Risk-based life-cycle analysis of highway bridge networks under budget constraints

Prediction of the severity of exceeding design traffic loads on highway bridges

“…Refs. [ 24 , 25 ], and [ 67 ]). Consequently, compensation fees for overweight trucks have been recommended to balance the economic costs associated with reduced bridge life [ 68 ].…”

“…Refs. [ 24 , 25 , 67 ], and [ 68 ]). Hence, there is little doubt as to how crucial it is that RAs exercise greater vigilance before granting permits for overloaded vehicles.…”

“…Refs. [ 24 , 27 ]); iii) complex impact speed/injury probability models to forecast injury and fatality occurrences and, thus, to derive the related costs (e.g. Ref.…”

Traffic Hazards on Main Road’s Bridges: Real-Time Estimating and Managing the Overload Risk

“…The second direction is numerically inferior and includes papers focused on traffic load hazards. For example, [2] and [21] proposed frameworks to quantify the risk on bridges along highway networks by considering vehicular overload effects and consequent fatigue phenomena. The number of trucks crossing the bridges, the percentage of these trucks that were overweight and the probability that overweight trucks could cross the bridge simultaneously were accounted for in the proposed models.…”

“…The modeling techniques primarily depend on the way in which the risk is intended: there is no agreement among researchers because at least two risk mathematical definitions emerge. The former definition states the risk as the sum of the probability of occurrence of each failure scenario times the associated (direct and indirect) consequences (e.g., [21], [24], [25]). The latter definition states the risk merely as the probability of occurrence of an undesired event (e.g., [26], [27]).…”
