La relación entre distribución de equipamientos y servicios en sus diferentes ni-veles de accesibilidad según modos de transporte, muestra una serie de patrones espaciales de movilidad en la ciudad de Los Ángeles (Chile). El estudio analiza la accesibilidad a equipamientos colectivos en modos de transporte, mediante una serie indicadores cuantitativos, utilizando análisis de redes. Se emplean datos de viajes en modos de transporte privado, público y caminata, de la encuesta Origen-Destino (2004). Los resultados evidencian diferencias en la accesibilidad entre el centro y periferia de Los Ángeles. De hecho, la población del centro tiene alta acce-sibilidad, concentrando las mayores y mejores oportunidades. En contraste, la po-blación periférica en crecimiento que, en su mayoría, viaja largas distancias para acceder, especialmente en caminata. Este análisis contribuye a discutir sobre las implicancias de las oportunidades y el papel del transporte en la movilidad de ciu-dades medias de Latinoamérica con un centro preponderante.

Accessibility and the Capabilities Approach: a review of the literature and proposal for conceptual advancements
(TAYLOR & FRANCIS LTD, 2021) Vecchio, Giovanni; Martens, Karel; CEDEUS (Chile)
The Capability Approach, developed by Sen and Nussbaum, has recently gained increasing attention in the transport literature. This paper adds to this growing body of literature by investigating how the approach can generate consistent evaluative approaches to inform (urban) transport planning. The paper reviews the mobility literature that has investigated the Capabilities Approach and identifies the opportunities and challenges of employing the approach as a basis for transport planning. The review highlights the different, and sometimes patchy, ways in which the key notions of the approach have been conceptualised and operationalised. Discussing this growing but scattered literature, the paper embraces the emerging direction that understands accessibility as the capability that transport planning and policy should consider. Further refining this understanding, the paper proposes a twofold evaluative approach combining a top-down and a bottom-up component to capture the myriad of conversion factors shaping people's accessibility-as-capability and functioning. By systematically adopting the Capabilities Approach, transport planning and mobility policies will be directed to enhancing each person's freedom to pursue the life they have reason to value in contemporary societies.

Bus drivers and their interactions with cyclists: An analysis of minor conflicts
(Elsevier Ltd, 2024) Mora, Rodrigo; Waintrub Santibanez, Natan; Figueroa-Martinez, Christian; CEDEUS (Chile)
Driving a bus in a city is a challenging task as it demands paying attention to changing conditions (e.g., weather, congestion) while interacting with passengers and other road users who sometimes display unpredictable behaviours. Cyclists play an important role in these interactions. This paper investigates how cyclists are perceived by bus drivers and how conflicts arising from their daily interactions shape the attitudes of bus drivers. A total of 639 bus drivers (4% of the workforce, 91% males) working in Santiago de Chile responded an online survey. The survey asked drivers about their perception of other transport modes, their experience with traffic collisions and the conflicts they have had with cyclists. Later, logistic regression models were estimated, using “coexistence with cyclists” as the dependent variable. The findings show that younger and older drivers have a better perception of cyclists compared to middle-aged ones. Negative experiences with cyclists worsen the perception of co-existence with cyclists; meanwhile, previous cycling experience was unrelated to drivers’ perceptions. The results also suggest that existing norms are perceived as ineffective. Finally, gender was not statistically significant in shaping bus drivers’ perception of cyclists, yet this topic requires further attention as the composition of the public transport labour force is changing.
Car dependency in the urban margins: The influence of perceived accessibility on mode choice
(2024) Blandin, Lola; Vecchio, Giovanni; Hurtubia González, Ricardo Daniel; CEDEUS (Chile)
Car dependence is a dimension of transport poverty whose subjective components have been limitedly explored. Research on car dependence highlights the incidence of transport costs, assesses the multidimensional vulnerability of car-dependency and the possibility to access valued opportunities. However, people’s perceptions and their perceived ability to access destinations may better reflect the way they move in car dependent settings. In this paper, we aim to examine what are the determinants of perceived accessibility and to which extent perceived accessibility influences mode choices in such areas. Based on a survey carried out in four peripheral and periurban municipalities in the Metropolitan Region of Santiago de Chile, we examine how subjective perceptions of accessibility contribute to explain modal choice in the outskirts. Results show that perceived accessibility has a negative net impact on the utilities for both car and public transport, which means that a low perceived accessibility increases the likelihood of choosing motorized modes. Moreover, residents from peripheral municipalities tend to perceive a higher accessibility than households from periurban areas, who are excluded from the public transport system. These findings show the importance of providing nearby opportunities and convenient alternatives to limit car dependency, especially in periurban areas

