Beyond the journey to work

This paper analyses the Nationwide Personal Transportation Study (NPTS) surveys of 1977 and 1983-1984 that reveal a remarkable increase in nonwork travel. This growth occurred among all city size classes but was stronger for suburban residents. Also interesting is that the rate of increase in nonwork trips was higher in the peaks (especially in the morning peak) than in the off-peak period. Some, but not all, of these trips may be price-elastic and might be diverted by congestion pricing strategies. The nonwork trip growth is concentrated in the ‘family and personal’ and the ‘social and recreational’ categories. Although higher-income households make more trips than low-income households, the increase in nonwork travel is common to all income groups. The growth in nonwork travel does not appear to be closely associated with the growth in female employment or trips related to the children of working women. The most convincing explanation of the growth in nonwork travel is that the trip cost savings (less time and distance) experienced because of more efficient spatial settlement patterns have provided an incentive to undettake more trips. Another implication is that urban economic models and urban transport policies have overemphasized the journey to work, especially to the central business district (CBD).
