A Fuzzy Logic-Based Approach for Estimation of Dwelling Times of Panama Metro Stations

Abstract

Passenger flow modeling and station dwelling time estimation are significant elements for railway mass transit planning, but system operators usually have limited information to model the passenger flow. In this paper, an artificial-intelligence technique known as fuzzy logic is applied for the estimation of the elements of the origin-destination matrix and the dwelling time of stations in a railway transport system. The fuzzy inference engine used in the algorithm is based in the principle of maximum entropy. The approach considers passengers' preferences to assign a level of congestion in each car of the train in function of the properties of the station platforms. This approach is implemented to estimate the passenger flow and dwelling times of the recently opened Line 1 of the Panama Metro. The dwelling times obtained from the simulation are compared to real measurements to validate the approach.

Improving High-Frequency Transit Performance through Headway-Based Dispatching: Development and Implementation of a Real-Time Decision-Support System on a Multi-Branch Light Rail Line

“…Although trips complying with the optimized departure times from the decision-support system improved service quality, only half of the trips were dispatched close to the recommended times. Improving location predictions could help predict service deterioration and thus improve the effectiveness of a control policy, especially in very high-frequency services (22,23). The human factors contributing to non-compliance, including those related to technology and culture, should also be studied in depth.…”

Applying Time-Dependent Attributes to Represent Demand in Road Mass Transit Systems

“…They are used to predict the demand variations that occur daily in the transport network, for example, and are represented by the O–D matrix containing the mean value and the standard deviation [ 7 ]. An alternative approach to determining passenger flow using the O–D matrix was proposed by Berbey [ 8 ], using fuzzy logic to determine the values of its elements on a public transport metro system.…”

The R and D activity as a supporting tool for the active teaching and learning methodology in an engineering course

“… Publications in scientific international congress [48][49][50][51]  Publications in scientific indexes journals [52][53]  Publications in international Professional magazines [54]  Publications in scientific-technical magazines [55][56][57] R&D Project: "Methodologies and Performance Indexes for railroad systems" [45][46][47] Construction of the content subject Fig. 2.…”

“…dissemination of the results of research [45][46][47][48][49][50][51][52][53][54][55][56][57] occurs as a consequence of convergence of complementarity between teaching and research activities studied by authors like: Perdomo [63], Mitchell et al, [64] Tesouro et al, [65] and Molina [66]. In other words, the results of the research activity [45][46][47][48][49][50][51][52][53][54][55][56][57] are transformed in new contents in the teaching activity. These are the new didactic resources.…”
