Public transportation systems in many cities of Latin America must employ physical architectures of intelligent transportation systems for the operation and control of passenger transportation vehicles. However, the high cost of specialized computational systems for this physical architectures in one of the higher impediments to the integration of this systems in the vehicle network. For the purpose of this work, is necessary to ask what are the currently low-cost computational systems used in vehicular applications. In this paper we made a documentary research to analyse the current computational systems associated with the physical architecture for public transportation in intermediate cities. We analysed collected information following the three points of methodological development for a documentary researches. Results shows that the use of low-cost computational systems for data capture in vehicles, the use of millimetre waves in the electromagnetic spectrum for data transmission by means of mobile communication networks, and the adoption of international standards, are viable alternatives for the integration of technologies into physical architectures of vehicle networks, in order to improve the operation of public passenger transportation systems in intermediate cities in Latin America.
Public Transportation Strategic Systems are a digital transformation for the urban transportation service in the Colombian medium-size cities, from 200,000 to 600,000 inhabitants. The implementation of the urban public transportation services has not started in many cities; as a result, this cities in Colombia have an increase of illegal motorcycle taxis, which cause a high number of road accidents. The main method for controlling illegal motorcycle taxis is by giving the drivers transit fines. In order to give such transit fines, transit police have several control points in medium-size cities. In this article, we developed a mobile application to detect three types of transit infractions usually committed by motorcycle taxi drivers. The purpose of this application is to be a tool for the transit police agents to disincentivize the use of motorcycle taxis. The mobile application detects a possible transit infraction, saves the photo, motorcycle plate number, date, and time. Afterwards, the application generates a support for the transit infractions that will be issued by the transit police officer. We performed an experiment using this mobile application in the city of Valledupar, Colombia. The mobile application captured 40 possible transit infractions.
Resumen: El funcionamiento incompleto de los sistemas de transporte ha propiciado el incremento del transporte ilegal de pasajeros mediante motocicletas a nivel mundial, causando altos índices de accidentalidad. En las ciudades intermedias de Colombia, el principal método de control aplicado al transporte informal consiste en imponer multas a los infractores identificados por las autoridades de tránsito. Este artículo propone el desarrollo de una aplicación que, mediante técnicas de visión artificial, sirva como herramienta para los oficiales de tránsito en la detección de tres tipos de infracciones cometidas por motociclistas: no usar casco de protección; circular por zonas prohibidas; transportar parrillero en lugares donde no está permitido. Nuestro caso de estudio fue la ciudad de Valledupar, donde se tomaron 105 imágenes de motociclistas mientras conducían. Los resultados muestran una precisión del 87,5% en la detección de infracciones, mostrando la pertinencia de la aplicación como herramienta auxiliar para desincentivar el transporte informal.
In the last ten years, approximately, urban transit systems of Latin American capital cities have evolved significantly. Colombia, specifically, has concentrated this development in its capital cities, consolidated through digital transformation programs in the transportation sector. However, the same phenomenon does not occur in medium-sized cities for different reasons that are important to analyze. This paper presents an exploratory qualitative study involving eight medium-sized cities in the implementation phase of their strategic urban transit systems. Three main aspects that drive this study were identified: technologies and their cost, functional requirements to implement information technology services in transit systems, and economy and administration associated with this type of implementation. Based on this, a semi-structured interview data collection instrument was designed, with the participation of 15 officials distributed in the eight target cities, and one expert from an intelligent transportation system in a capital city. With the information collected, an exploratory analysis was made contrasting the responses given by each interviewee. The most relevant results show that the interviewees prioritize technologies based on open standards to provide information to users; that the northern medium-sized cities of the country do not have strategies that regularize and motivate the use of public transportation; instead, the southern medium-sized cities of the country consider the use of transportation to be necessary. Finally, it was concluded that the information technology services to be included in the provision of transit services should promote these cities’ cultural and economic growth.
