Empirical evaluation of change in crash risk due to lane marking reallocation: A case study in Kochi City, Japan
( Elsevier , 2023 , Article)Lane markings are considered an essential component of a road system. As highlighted in previous studies, they are directly linked to efficiency and safety. The rearrangement or reallocation of lane markings can be an ... -
Exploratory study on self-awareness and self-preparedness of Malaysian rail passengers for emergency evacuations
( Elsevier Ltd , 2022 , Article)This study explores the self-awareness and self-preparedness among Malaysian rail passengers during potential emergency evacuations. A questionnaire survey was carried out at a major rail transit terminal in Kuala Lumpur, ... -
Exploring Microscopic Characteristics of Bicycle Riders’ following Behaviors in a Single-File Movement
( MDPI , 2023 , Article)Cycling can bring a wide range of social, economic, and health benefits to individuals and communities. The safety and efficiency of bicycle facilities can be significantly impacted by the interactions among riders. This ... -
Exploring the traveler’s intentions to use public transport during the covid-19 pandemic while complying with precautionary measures
( Multidisciplinary Digital Publishing Institute (MDPI) , 2021 , Article)Public transport use has drastically declined during the COVID-19 pandemic because the virus spreads through close contact with infected people and contaminated surfaces, especially in closed-environments. Evidence suggests ... -
Improved traffic safety at work zones through animation-based variable message signs
( Elsevier Ltd , 2021 , Article)Work zones are established to provide a safe environment for all road users and road workers. However, based on the statistics, they can be considered as crash prone zones due to changes in the road alignments and the ... -
Influence of COVID-19 mobility-restricting policies on individual travel behavior in Malaysia
( Multidisciplinary Digital Publishing Institute (MDPI) , 2021 , Article)The COVID-19 pandemic has resulted in new postpandemic travel patterns as a result of the stay-at-home policies and restricted movement orders imposed by the Malaysian government. The purpose of this study was to investigate ... -
Interactions between autonomous vehicles and pedestrians at unsignalized mid-block crosswalks considering occlusions by opposing vehicles
( Elsevier Ltd , 2021 , Article)Visibility can be identified as one of the critical determinants for the safety performance of autonomous vehicles (AVs) on unsignalized mid-block crosswalks (UMC), which may be significantly influenced by build-up environment ... -
Investigating a university library building evacuation in Pakistan during a semi-announced fire drill
( John Wiley & Sons , 2022 , Article)Evacuation models represent one of the main tools used to assess building fire safety. Existing evacuation models are based on data from evacuation drills in western and developed countries, while there is a need for data ... -
Lane-based analysis of the saturation flow rate considering traffic composition
( Informa UK Limited - Taylor & Francis , 2023 , Article)Saturation flow rate (SFR) is an essential metric for estimating the capacities of signalized intersections. Many factors, including traffic composition, configuration and geometry of the intersection, and driver behavior, ... -
Motorcyclists’ Safety on Expressways: Subjective and Objective Evaluations
( Springer Berlin Heidelberg , 2019 , Article)This study objectively and subjectively investigates the factors influencing motorcyclists’ safety on expressways. The relationships between motorcyclist stress while driving on expressways and potential influencing factors ... -
Pedestrian flow characteristics through different angled bends: Exploring the spatial variation of velocity
( Public Library of Science (PLOS) , 2022 , Article)Common geometrical layouts could potentially be bottlenecks, particularly during emergency and high density situations. When pedestrians are interacting with such complex geometrical settings, the congestion effect might ... -
Pedestrians’ Microscopic Walking Dynamics in Single-File Movement: The Influence of Gender
( MDPI , 2022 , Article)Demographics of individuals could largely influence their behaviors and interactions with surrounding pedestrians. This study investigates the influence of pedestrians’ gender on microscopic walking dynamics of single-file ... -
Relocation of intersection crosswalks to nearby mid-block locations: Simulation-based performance evaluation
( Jordan University of Science and Technology , 2021 , Article)This study explores the performance of an alternative crosswalk design, where crosswalks are removed from the intersections and placed at nearby mid-block to reduce conflicts between turning vehicles and pedestrians. Several ... -
Road Crossing at Unmarked Mid-Block Locations: Exploring Pedestrians’ Perception and Behavior
( Springer , 2022 , Article)Violations, risky behaviors and perceptions may largely contribute to crashes involving pedestrians, particularly at unmarked mid-block locations. The likelihood and severity of crashes at mid-block locations are higher ... -
Role of transport during outbreak of infectious diseases: Evidence from the past
( MDPI , 2020 , Article Review)The outbreak of infectious diseases affects people's lifestyles significantly, as they undertake fewer outdoor activities as a protective measure and to follow government orders of restricted movements. This paper reviewed ... -
