 and US$3,198 and vehicle damage only was equal to US$2,268 and US$2,579 in the assessment years of 2010 and 2011, respectively.On the other hand, the WTP-CV approach was used to determine the amount of money that pedestrians in Sudan are willing to pay to reduce the risk of their death. The impact of the socioeconomic factors, risk levels, and walking behaviors of pedestrians on their WTP for fatality risk reduction was also evaluated. Data were collectedfrom two cities—Khartoum and Nyala—using a survey questionnaire that included 1,400 respondents. The WTP-CV Payment Card Questionnaire was designed to ensure that Sudan pedestrians can easily determine the amount of money that would be required to reduce the fatality risk by a pedestrian-related accident. The analysis results show that the estimated VOSL for Sudanese pedestrians ranges from US$0.019 to US$0.101 million. In addition, the willingness-to-pay by Sudanese pedestrians to reduce their fatality risk tends to increase with age, household income,educational level, safety perception, and average time spent on social activities with family and community. |
