Abstract:

The objective of this study was to develop trip generation for residential areas, where Irbid city was selected as a case study. Household survey was carried out to collect data on trips and their purposes on typical workdays and holidays. Socio-economic characteristics of households were also obtained through field interviews. A total sample of about 2500 households was interviewed. 100 households were interviewed for validation purposes. Both regression analysis and cross-classification approach were used to model trip generation rates. Analysis carried out in the study indicated that the number of generated trips is influenced by family size, car ownership and income level. On workdays, the analysis indicated that the number of home-based work trips constitutes about one-third of the total home-based trips. Also, it was found that the number of trips on holidays represent nearly one-third of the number of trips generated on workdays. Although performance of both approaches was very well, cross-classification approach proved to yield more accurate values. Compared with developed countries, trip generation rates for residential areas in Jordan were found to be substantially low.
