Villalobos Zaid, Macarena Andrea de los Ángeles (Universidad de Chile, 2018)El diseño estratégico de un sistema de transporte público en áreas urbanas se basa en la estructura de líneas (red de transporte público), las flotas, frecuencias y tamaños de bus correspondientes. Un diseño adecuado depende ...

Munizaga Muñoz, Marcela; Jara Díaz, Sergio; Olguín, Javiera; Marshall Rivera, Jorge (Springer, 2011)Origin-Destination surveys, which are regularly conducted in many cities (to calibrate transport models), contain indirect information on individual time use that can be recovered through the declared trip purpose. ...

Jara Díaz, Sergio; Gschwender Krause, Antonio; Ortega Tong, Meisy Andrea (Springer Science+Business Media, 2014)Using a single line model, it has been shown recently that the presence of a stringent financial constraint induces a less than optimal bus frequency and larger than optimal bus size. This occurs because the constraint ...

Cortés, Cristián E.; Jara Díaz, Sergio; Tirachini Hernández, Alejandro (PERGAMON-ELSEVIER SCIENCE LTD, 2011-06)Urban transit demand exhibits peaks in time and space, which can be efficiently served by means of different fleets, increasing frequencies in those groups of stops with larger passenger inflow. In this paper we develop a ...
-
Jara Díaz, Sergio; Vergara, Cristián; Gálvez Pérez, Tristán (TAYLOR & FRANCIS LTD, 2006-07)A new methodology for the estimation of social values of urban air pollution for project appraisal is proposed. This is performed by using individual perceptions (marginal disutilities) of those who are directly affected ...
-
Latournerie Lambertini, André (Universidad de Chile, 2019)Los Sistemas de Bicicletas Compartidas (SBC) han crecido enormemente en la última década. Buena parte de ellos es financiada por agencias de transporte público o mediante recursos públicos, provistos directamente o ...

López Ospina, Héctor A. (Universidad de Chile, 2013)Esta tesis consistió en el desarrollo de avances teóricos en el estado del arte en temas relevantes asociados a la modelación microeconómica del consumidor en el ámbito urbano. En particular se analiza las variaciones en ...
-
Jara Díaz, Sergio; Tirachini Hernández, Alejandro; Cortés, Cristián E. (ELSEVIER, 2008-11)Microeconomic public transport models aimed at maximizing social benefits usually consider demand in an aggregate manner. in this paper we examine the effect of this approach on the optimal values of frequency and vehicle ...
-
Fernández Heredia, Alvaro; Jara Díaz, Sergio; Monzón, Andrés (Springer, 2016)Users’ perceptions are identified as key elements to understand bicycle use, whose election cannot be explained with usual mobility variables and socio-economic characteristics. A hybrid model is proposed to model the ...

Jara Díaz, Sergio; Tovar de la Fe, Beatriz; Trujillo, Lourdes (SPRINGER, 2005-05)Cargo handling in ports is a multioutput activity, as freight can arrive in many forms such as containers, bulk, rolling stock, or non-containerised general cargo. In this paper, the operation of cargo handling firms in a ...
-
Gómez Zúñiga, Valentina Cecilia (Universidad de Chile, 2023)En este trabajo se aborda el Problema de Diseño de Redes de Transporte Público y Determinación de la Frecuencia (que consiste en diseñar simultáneamente una estructura de líneas óptima y sus frecuencias óptimas para una ...
-
Jara Díaz, Sergio; Tovar, Beatriz; Trujillo, Lourdes (2008)Cargo handling activities involve various heterogeneous outputs, e.g. general cargo, containers, dry and liquid bulk and so on. These activities in ports, however, have been usually analysed using aggregate descriptions ...
-
Tirachini Hernández, Alejandro; Cortés, Cristián; Jara Díaz, Sergio (Springer, 2011)We develop a short turning model using demand information from station to station within a single bus line-single period setting, aimed at increasing the service frequency on the more loaded sections to deal with spatial ...
-
Jara Díaz, Sergio; Fielbaum, Andrés; Gschwender, Antonio (Elsevier, 2017)The fleet for surface transit in urban areas - number of buses and vehicle size - is usually determined by the characteristics of demand during the peak period, adjusting frequencies for other periods where those characteristics ...
-
Díaz Hernández, Juan José; Martínez Budría, Eduardo; Jara Díaz, Sergio (SPRINGER, 2008-12)Port workers services have been usually heavily regulated and reserved exclusively for a special kind of workers, dockworkers, which seems to have been the cause of serious inefficiencies worldwide. During the eighties, ...
-
Díaz Hernández, Juan José; Martínez Budría, Eduardo; Jara Díaz, Sergio (SPRINGER, 2008-09)The objective of this research is to measure productivity changes in cargo handling operations in Spanish ports. By means of Data Envelopment Analysis and the calculation of the Malmquist indices we have decomposed those ...
