Project Selection and Prioritization of Pavement Preservation

Abstract

Several methods help agencies select and prioritize pavement preservation projects. Often these methods are built within an agency's pavement management system. Unfortunately, these decision support tools often produce recommendations that do not match actual decisions, particularly for project selection of pavement management. Ad hoc selection procedures for preservation projects may be effective for many highway agencies. Fiscal constraints and pressure from administrators and legislators, however, have forced agencies to justify their use of funds. This paper offers a new method for the selection and prioritization of pavement projects, with the use of the analytic hierarchy process as its multicriteria decision-making platform. The new method uses several parameters and input from decision makers to create a prioritized preservation project list. The method was applied in a case study in Texas; projects suggested by the method matched actual decisions 75% of the time. The ability to capture multiple parameters and determine weights for each parameter on the basis of decision-maker input, along with the high level of agreement between the method and actual decisions, indicated that the method could be a viable decision support tool.

Research Trends in Pavement Management during the First Years of the 21st Century: A Bibliometric Analysis during the 2000–2013 Period

“…Examples of applied techniques in the period 2012-2013 are the weighting sum method [141], compromising programming [142], analytic hierarchy process [143], the parametric method [144], and genetic or evolutionary algorithms [145][146][147]. Sometimes, two methods are combined to solve an optimization, such as the generic algorithm and the weighting sum method [104,105], or the genetic algorithm and goal programming [148].…”

Evaluating Highway Traffic Safety: An Integrated Approach

“…They were then compared and the grade corresponding to the maximum connection degree represented the grade of highway traffic safety. The results are shown in Tables [14][15][16]. Note that in the equation of fuzzy connection degree (see (10)), i is the coefficient of the discrepancy degree and is specified as 0 and j is the coefficient of the contrary degree and is specified as -1.…”

“…In the transportation field, the AHP has been implemented in numerous applications. The applications include the impacts of transit priority on signal coordination [15], project selection and prioritization of pavement preservation [16], prioritizing network level maintenance of pavement segments [17], assessing options to enhance bicycle and transit integration [18], selection and prioritization of intelligent transportation system user service [19], integration multiple criteria decision making to prioritize transportation [20], assessing asphalt pavement construction quality control [21], analytic minimum impedance surface [22], prioritizing traffic calming projects [23], and determining low volume road standards, long-term needs, and environmental risks [24]. In the area of safety, AHP has been implemented to evaluate railway traffic safety, ship traffic safety, road traffic safety, and work zone safety [9,25].…”

Goal Programming Framework for Prioritization of Low-Volume Road Projects Considering Network Accessibility and Stakeholders’ Preferences

“…Transportation investment decisions are often made, mostly focusing on specific corridors without considering the relationship between the road corridors and the overall transportation network. Gurganus and Gharaibeh used visual distress, traffic volume, and pavement condition as project prioritization criteria ( 2 ). The project selection process did not consider the impact of projects on network accessibility.…”

“…One of the benefits of implementing transportation infrastructure projects is the maximization of network accessibility performance, so that system users’ mobility is optimized. However, infrastructure investment decisions rarely consider the impact of project selection and prioritization on the network accessibility performance and the contribution of each network element (such as a node or a link) to the network’s accessibility performance ( 1 – 3 ). In most cases, transportation investment decisions focus on solving corridor-level transportation problems such as traffic congestion, air pollution, or travel time reduction ( 1 , 2 ).…”
