Over speeding is one of the most common factors contributing to road accidents leading traffic-related injuries and deaths. Understanding determinants over behavior an important step toward enhancing safety developing robust intervention strategies. Moreover, there a need extend this knowledge with respect countries, where significant variation in operating speeds vehicles owing heterogeneous traffic conditions. The present study captured Mumbai, India, during years 2017 2018 using roadside...
When signal changes from green to yellow at a signalized intersection, often drivers become skeptical, whether cross the intersection or stop without entering intersection. Improper decision might lead right angle collision rear end collision. The area in which are skeptical is termed as dilemma zone indecision zone. Most of studies literature have investigated driving behavior homogeneous traffic conditions, but developing countries like India heterogeneous containing various vehicle types,...
Crashes take place at intersections even when signalized due to the presence of dilemma zone, where driver feels uncertain whether cross or stop trigger yellow signal. Erroneous decisions taken by leads rear-end right-angle crashes, causing safety implications. Accurate position zone can help in implementing various measures and enhance intersections. This study evaluates boundaries for mixed traffic conditions using Support Vector Machine (SVM), a supervised machine learning technique. The...
Roads network is composed of mid-blocks and intersections.The part where two roads cross called an intersection whereas the straight sections without or any other interuptions mid-block.It can be observed that vehicles on tend to achieve their free-flow speeds while those at intersections are forced decelerate.Modelling these needs separate from mid-block.Further, drivers behave differently locations.Present study attempts zone influence (IZOI) mid-block using manoeuvring characteristics in...
The indecisiveness of drivers at the yellow onset creates a dilemma zone (DZ) upstream signalized crossings. light negatively influences intersection safety, often leading to rear-end and right-angle collisions. This study explores impact road marking active in-vehicle warnings designed based on DZ boundaries. prototype concepts warning systems were implemented in driving simulator environment. driver responses from experimental setup captured evaluate effectiveness countermeasures. Study...
This study comprehensively investigated the factors affecting crash injury severity associated with commercial motor vehicles (CMVs), that is, large trucks and buses, on Interstate-65 (I-65) in state of Kentucky. Unconventionally explored microscopic real-time weather variables (i.e., air temperature, relative humidity, solar radiation, wind speed, precipitation) were extracted from 80 mesonet stations Kentucky used analysis. Other included hourly traffic volume speed driver-, roadway-,...
This study develops safety performance functions (SPFs) for severe (“KA” or “fatal and suspected serious injury”) distraction-related crashes along Kentucky’s rural urban two-lane undivided roadway segments using recent four-year (2018–2021) crash records. Additional efforts were made to meticulously scrutinize narratives categorized as non-distracted correct those cases. To account under-dispersion, the Conway–Maxwell–Poisson, heterogeneous zero-inflated Conway–Maxwell–Poisson (ZI-HTCMP)...
This study investigates and compares the pattern of distraction-related crashes pre-COVID-19 pandemic (2018–2019) post-COVID-19 (2020–2021) in Kentucky. Comprehensive crash (i.e. manner collision, at-fault vehicle type, time crash), driver age), roadway type), environmental weather condition) characteristics were investigated contrasted pre- post-pandemic. The systemic safety analysis showed that pre-pandemic, severe mostly occurred along urban undivided two-lane roads with 30–40 mph speed...
Adverse weather conditions can be hazardous for driving, especially along high-speed interstate facilities. Despite the significant impact of on traffic safety, relatively few studies have documented effects real-time crashes. This study investigates weather-related factors crash severity Kentucky's Interstate 64 (I-64), 65 (I-65), and 75 (I-75). Recent five years four months crashes (January 1, 2016, through April 30, 2021) three aforementioned interstates were collected from Kentucky...
