Abstract: Pavement improvement and capacity expansion traditionally fall in two different decision-making processes. Pavement improvement decisions are typically made at the maintenance level and focus on maintaining, rehabilitating, ...

Abstract: Establishing warrant conditions for auxiliary free right-turn lanes is not only a policy concern but an engineering judgment that should be based on sound engineering principles. This paper presents a new methodology for ...

Abstract: The available design guidelines indicate a lack of proper methodologies for determining the length of left-turn lanes at signalized intersections. This is largely attributable to the alternating nature of stopped and ...

Abstract: Accurate prediction of the pavement crack condition is vital for pavement rehabilitation budget allocation. Due to largely nonlinear surface layer properties, randomness in the cracking mechanism, and the complexities ...
