    A two-phase decision making based on the grey analytic hierarchy process for evaluating the issue of park-and-ride facility location
    (2023) Tóth, János; Ortega Ortega, Jairo Fabián; Ortega Ortega, Martín Eduardo; Moslem, Sarbast
    Planning a Park-and-Ride (P&R) system in an urban area of a city depends on a group of transportation planning professionals with different areas of expertise in mobility, agreeing on which criteria or set of criteria are the most important. In addition to analysing the criteria established as mobility policies in the Sustainable Urban Mobility Plan (SUMP), when establishing a set of facilities belonging to the P&R system. To find out which criterion is the most important one when combining the mobility criteria established in the SUMP with the criteria of transportation planners with different expertise, this paper applies the multi-criteria method known as the Grey Analytic Hierarchy Process (G-AHP). In this method, at first the main and secondary criteria are determined at two levels that allow building a hierarchical structure, then transportation professionals are surveyed, and finally, the formulation of the multi-criteria method is designed. The result of the study illustrates the effectiveness and usefulness of the proposed multi-criteria method to determine the hierarchy of criteria from most to least important to solve the problem of locating a P&R system. Also, the results are compared with two different multicriteria methods (FAHP and BWM) to see how they are alike and how they are different. The finding suggests that the planning of a P&R system and the criterion for the accessibility of public transport go hand in hand, regardless of the multi-criteria method employed.

    An integrated multi criteria decision making model for evaluating park-and-ride facility location issue: a case study for Cuenca city in Ecuador

    A park-and-ride (P&R) system is a set of facilities where private vehicle users can transfer to public transport to continue their journey. The main advantage of the system is decreasing the congestion in the central business district. This paper aims to analyze the most significant factors related to a Park-and-Ride facility location by adopting a combined model of Analytic Hierarchy Process (AHP) and Best Worst Method (BWM). The integrated model is applicable for complex problems, which can be structured as a hierarchy with at least one 5 × 5 pairwise comparison matrix (PCM) (or bigger). Applying AHP for at least 5 × 5 PCM may generate inconsistent matrices, which may cause a loss of reliable information. As a solution for this gap, we conducted BWM, which generates more consistent comparisons compared to the AHP approach. Moreover, the model requires fewer comparisons compared to the classic AHP approach. That is the main reason of adopting the AHP-BWM model to evaluate Park-and-Ride facility location factors for a designed two-level hierarchical structure. As a case study, a real-world complex decision-making process was selected to evaluate the Park-and-Ride facility location problem in Cuenca city, Ecuador. The result shows that the application of multi-criteria methods becomes a planning tool for experts when designing a P&R system
