Road transportation poses one of the significant public health risks. Several contributors and
factors strongly link public health and road safety. The design and advancement of higher …

The design input parameters such as vehicular operating speed, deceleration rate and
driver's perception reaction time considered in the geometric design of highways exhibit …

AASHTO's Policy on Geometric Design of Highways and Streets contains geometric design
criteria for horizontal curves for new and major reconstruction. These criteria are based on …

Current design guides adopt a deterministic approach to the design of horizontal curves;
each factor included in the design is represented by the near-worst-case value. In the …

Reliability analysis has been used to account for uncertainties and evaluate the risk of
highway geometric-designs. Despite the existence of correlations between the input design …

Reliability theory has recently been utilized to consider the uncertainty in highway geometric
design and optimize highway cross-section design safety by reducing crash risk. However …

The friction coefficient between the tire and the road is one of the key parameters affecting
road traffic safety. The purpose of this paper is to quantify the risk of skidding for the vehicles …

Highway and street designers deal with the challenge of designing for a broad range of
driver, vehicle, and roadway characteristics and conditions. There is significant variability in …

The high rate of collisions on horizontal curves compared to other roadway elements makes
them one of the most critical elements in a transportation network. In this regard, the current …

A vehicle negotiating a curve experiences a centripetal force that is partially supplied by the
tire–pavement friction. The American Association of State Highway and Transportation …