Ciclosendas en Renca: la pandemia como oportunidad
(Centro de Desarrollo Urbano Sustentable, 2021) Echiburú Altamirano, Tomás; Hurtubia González, Ricardo; CEDEUS (Chile)
La propagación del COVID19 y la necesidad de garantizar distancia social en el transporte urbano, motivó la implementación de ciclosendas de emergencia en diversas ciudades del mundo. En Chile, la implementación de este tipo de infraestructura quedó en manos municipales, recibiendo escaso y tardío apoyo del gobierno central. La Municipalidad de Renca fue capaz de realizar una de estas intervenciones, la que es analizada en el presente documento.

That the COVID-19 pandemic is unprecedented in terms of its scale, spread and shocks can be evinced by the myriad of ever-changing responses cities all around the world have rolled out throughout the different waves of outbreaks. Although the threat is similar across the world, it took some time before its reach became global and the waves of outbreak are experienced by cities at different times. While this staggered spread imply that some cities might manage the virus better as they learn from the experiences of cities which had been amongst the earliest to face the virus, the reality is more complicated. In the early stages of the pandemic, the global consensus on the best way to contain the virus swiftly converged in the interlinked strategies of restricting the movement of people and minimizing their social contact. However, the effectiveness of these strategies differ greatly between cities. To that end, this study focuses on COVID-19 responses in two regions (Latin America and Southeast Asia) and examines the evolution of the first wave of COVID-19 outbreaks during 2020 in Singapore, Jakarta (Indonesia), Bogot´a (Colombia) and Santiago (Chile). The study is based on a comparative approach and uses a variety of data sources, namely morphology, density, housing concentration, mobility, and governance in the four analyzed cities. The goal is to shed light on the response of city governments in these two different regions in terms of mobility restrictions in order to reduce the cases of new infections. The results show the relevance of urban policies and their territorial approaches, particularly in terms of mobility and public transport networks in the four cities.
Comparing social costs of public transport networks structured around an Open and Closed BRT corridor in medium sized cities
(2020) Proboste Cárdenas,Francisco Javier; Muñoz Abogabir, Juan Carlos; Gschwender Krause, Antonio Enrique; CEDEUS (Chile)
Bus Rapid Transit (BRT) has proven to be an effective and affordable transportation option for large-sized cities. In these cities, BRT is usually considered an effective complement or substitute for rail-based systems, playing a key role in complex multimodal networks with several massive transport corridors. More recently, medium-sized cities of less than 200,000 inhabitants have also considering implementing BRT as a means of mass transit. These cities usually need only a few of these massive transport corridors (often just one), and they must decide how to structure their services. This report discusses which of the two types of BRT-based networks is best for the social interest in the case of medium-sized cities: (1) Closed BRT, in which buses operating inside and outside the corridor are separated and have different designs, or (2) Open BRT, in which the same buses operate inside and outside the corridor, entering and exiting at different points along a route. To answer this question two models with different levels of detail in terms of a city's characteristics were developed to represent both agency and user costs. In the first model a classic idealized city approach is addressed, while in the second model the problem is solved for the specific geographic characteristics and constraints of a real city. The results based on both models show that when it is optimally configured, Closed BRT networks offer mid-sized cities higher frequencies and lower waiting times. However, these benefits do not offset the cost associated with higher number of transfers that Closed BRT networks require, as compared to Open BRT networks. Transfers not only affect users due to the transferring experience, but also end up making the entire system slower. Overall, Open BRT shows significantly less Total Costs than Closed BRT in most of the scenarios that were analyzed.
