“…As Newell (1979) noted, when the attractant areas of a city are so concentrated around a central space, the best solution is a radial (or hub and spoke) scheme. However, at the same time, our comparison shows that a grid becomes a better option for scenarios where peripheral areas have more prominence on mobility; this was already advocated by Thompson (1977). In addition, the intermediate hybrid network is in line with the previous arguments of Newell (1979) and Thompson (1977).…”

“…The question is when and where each type of system is the most suitable to serve demand. Thompson (1977) made a simple comparison between four different structures: radial, ubiquitous (the highest degree of a direct trip-based system, where there is a direct line from each origin to any destination), grid and timed transfer (these latter two represent two different transfer-based schemes). The main conclusion was that a transfer-based system offers a better service for peripheral trips than the traditional radial scheme, and, at the same time, it is cheaper than a ubiquitous scheme.…”

This study discusses which transit network structure is the best option to serve urban mobility. As a consequence of the evolution of urban form, cities have undergone a process of dispersion of their activities that has caused a change in mobility needs in the last few decades. Mobility networks and services should progressively adapt to the new demand patterns, especially the bus transit network, which has more flexibility to absorb the changes. We compare four base transit network structures: a radial scheme, a direct trip-based network, and a transfer-based system by means of either a complete grid or a hybrid structure. An analytical model is used to estimate the behavior of these structures for idealized monocentric mobility patterns with several degrees of concentration. The purpose is to determine the right range of situations for the applicability of each bus transit structure, and to determine guidelines about the transit network planning process. It turns out that the best structure is not always the same, and depends on the mobility spatial pattern. A radial network is the best alternative in very concentrated cities; however, a direct trip-based system is more suitable for intermediate degrees of dispersion. A transferbased structure is the best option when the activities are more decentralized. Nevertheless, the decentralization degree that justifies a specific transit structure is not constant. This degree depends on the characteristics of the city, transport technology and users.

“…More frequent runs, extended hours of service, additional safety measures, new park-and-ride facilities, and the extension of routes to outlying areas have long been advocated. Other suggestions include service to large residential complexes and cross-metropolitan routings (Thompson 1977). In addition to these changes, the accommodation of fare structures to multi-purpose trips-particularly work related trips-would be of value to women.…”

RESUMENEste artículo busca dar respuesta a la discusión sobre qué tipo de estrategia de red es la más adecuada: (i) una basada en conexiones directas, u (ii) otra basada en transferencias. En el estudio también se ha introducido el análisis de una red puramente radial, origen de las otras dos. A través de un modelo analítico se comparan los costes totales que implica trabajar con cada uno de los esquemas de red analizados para diferentes escenarios de dispersión de la movilidad urbana. De ello se obtienen los rangos de aplicabilidad de dichas estructuras vinculados a ese grado de dispersión. El fenómeno de descentralización de las actividades ha sido creciente en los entornos urbanos, hecho que dificulta mantener conectada la ciudad a través de redes radiales, e incluso de viajes directos. Esa es una de las principales razones para justificar un cambio de estructura basada en transferencias.A su vez, el artículo incluye la manera en la que los resultados del modelo analítico pueden ser extrapolados a ciudades reales. Es decir, conocido el grado de dispersión de la demanda en una ciudad, poder determinar que estructura de red es más adecuada. Para el análisis de la descentralización de la demanda se parte de la información que aportan matrices origendestino que permiten obtener índices de autocorrelación espacial y de desigualdad. Ambos índices se complementan para conocer la estructura de la ciudad y su grado de descentralización. En este caso, se trabaja con la ciudad de Barcelona, que presenta un grado de descentralización que justifica cambiar a una estructura en base a transferencias. INTRODUCCIÓNEste artículo busca dar respuesta a la discusión existente en el ámbito del diseño de redes de autobús sobre que estructura de red es óptima. Existen dos planteamientos básicos: (i) aquel en el que se defiende conectar de manera directa el mayor número posible de orígenes y destinos, y (ii) aquel que apuesta por una red simplificada donde la sinergia entre líneas a través de transferencias permita satisfacer la totalidad de los viajes.El principal argumento de los defensores del primer planteamiento es la premisa de que los usuarios son adversos a realizar transferencias, hecho que los disuade del uso del transporte público. Es por ello que defienden que deben ser reducidas al máximo, como planteaba Zhao (2006) en su modelo de diseño de redes. Por el contrario, otros autores defienden el segundo planteamiento. Mees (2000) sostenía que una red basada en transferencias es más
