    Detección de infracciones y matrículas en motocicletas, mediante visión artificial, aplicado a sistemas inteligentes de transporte
    (Associacao Iberica de Sistemas e Tecnologias de Informacao, 2020-06-01) VALENCIA, JESÚS FERNANDO; Ramirez-Guerrero, T.; Castañeda, L.; Toro, M.; Universidad EAFIT. Departamento de Ingeniería Mecánica; Estudios en Mantenimiento (GEMI)
    Incomplete operation of transportation systems has led to an increase in illegal passenger transportation, by the means of motorcycles, at worldwide, causing high accident rates. In the intermediate cities of Colombia, the main control method applied to informal transportation is to impose fines to identified offenders by transit authorities. This work proposes the development of an application that, by means of computer vision, serves as a tool for transit officers in the detections of three infringements types committed by motorcyclists: not wearing a helmet; circulate in prohibited areas; transporting passenger in sites where it’s not allowed. Our case study was Valledupar city, where 105 motorcyclists’ images were taken while they are driving. Results show an accuracy of 87,5% in infringements detection, showing the relevance of this application as an assistance tool to disincentive informal transportation. © 2020, Associacao Iberica de Sistemas e Tecnologias de Informacao.

    Model and solution method to a simultaneous route design and frequency setting problem for a bus rapid transit system in Colombia
    (Sociedade Brasileira de Pesquisa Operacional, 2017-01-01) Martínez F.; Baldoquín M.G.; Mauttone A.; Universidad EAFIT. Departamento de Ciencias; Matemáticas y Aplicaciones
    We propose a model and solution method to a simultaneous route design and frequency setting problem on a main corridor from one of the Bus Rapid Transit (BRT) Systems of Colombia. The proposedmodel considers objectives of users and operators in a combinatorial multi-objective optimization framework and takes into account real constraints on the operation of some Colombian BRT systems not found in previousmodels. The problem is solved heuristically by a GeneticAlgorithm which is tailored from an existing work, to consider specific characteristics of the real scenario. The methodology is validated with current data from one of the most important bus corridors in a Colombian BRT system. The results obtained improve the current solutions for this corridor. © 2017 Brazilian Operations Research Society.

    Representaciones sociales del transporte público en Bello Oriente : malestar urbano, exclusión y salud mental
    (Universidad EAFIT, 2025) Royo Diaz, Sebastián; Guiral Quinchia, Julián Andrés
    This article presents a preliminary analysis of the social representations on public transportation in the Bello Oriente neighborhood (Medellin), identifying factors of psychological discomfort, inequalities in access, long travel times, as well as perceptions differentiated by gender and age. These results allow us to understand possible relationships between public transportation and how it impacts the quality of life in contexts of social exclusion, as well as to raise awareness of these problems, and to promote future interventions.
