Based on 2001-census data for Belgium, energy consumption levels for commuting were calculated and mapped on the basis of residential locations in the administrative regions of Flanders and Brussels. Comparison with regional differentiations in commuting distances, modal shares of non-car travel modes and aspects of infrastructure and population densities clarifies some relationships between energy consumption, commuting behaviour and spatial-economic structure in the suburbanised historic–polycentric spatial structure which characterises the northern part of Belgium. It is found that mode choice appears to be of little impact for the energy performance of home-to-work travel on the scale of the Flanders region. At the other hand, proximity between home and work locations is paramount.Residential density plays a part in this, although much depends on the specific situation. This is also the case for the accessibility of the main road and rail network. In some regions these infrastructures induce long-distance commuting, whereas in the economic core areas this effect is much less pronounced. All these are factors that are very much determined by infrastructural and spatial policies of the past. 相似文献

A reasonable response to increasing traffic congestion may come from the rapidly developing traveler information systems. Such systems may be successful if they effectively influence drivers' enroute decisions; in this regard, a critical factor may be commuters' willingness to divert from their regular route in response to information about traffic congestion. This study evaluates the effects of real-time traffic information along with driver attributes, roadway characteristics and situational factors on drivers' willingness to divert.The empirical portion of this study is based on a survey of downtown Chicago automobile commuters. The stated preference approach was used to study commuters' diversion propensity. Drivers expressed a higher willingness to divert if expected delays on their usual route increased, if the congestion was incident-induced as opposed to recurring, if delay information was received from radio traffic reports compared with observing congestion, and if trip direction was home-to-work rather than work-to-home. Respondents were less willing to divert if their alternate route was unfamiliar, unsafe or had several traffic stops. Socioeconomic characteristics were also significant in predicting willingness to divert. 相似文献

Studies that model the effects of land use on commuting generally use a trip-based approach or a more aggregated individual-based
approach: i.e. commuting is conceptualized in terms of modal choice, distance and time per single trip, or in terms of daily
commuting distance or time. However, people try to schedule activities in a daily pattern and, thus, consider tours instead
of trips. Data from the 2000 to 2001 Travel Behaviour Survey in Ghent (Belgium) illustrate that car use and commuting times
significantly differ between commuting trips within work-only tours and more complex tours. Therefore, this paper considers
trip-related decisions simultaneously with tour-related decisions. A multiple group structural equation model (SEM) confirmed
that the relationship between land use and commuting differs between work-only tours and more complex tours. Trips should
be considered within tours in order to correctly understand the effect of land use scenarios such as densifying on commuting.
Moreover, the use of multiple group SEM enabled us to address the issue of the complex nature of commuting. Due to interactions
between various explanatory variables, land use patterns do not always have the presumed effect on commuting. Land use policy
can successfully influence commuting, but only if it simultaneously accounts for the effects on car availability, car use,
commuting distance and commuting time. 相似文献

Since the passage of the Intermodal Surface Transportation Efficiency Act in 1991, a significant number of state highway agencies have started to develop and implement statewide travel demand models to meet policy and legislative development needs. Currently, however, a lack of up-to-date multimodal and inter-regional passenger travel data hampers analysts’ ability to conduct quantitative assessments of long-distance travel infrastructure investment needs, at both the national and statewide levels. Despite these data limitations, but also largely shaped by them, long-distance travel modelling has become an increasingly popular topic in recent years. This paper reviews several methodologies for multimodal inter-regional travel demand estimation, drawing examples from both state-specific modelling within the USA and from fully national models being developed and applied in other parts of the world, notably in Europe. 相似文献

This paper develops a structural and empirical model of subsistence activity behavior and income. Subsistence activity decisions (work participation and hours of work decisions) and income have an important bearing on activity and travel behavior of individuals. The proposed structural model represents an effort to analyze subsistence activity behavior and income earnings to support a better understanding, and reliable forecasting, of individual travel behavior. The empirical model formulates and estimates an integrated model of employment, hours of work and income which takes account of interdependencies among these choices and their structural relationships with other relevant variables. Social factors that inhibit an individual's employment and work hours decision and affect an individual's income are incorporated in the model. A sample of households from the Dutch National Mobility Panel is used in the empirical analysis. 相似文献
