Bad air quality due to free pollutants such as particulate matter (PM), carbon dioxide (CO 2),
nitrogen oxides (NO x) and volatile organic components (VOC) increases the risk of long …

Through introducing a generalized optimal speed function to consider spatial position, slope
grade and variable safe headway, the effect of slope in a single-lane highway on the traffic …

Unsignalized mid-block raised crosswalks have been adopted as inclusive transport
strategies, providing humps to reduce vehicles' speed to promote drivers to yield to …

In this paper, an extended cellular automaton model is proposed to simulate the complex
characteristics of traffic flow and the probability of the occurrence of traffic accidents by …

Arrays of baffles are usually installed in front of protection site to attenuate the flow energy of
rock avalanches in mountainous areas. Optimization design is crucial for efficiency …

As a common transportation facility, speed humps can control the speed of vehicles on
special road sections to reduce traffic risks. At the same time, they also cause instantaneous …

In this paper, we propose a novel slope cellular automaton (CA) model to depict some
physical properties of traffic flow with slopes. In our model, we present the effect of slopes on …

In the fixed-block railway traffic, the trains adjust their speeds in view of their preceding
allowable spaces caused by their respective front adjacent trains or specified by scheduling …

Speed bumps are extensively used to regulate speed and improve traffic safety. Speed
bumps can also affect traffic characteristics significantly. Aiming to explore the impact of …

The installation of speed bumps on the roads aims to improve traffic safety by forcing vehicle
to decelerate. The actual deceleration effectiveness of speed bump is closely related to …
