Today travel time by urban transport has varied as a result of developing urban facilities, land use pattern, development of transport infrastructure and alternative transport system options for communities. Different factors such as transportation mode, transportation distance, travel route as well as disability status, child ownership and working conditions play a role in the differentiation of individuals' travel time. However, age group, gender and the purposes of travel should be specified as some of the main factors among travel time differences that are investigated in this work in order to find out statatisticaly meaningful differences. This study has argued the differences between the travel times of urban transport throughout Ankara on these three basic factors. According to household survey in Ankara, it has been applied to Welch's ANOVA to research whether the participants' purposes of travel influence the average of travel time or not. It has showed that there are statistically considerable differences in general and gender between the average of travel time depending on the purpose of travel. It has been applied to post-hoc tests for determining purposes causing these differences. The difference has been generally seen between travel times for the purpose of work, school and shopping. Individuals from different age groups have differences in travel time for school and shopping. The purposes of travel and travel times of young and middle-age group distinguish from each other. However, there are no considerable differences for child age group between the purposes of travel and travel times by gender.
