Purpose. Test for a causal relalionship between neighborhood design and physical activity within the neighborhood by controlling for self-selection. Design. Cross-sectional and quasi-longitudinal analyses of residents of selected neighborhoods. Setting. Eight Northern California neighborhoods....

Transportation control measures are often implemented for their environmental benefits, but there is a need to quantify what benefits actually occur. Telecommuting has the potential to reduce the number of daily trips and miles traveled with personal vehicles and, consequently, the overall...

This paper defines the relationship between telecommunications and transportation, by expanding on linkages already identified in the literature, by identifying additional relationships, and by putting these relationships into a robust conceptual framework. There are conceptual, physical,...

On February 20, 1986, the regular monthly meeting of the Southern California Association of Governments (SCAG) Transportation and Communications Committee was held as a two-way videoconference. Analysis of travel changes associated with the videoconference showed that vehicle miles traveled...

It is a truism repeated countless times in the course of a transportation professional's career - "Travel is a derived demand" - that is, derived from the demand for spatially separated activities. Belief in this truism underlies a number of transportation policies designed to reduce motorized...

This paper examines the potential of telecommuting as a strategy for managing travel demand. In particular, the paper focuses on the travel and air quality implications of telecommuting. A study of travel impacts has been carried out using data obtained from the State of California Telecommuting...

The sprawling patterns of land development common to metropolitan areas of the US have been blamed for high levels of automobile travel, and thus for air quality problems. In response, smart growth programs— designed to counter sprawl—have gained popularity in the US. Studies show...

In this paper a conceptual model of the individual decision to telecommute is presented. Key elements of that decision, including constraints, facilitators, and drives, are defined and the relationships among them described. The major types of constraints (if negative) or facilitators (if...

This paper begins to operationalize a previously published conceptual model of the individual decision to telecommute. Using survey data from 628 employees of the City of San Diego, hypothesized drives to telecommute and constraints on/facilitators of telecommuting are measured. A binary logit...
