Highway-rail grade crossing (HRGC) crash prediction models’ effectiveness hinges on the input data accuracy and precision. This paper investigates the impact of inaccurate HRGC inventory data on the modeling of HRGC crashes. In specific, the research explores existing data gaps by obtaining samples of Federal Railroad Administration (FRA) rail cros...

Safety at the gore areas near diverging ramps is very crucial during planning and implementation of highway safety improvement programs. Limited research has been conducted on safety at the gore areas on arterial roads. This study aims at investigating the impact of improving a sharp gore area in Lincoln, Nebraska by performing a micro simulation b...

This study investigates motor vehicle drivers’ socioeconomic, personality, and attitudinal factors associated with their knowledge of safely traversing highway-rail grade crossings (HRGCs). A three-step mail-based survey of randomly selected Nebraska households solicited responses from licensed drivers (N = 980, response rate = 39%). Of the total 3...

Work zones serve the purpose of facilitating maintenance and rehabilitation activities on roadways. However, these areas can also present unforeseen conditions to drivers, including narrowed right-of-way, lane shifts, and traffic disruptions. These conditions frequently contribute to vehicular crashes within work zones, resulting in property damage...

Road traffic crashes result in significant economic losses for individuals, their families, and entire nations. These losses stem from the expenses associated with injury treatment, as well as the productivity lost due to fatalities or disabilities caused by these injuries. The 2030 Agenda for Sustainable Development set an ambitious target of halv...

Highway-rail grade crossings (HRGCs) are critical spatial locations of transportation safety because crashes at HRGCs are often catastrophic, potentially causing several injuries and fatalities. Every year in the United States, a significant number of crashes occur at these crossings, prompting local and state organizations to engage in safety anal...

The highway–rail grade crossings (HRGCs) crash frequency models used in the US are based on the Federal Railroad Administration’s (FRA) database for highway–rail crossing inventory. Inaccuracies or missing values within this database directly impact the estimated parameters of the crash models and subsequent crash predictions. Utilizing a set of 56...

Highway-Rail Grade Crossings (HRGCs) present a significant safety risk to motorists, pedestrians, and train passengers as they are intersections where roads and railways intersect. Every year, HRGCs in the US experience a high number of crashes leading to injuries and fatalities. Estimations of crash and severity models for HRGCs provide insights i...

Most highway-rail grade crossing (HRGC) crash models in the US rely on the Federal Railroad Administration's (FRA) highway/rail crossing inventory database. Any errors and/or incomplete information in this database affects the estimated crash model parameters and subsequent crash predictions. Using 560 HRGCs in Nebraska, this study illustrates diff...

This study utilized a unique approach to crash data analysis by examining the temporal stability of pedestrian crash injury severity and its contributory factors. Police-reported crash data and EMS-related injury data from Nebraska were obtained from 2014 to 2018, and a random parameter ordered probit model for injury severity was estimated to acco...

This study investigates motor vehicle drivers’ socioeconomic, personality, and attitudinal factors associated with their knowledge of safely traversing highway-rail grade crossings (HRGCs). A survey of randomly selected Nebraska households solicited responses from licensed drivers older than nineteen years (N = 980, response rate = 39 percent). Of...

Highway-rail grade crossings (HRGCs) rank among the leading locations for fatal crashes on the railroad network in the United States, and safety at HRGCs is a top priority for the railroads and the Federal Railroad Administration (FRA). This project studied HRGC safety needs by investigating crash data and HRGC inventory characteristics, and then d...

With the intent to frame policy recommendations for enhancing the state of road safety, this study employed a binary logit regression approach to examine the factors associated with the compliance/defiance of seatbelt use among drivers of different vehicle types in Islamabad. To this end, a questionnaire survey was conducted to collect data on the...

The objectives of the research were to conduct a seasonal investigation of when winter weather conditions are a factor in crashes reported in Nebraska, to perform statistical analyses on Nebraska crash and meteorological data and identify weather conditions causing the significant safety concerns, and to investigate whether knowing the snowfall amo...

Efficiency of an engine decreases over time due to numerous reasons such as excessive heat generation, bad maintenance, outdated cooling system, deformed mechanical parts, oil leakage from seals and hard driving conditions. In this paper, vehicles of a specific manufacturer (Honda Civic I-Vtech Automatic: 2010-2012) were analyzed to comprehend the...

Complex construction projects are risky owing to several features and factors. Their management involves risk assessment which is subjected to various behavioural tendencies and the existing body of knowledge lacks appropriate methods to quantify these effects. The prevalent standard model of Expected Utility Theory does not differentiate between t...

In the present study an analysis of legislation and level of compliance of key crash risk factors (speeding, drink driving, seatbelt, helmet and child restraint) for Islamabad city has been carried out. The data on legislation of key crash risk factors and penalties related to different offenses were obtained from Islamabad Traffic Police (ITP) and...

Peshawar is experiencing an upsurge in traffic related accidents due to an extensive transformation into a city of mobbing, traffic queues, road rage and other traffic related setbacks. This state of mismanagement is owed to several factors, among those driver behavior is one of the most imperative subjects to discuss. Studies on driving behavior a...
