The present highway geometric design is governed by design speed and considers all other
variables such as terrain, roadway, and driver characteristics as deterministic. The behavior …

Reliability analysis has been advocated as a robust methodology to quantify the risk (known
as the probability of non-compliance, P nc) associated with design limitations such as …

The current study proposes a modified reliability theory and methodology for the speed-
based evaluation of successive geometric elements such as a long tangent followed by a …

This paper expands the scope of geometric design inconsistency analysis from corridor
scales to network-wide perspectives, exploring the impact of inconsistencies' spatial …

The main objectives of the present study are to calculate the reliability index as a function of
sight distance and corresponding provide some possible geometrical improvements …

Abstract Objective Current Road geometric design processes disregard stochastic aspects,
resulting in inadequate traffic safety considerations. In addition, the primary sources of crash …

Road safety on horizontal curves has become a great concern due to issues related to the
number of road crashes where collisions result in twice as many fatalities as on a straight …

Horizontal curves of rural roads are accident-prone segments of the route. Sharp curves,
steep slopes, and reduced visibility due to the mountainous environment greatly affect the …

Abstract Although Autonomous Vehicles (AVs) are quickly becoming a reality, there is much
that needs to be understood before mainstream commercialization can occur. One critical …
