M any transportation agencies are currently involved in computerizing large quantities of gee-based data that have been traditionally relegated to filing systems. The advantages of such computerization include quicker access, more easily understood presentations that result in better interpretations, improved updating capabilities, and a more centralized and controllable source of information. ...

INVESTIGATING THE RELATIONSHIP BETWEEN LATENT DRIVING PATTERNS AND TRAFFIC SAFETY USING SMARTPHONE-BASED MOBILE SENSOR DATA Kenneth Wynne Old Dominion University, 2016 Director: Dr. Rajesh Paleti Crash frequency modelling has been used in the past as an attempt to quantify the expected number of crashes occurring on a certain segment of roadway given a set of variables and factors describing th...

In this study, the generalized estimating equations with the negative binomial link function were used to model rear-end crash frequencies at signalized intersections to account for the temporal or spatial correlation among the data. The longitudinal data for 208 signalized intersections over 3 years and the spatially correlated data for 476 signalized intersections which are located along diff...

We propose a novel vision for roadway safety warning based on sensor networks, aiming at providing user-friendly zero-delay safety warnings to motorists. Our idea leverages the advanced sensing, networking and storage technologies. Roadway sensors detect events and store event records at multiple designated locations along the against traffic direction, such that the passing-by drivers can be a...

most accidents happens because of lack of visibility and not driver’s reaction on time whenan accident occurs. increasing required time for driver’s reaction caused to decreasingaccidents on roadways .intelligent vehicle networks brings enough time for reaction by sendingalert and alternate messages to vehicles on roadway. main propose in this paper is aroundmodulation on reception interval saf...

Compact urban development would reduce urban sprawl, leading to shorter driving distances and ultimately less regional air pollution. But it would also mean greater housing density in a given area, potentially increasing the number of residences near major roadways. Given that exposure to traffic emissions near roadways is strongly associated with asthma and related symptoms in children, a new ...

This paper shows the impacts of human interference on Nile River morphology. A roadway culvert was constructed to connect an island on Nile River to the eastern bank of the Nile had altered river morphology in the vicinity of the island. The paper focuses on, 1) the efficiency of the roadway culvert to pass the normal flow, and 2) the impact of the roadway culvert on river morphology. A one-dim...

For several years the Federal Highway Administration (FHWA) Turner Fairbank Highway Research Center (TFHRC) has been conducting a research program on the effectiveness of roadway delineation for providing enhanced guidance to the driver negotiating curves on rural two-lane roads at night. The FHWA Highway Driving Simulator (HDS), located at the TFHRC, plays an important role in this research pr...

BACKGROUND While several studies suggest that traffic-related air pollutants are detrimental for respiratory health, few studies have examined relationships between residential proximity to a major roadway and asthma control in children. Furthermore, a major limitation of existing research is reliance on self-reported outcomes. We therefore determined the spatial relationship between the distan...

BACKGROUND The emerging consensus that exposure to near-roadway traffic-related pollution causes asthma has implications for compact urban development policies designed to reduce driving and greenhouse gases. OBJECTIVES We estimated the current burden of childhood asthma-related disease attributable to near-roadway and regional air pollution in Los Angeles County (LAC) and the potential healt...
