Evaluating Effect of Operating Speed on Crashes of Rural Two-Lane Highways

Journal of Advanced Transportation, 2023
Crashes on a roadway are influenced by various factors, including but not limited to road geometries, traffic volume, and environmental conditions. Among these factors, traffic volume and segment length are commonly used to predict crashes. Recently, the

Study on the length of speed change lanes at the entrance and exit of two-way ten-lane expressways

Frontiers in Built Environment
As the economy continues to develop rapidly, traffic volume on highways has increased dramatically, leading to increasingly severe congestion issues. In response, expanding expressways to two-way ten-lane configurations has become a mainstream strategy ...

Operational Considerations of Passing Zones for Two-lane Highways: Spanish Case Study

Promet (Zagreb), 2018
The U.S. Highway Capacity Manual (HCM 2010) methodology is used in Spain to evaluate traffic operation and quality of service. In two-lane undivided highways, the effect of limiting where drivers could pass slower vehicles, or passing restrictions, is ...

Vision-based lane departure warning framework

Heliyon, 2019
Collisions arising from lane departures have contributed to traffic accidents causing millions of injuries and tens of thousands of casualties per year worldwide. Many related studies had shown that single vehicle lane departure crashes accounted largely

Effectiveness of the Overtaking Ban for Heavy Vehicles on the Four-Lane Divided Highway in Different Weather Conditions

Applied Sciences, 2022
In many European countries and also in Slovenia, the highway network was rapidly built in order to reduce congestion and to increase the level of traffic safety on congested sections of the road network, thus enabling a higher level of service and ...

Analysis and Modelling of Passing Sight Distance Using Vehicle Dynamic Response

IEEE Access, 2023
Passing Sight Distance (PSD) is pivotal for two-lane undivided highways, impacting their safety and operational performance. However, current PSD standards and models are based on simplistic assumptions and do not consider road characteristics and ...

An Exploratory Analysis of Curve Trajectories on Two-Lane Rural Highways [PDF]

Sustainability, 2018
This paper is aimed at obtaining a better understanding of driving behavior on horizontal curves of two-lane rural highways in terms of trajectories in relation to the different curve radii and directions by a driving simulator experiment. The driving simulator experiment involved 50 drivers and eight classes of curve radii, ranging from 125 m to 800 m.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

Biological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Paved Shoulders on Primary Highways in Iowa: An Analysis of Shoulder Surfacing Criteria, Costs, and Benefits, 2001 [PDF]

, 2001
The value of providing paved shoulders adjacent to many higher volume roadways has been accepted in many states across the country. Iowa’s paved shoulder policy is considerably more conservative than neighboring states, particularly on rural four-lane
