From travel surveys, the general public's traveling characteristics are obtained. The traveling characteristics of people allow transportation planners, through computer modeling, to predict the traffic on street networks. One problem with travel surveys is missing trips. Travel surveys do not account for all trips. This thesis presents the results of a study comparing household travel surveys with workplace travel surveys. The objective for the study was to find where trips are missed in household and workplace travel surveys. By finding the differences between the trip rates of the two surveys, missing trips were found. Trips are missed because people do not remember all of their trips. This thesis tries to account for the missing trips by comparing the trip rates of workers found in the two different surveys, household and workplace. Trip rates were found for all trip types-home based work (HBW), home based non-work (HBNW), and non-home based (NHB) trips. The thesis concluded that people remember more non-work trips associated with the place or location of the survey. If a person is at work, he will remember more non-work trips associated with work. If at home, a person will remember more non-work trips associated with the home
