Low-cost computational systems applied to physical architectures in public transportation systems of intermediate cities

Abstract

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.

Characterization of variables for modeling agroclimatic and phytosanitary events in agricultural crops using deep learning models

“…This study is based on an exploratory type of documentary research, adapted from the methodological proposals followed in the research conducted by [9][10][11][12]. Based on these proposals, a qualitative analysis of the data obtained from studies related to the modeling of agroclimatic and phytosanitary events in agricultural crops, the analysis and critical review of research articles, and the analysis and critical review of the results of the studies were conducted [13,14].…”

Key Aspects for IT-Services Integration in Urban Transit Service of Medium-Sized Cities: A Qualitative Exploratory Study in Colombia

“…For Colombian MSC, the criteria with the greatest influence on transportation mode selection for users are walking and waiting time [26]. Thus, several research works were developed to design technological solutions and best practices to improve service provision in UTS, such as (a) automatic detection of traffic infractions [27,28], (b) evaluation of transit drivers [29], and (c) identification of functional requirements of low-cost IT systems to optimize the performance of UTS in Colombian MSC [30,31]. From another perspective, [32] presented other solutions aimed to promote the daily use of non-motorized means of transportation, and to encourage the improvement and sustainability of mobility in an MSC.…”

“…Currently, there are low-cost IT alternatives for UTS that can meet the desired requirements for UTS of the MSC studied. Proposals such as (i) use of smartphones and mobile applications for vehicle and user data capture [31,52,53], (ii) use of information collected by vehicle sensors through the onboard diagnostic (OBD) interface [31,54], and (iii) use of low-power, wide-area open communications networks [38,55], are examples of technological solutions with a low-cost approach that can supply the IT requirements, in UTS, in MSC for a SETP.…”

Agroclimatic and Phytosanitary Events and Emerging Technologies for Their Identification in Avocado Crops: A Systematic Literature Review

“…Recently, the fourth industrial revolution (4IR) has influenced a broad spectrum of industries and sectors through the introduction of new technologies, mainly in economic activities of the secondary sector (manufacturing, clothing, construction) and the tertiary sector (transportation, maintenance, marketing, communications), to reduce inefficiencies and improve market performance [13][14][15][16][17][18][19][20]. Similarly, the agricultural industry is experiencing a growing presence of digital transformation, attributed to the advancement and accessibility of information technologies (ITs) tailored to this domain.…”
