A principal component of maintenance and rehabilitation (M&R) planning is the allocation of
limited funds to candidate projects to achieve optimal levels of system performance. This …

This study is, to our knowledge, the first in the literature to introduce a modeling framework
for analyzing traffic crash frequency based on a series of ensemble machine learning (EML) …

Road infrastructure in appropriate conditions is a requirement for the development of any
country. The formulation of policies oriented to preserve road networks responds to political …

Until recently, statistical approaches used for real-time crash prediction modeling were
limited to case-control design and “sampling of alternatives” approaches. A recent study has …

Lane and shoulder widths are important highway safety factors because wider lanes and
shoulders generally help to reduce crashes. In practice however, due to physical limitations …

This paper proposes a centralized network data envelopment analysis model that combines
the centralized data envelopment analysis model and network data envelopment analysis to …

This paper developed a traffic safety management system (TSMS) for improving safety on
county paved roads in Wyoming. TSMS is a strategic and systematic process to improve …

Planning road safety interventions on large road networks implies several layers of
complexity in the decision-making process. In fact, the following simultaneous problems …

While approximately two‐thirds of the total centerline miles are unpaved in the state of
Wyoming, there is no optimization program for managing these roads. Unlike paved roads …

In the context of highway safety factors, road geometrics and pavement condition are of
particular interest to highway managers as they fall within their direct control and therefore …
