Distribution Functions’ Similarity of Population and Willingness to Old Car Scrapping (Case Study: Iran)

In the process of allocating budget for cars’ renewing programs, studying thewillingness of scrapping old cars is a parameter to estimate the number of new cars maybe purchased and the required budget should be allocated. To this purpose, the wellknownstatistical methods of Kolmogorov-Smirnov and Paired Two Sample for Meanshave been utilized to investigate the similarity of distribution functions and means ofproportions for population and willingness to old cars scrapping. Data, for populationand the number of scrapped decrepit cars in vehicle-recycling centers in Iran, has beencollected and analyzed. It has been categorized into ۳۱ provinces where the proportionof the population and the number of scrapped cars are respectively gathered based onthe national survey and the system outputs derived by transportation authorities. Theresults revealed there is no significant difference between the distribution functions ofpopulation size and the willingness of the old car scrapping. Therefore, the researchresults would support transport authorities for relying on population size to manage thevehicle-renewal programs as well as budget allocation.
