In many developing countries, transportation infrastructure development lags behind the tremendous growth in motorization. Road traffic injuries cause enormous morbidity and mortality worldwide, placing heavy burdens on global and national economies. .Underdeveloped transportation infrastructures critical to traffic safety include roadway improvement, occupant protection laws, traffic law enforcement, and emergency medical services (EMS). Highlighting one important aspect of lagging infrastructure, this article focuses on emergency medical services. This research study offers a descriptive...

Cooperative Adaptive Cruise Control: Testing Drivers’ Choices of Following Distances

A Cooperative Adaptive Cruise Control (CACC) system has been developed by adding a wireless vehicle-vehicle communication system and new control logic to an existing commercially available adaptive cruise control (ACC) system. The CACC is intended to enhance the vehicle-following capabilities of ACC so that drivers will be comfortable using it at shorter vehicle-following gaps than ACC. This can offer a significant opportunity to increase traffic flow density and efficiency without compromising safety or expanding roadway infrastructure.This report describes the design and implementation...

Authorized Vehicles Only: Police, Parking, and Pedestrian Access in New York City

Moran, Marcel E
2023

Sidewalks and crosswalks serve little purpose for pedestrians if they are routinely obstructed by automobiles. In New York City, local journalists and transportation advocates have drawn attention to this occurring, particularly in certain settings. Specifically, there is consistent photographic evidence that streets surrounding New York Police Department (hereafter, NYPD) offices are replete with cars parked on the sidewalk and within crosswalks. Though clearly problematic for pedestrians and abutting residents and local businesses, this type of parking behavior has not been studied...

A Specification Of An Automated Freeway With Vehicle-Borne Intelligence

Hitchcock, Anthony
1992

The focus of this work is to derive a technique of safety analysis for an automated freeway system. To demonstrate the method of safety analysis a procedure called fault tree analysis is applied. The specified freeway operates with vehicles in platoons. The safety criterion used here is that two or more simultaneous faults must occur independently before the hazards can arise.

A Machine Vision Based System for Guiding Lane-Change Maneuvers

Malik, Jitendra
Koller, Dieter
Luong, Tuan
1995

We propose a new approach for vision based longitudinal and lateral ve-hicle control which makes extensive use of binocular stereopsis. Longitudi-nal control - i.e. maintaining a safe, constant distance from the vehicle infront - is supported by detecting and measuring the distances to leadingvehicles using binocular stereo.A known camera geometry with respect tothe locally planar road is used to map the images of the road plane in thetwo camera views into alignment.Any significant residual image disparitythen indicates an object not lying in the road plane and hence a potentialobstacle....

The Influence of Self-Efficacy and Perceived Safety in Neighborhood on Children’s Frequency of Walking to/from School

Walking is among the common transportation methods utilized by children to commute between home and school. Previous research indicates children’s intrapsychic characteristics such as self-efficacy play an important role in their decision to walk to/from school. Few studies have addressed the role of parent self-efficacy in these decisions. Furthermore, environmental factors such as neighborhood safety have mixed effects on children’s decision to walk to/from school

Methods Of Analysis Of IVHS Safety: Executive Summary

Hitchcock, Anthony
1992

This report presents the executive summary to a study on developing and demonstrating methods by which the safety of Intelligent Vehicle Highway Systems (IVHS) can be assured, assessed and evaluated. Safety considerations were studied for automated freeways, driver aids and copilots. Management and policy issues are briefly discussed in conclusion.

Giving Cycling the Green Light: An Overview of Transportation in Ireland and the Design of the National Cycle Network

Manton, Richard
2013

Similarly to the US, driving a car to work continues to gain ground in Ireland and the country is presented with major challenges in environment and health as a consequence. In safety, at least, Ireland has had some major successes. In 40 years, the number of fatalities has fallen from 640 to 162, a drop of 75%. Such improvements in road safety have been attributed to a combination of education, enforcement and engineering. Pedestrian and cyclist fatalities have each fallen by 66% in 20 years, however, this could be attributed to the lower numbers of people walking and cycling....

Gap Acceptance for Vehicles Turning Left Across On-Coming Traffic: Implications for Intersection Decision Support Design

Ragland, David R.

2005

A left-turning vehicle (Subject Vehicle, SV) attempting to cross the path of an oncoming vehicle (Principal Other Vehicle, POV) at an intersection typically does not have the right of way. The main task of the SV driver is to find an adequate opportunity in opposing traffic to initiate the left-turn maneuver. To reduce the probability of a conflict, warning systems, such as Intersection Decision Support (IDS) systems, are being developed. These systems alert drivers of SV vehicles attempting to negotiate a left turnabout traffic approaching from the opposite direction. The current paper (i...
