Data from the 1971 Reading travel survey are used to determine the effect of location on the number of trips made by households. After classifying households according to their size and composition, car ownership, and location within one of three concentric sub-areas, the importance of each classification factor is tested statistically. Both household and person trip rates are considered for several combinations of trip purpose and mode of travel. The effect of linking trips through incidental purposes is also examined. The results show that household location generally had little effect on the trip rates. The two exceptions are cycle trips to school where the trip rate was lower in the central area; and walk trips to work where the trip rate was higher in the central area.
