Abstract

The role of the street environment in the way people cross roads in urban settings is modeled. Respondents were placed in real traffic conditions at the curbside of street blocks in the Tampa Bay, Florida, area for 3-min observations of the street ...

Abstract

Monitoring the movement of pedestrians in everyday environments is difficult, especially if accurate data are required. Typically, data pertaining to the origins and destinations of pedestrians as they move around a space can be obtained only by either ...

Abstract

In 2002 the city of Oakland, California, implemented a scramble signal at the intersection of 8th and Webster Streets. Scrambles are traffic signals that give pedestrians exclusive access to an intersection by stopping vehicular traffic on all approaches, ...

Abstract

Phase 2 of New Jersey's bicycle and pedestrian master plan is an innovative approach to quantify bicycle and pedestrian needs at the statewide level. In cooperation with New Jersey's three metropolitan planning organizations (MPOs), the New Jersey ...

Abstract

Pedestrian countdown signals installed at five intersections in Montgomery County, Maryland, were evaluated with a before-and-after study. The effect of the countdown signals on pedestrian and motorist behavior was determined by observing the signal ...

Abstract

The Department of Transportation of the city of Charlotte, North Carolina, has developed a methodology to assess the important design features that affect pedestrians and bicyclists crossing signalized intersections. Referred to as level of service, this ...

Abstract

Pedestrians who are blind or visually impaired often travel in areas that are unfamiliar to them and cross at signalized intersections. Results are reported of testing street crossing by blind pedestrians at complex, unfamiliar signalized intersections ...

Abstract

The pedestrian crossing process in roundabout areas is modeled as a two-stage crossing demarked by a splitter island. A composite queuing system is used to describe the process. The system was simulated by using Arena, a general-purpose simulator chosen ...

Abstract

An innovative pedestrian modeling technique known as Space Syntax is described. The technique was used to create estimates of pedestrian volumes for the city of Oakland, California. Pedestrian exposure rates were calculated, and a relative risk index for ...

Abstract

A pedestrian and traffic safety study was conducted in San Diego County, California, with 1,587 adult and teenage traffic violators who were attending traffic school. The surveys were disaggregated on the basis of respondents' demographic characteristics. ...

Abstract

The assessment of station designs by applying pedestrian flow simulation models is addressed. In particular, station design issues pertain to the way access gates will affect pedestrian flow operations in regard to levels of service, congestion levels, ...

Abstract

Assessment tools for pedestrian walking speeds, comfort, and travel times are important for the planning and geometric design of infrastructural facilities under regular and safety-critical circumstances (evacuations). This contribution focuses on ...

Abstract

In response to renewed appreciation of the benefits of bicycling to the environment and public health, public officials across the nation are working to establish bicycle routes. During the past two decades a number of methods have been endorsed for the ...

Abstract

During the past 10 years the U.S. Department of Transportation has spent $3.9 billion on bicycle and pedestrian facilities through the Transportation Enhancements Program. These funds have been distributed to 11,456 projects. Of these funds $2.53 billion ...

Abstract

An ordered-response model is used in this research to evaluate the factors that affect frequency of bicycle use for a person's commute to and from work. Data used were gathered during an original survey effort conducted over the Internet in 2002. ...

Abstract

In recent years the number of kick scooters, hand cycles, wheelchairs, and other emerging user types has increased on roads and shared use trails. FHWA recognized that because AASHTO's design recommendations are based on the characteristics of bicyclists, ...

Abstract

Various techniques are available for monitoring, improving, and assessing safety needs on the total road network. These techniques generally include procedures that look subjectively at the standards of road safety being achieved and maintained by road-...

Abstract

The recent enactment of the transportation barrier-free law in Japan emphasizes the importance of incorporating a barrier-free approach for any new road facility construction and for improvements to existing road facilities in urban areas. The purpose of ...

Abstract

In developing countries, air quality assessments that include the transportation sector have tended to focus predominantly on assessing technological solutions to problems associated with vehicle pollutant emissions, energy consumption, and greenhouse ...

Abstract

With the rapid advancement of intelligent transportation systems technologies in recent years, an unprecedented opportunity exists for developing countries to develop their transportation system and supporting infrastructure by taking full advantage of ...
