The research question addressed in this paper is whether or not occupant death, injury, and ejection outcomes differ between vehicles equipped with 3-point manual belts versus 2-point motorized-shoulder/manual-lap (motorized/manual) belt systems. Census crash data sets for the states of Washington and Texas, and the Fatal Accident Reporting System (FARS) were subset to provide data on front-out...

Existing regional travel forecasting systems are not typically set up to forecast usage of bicycle infrastructure and are insensitive to bicyclists' route preferences in general. We collected revealed preference, GPS data on 162 bicyclists over the course of several days and coded the resulting trips to a highly detailed bicycle network model. We then use these data to estimate bicyclist route ...

An intra-urban hierarchy of activity centers interconnected by non-motorized and public transportation is broadly believed to be the ideal urban spatial structure for sustainable cities. However, the proper hinterland area for centers at each level lacks empirical study. Based on the concentric structure of everyday travel distances, working centers, shopping centers, and neighborhood centers a...

The decision whether to obtain a driving license has a substantial effect on a person’s travel behaviour for the rest of his/ her life and on lifetime CO2 emissions. In heavily motorized societies, non-drivers often decide to obtain a driving license simply because others one, and with little unawareness of the negative aspects of automobile use. It is hypothesized that providing non-drivers wi...

Commuters rely on realistic and real-time information in order to optimize the time spent on commuting between home and work. Delays in (urban) transport and congestion for individual motorized transport are a major issue for unnecessary long travel times. While some of these delays occur randomly, there is also a systematic component. In this paper we describe a data-driven approach to analyze...

This study reviews the impact of roadside friction on urban arterial roads in published literature and aims to identify various side frictional parameters that roads. The are non-motorized vehicles, pedestrian crossing or moving along road, street vendors, on-street parking, animal movement, land-use activity. all these traffic performance leads a reduction capacity, speed (instantaneous speed,...

The 2-degree guardrail of global warming, together with accelerating urbanization and growing scarcity of oil, demands a redesign of todays’ sprawling cities in order to limit greenhouse gases and bring about efficiently built-up structures. In 2001, 42 percent of commuter paths within Vienna are traveled by private cars. This week-daily, recurring traffic pattern causes tons of Co2 and support...

BACKGROUND Previous systematic reviews indicate that active transportation (AT; the use of non-motorized travel modes such as walking, running and cycling) is an important source of daily physical activity (PA). However, no previous systematic review has examined travel behaviours among African children and youth or the psychometric properties of measurement tools used among children and youth ...

This report critically evaluates transport policy and project evaluation practices, and describes ways to make them more comprehensive and multi-modal. The conventional transport planning paradigm is mobility-based, it assumes that the planning objective is to maximize travel speed and distance, and evaluates transport system performance based primarily on automobile travel conditions. A new pa...
