Background The serial correlation in the time series datasets should be considered to
prevent biased estimates for coefficients. Nonetheless, the current models almost cannot …

Driving above the speed limit is one of the factors that significantly affect safety. Many
studies examined the factors affecting the speed of vehicles in the simulated environment …

The relationship between mean speed and crash likelihood is unclear in the literature. The
contradictory findings can be attributed to the masking effects of the confounding variables in …

This study was designed to explore the combinational effect of the roadway and traffic
characteristics of national rural roads on fatal and serious-injury crashes in Namibia …

Rural roads, often characterized by winding paths and nearby settlements, feature frequent
curvature changes, junctions, and closely spaced private accesses that lead to significant …

Numerous research studies have been conducted on modeling operating speed. However,
a crucial aspect that has been largely overlooked is the implementation of these models for …

Traffic-induced air pollutant emissions are currently rising rapidly. However, measurement of
the roadside environment and calculation of the emission factors for traffic-induced PM 2.5 …

Road transport is a major source of environmental pollution. Cars and trucks, which are the
most common types of vehicles, exhaust a variety of pollutants (eg, nitrogen oxides and …

Pedestrians are the most vulnerable road users in traffic accidents. This study analyses the
effective factors in choosing the type of crossing by pedestrians. The required data were …

Road user perceptions and roadway design elements play a vital role in determining the
crash risk level on the roads. The study investigated factors that play a prominent role in …
