TO WHAT EXTENT DOES URBAN DENSITY INFLUENCE THE MODAL SPLIT? THE LISBON METROPOLITAN AREA CASE STUDY

The relationship between urban density and car use appears to have a growing importance as urban areas experience sprawl and tend to be more diffuse. With this in mind, this paper examines a recent mobility survey conducted in the Lisbon Metropolitan Area (LMA). The main aim was to determine the extent to which density influences the modal split in identical situations of public transport supply and population demographics. Vehicle weight was considered the dependent variable, with 2 approaches developed: 1) one that considers the urban density, for each specific socioeconomic level, as the only explicative variable; and 2) one that uses a multivariate regression analysis using density, availability, family income, public transport supply, and public transit comfort levels as explicative variables of car use. Results obtained from both methods are compared and discussed in order to identify the real weight of density as an explicative variable of car use in LMA.
