Trip frequencies in subareas
Trip frequency analysis was based on data from the daily travel investigation. In particular, close interdependence of activity participation could be expected. However, because of the possibility of combining several activities, such as shopping at different locations, and thus making several journeys in connection with the same activity, on average, the travel daily respondents made three journeys per day during the investigated weekdays and during the weekend. The total number of journeys appears to be influenced by the urban structure. The effect of local area density on the number of journeys at the weekend is more difficult to explain, but it might reflect a tendency found among residents of dense, inner city areas to reduce the number of shopping and visiting trips carried out at the weekend. However, some theorists have assumed that “distance decay” will, by and large, also have an effect on the number of days per week that the workplace is visited, since information technology and improved communication have made it possible for an increasing number of employees to do some of their work from home. Location of the residence in hierarchy relation centers in the metropolitan area has some influence on the frequency of participation in different activities. Visits to typical “urban” facilities like cinemas and restaurants are more common among inner city dwellers, while residents of outer suburbs go to other provinces more frequently, and spend more time on recreation (see Table 7).
