Logit Model Of Work Trip Mode Choice For Bole Sub- City Residents

The issue of mode choice is probably the single most important element in transport planningrnand policy making. It affects the general efficiency with which we can travel in urban areas,rnthe amount of urban space devoted to transport functions, and whether a range of choices isrnavailable to travelers (Juan De Dios Ortuzar, Luis G. Willumsen, 2004).rnThere are two transport studies undertaken for Addis Ababa which are part of therndevelopment and revision efforts of the Addis Ababa master plan. In both studies, the fourrnstage travel demand model was adopted. However, the mode choice models developed in bothrnstudies are direct demand models which are basically based on aggregate data.rnHowever, with present knowledge and computer technology, it is possible to model the modernchoice for more than two alternatives by considering both the travel maker’s and the travelrnmode’s characteristics. Moreover, considering both socio-economic and travel mode variablesrnwill lead to a better understanding and simulation of the people’s behavior in choosing amongrnthe competing modes. Therefore, in this research a Multinomial Logit model is developed,rnwhich is based on disaggregate socio economic, mode and trip related data, for work purposerntrips made by Bole Sub-City residents.rnThe different modes of road passenger transport considered in the model are Walking, SmallrnTaxis, Mini-Buses, Anbessa City Bus, Lonchina, Private vehicle as driver, Private vehicle asrnpassenger and Company provided transport.rnAmong the various methods of revealed preference surveys, Household or Home InterviewrnSurvey was used as a data source in addition to secondary data obtained from differentrnagencies of the city and this has been exploited to create the level of service data for therncompeting modes.rnFinally different specifications of multinomial Logit models have been tested and it has beenrnobserved that the mode choice model has shown continuous improvement as explanatoryrnpower as it was enhanced from being restricted to mode related variables to incorporating thernsocio economic and trip related variables.
