Urban mobility and quality of public spaces: the case of Granada, Spain
Grindlay, Alejandro L.; Ochoa-Covarrubias, Gabriela; Lizárraga, Carmen
Different forms of urban mobility have very different impacts on the urban environment and on the quality of the public spaces around them, from the “soft” pedestrian walkways and cycle paths, through the several modes of public transport to the extremely impactful mass use of private vehicles. This paper first analyses the different urban impacts of these forms of mobility, according to their characteristics, with regard to an extensive transport literature review, and they are put into relationship with the factors promoting urban quality and liveability in line with literature on urban design in terms of activity, image and form, among others. The results of this study are contrasted with the experience demonstrated in the case of Granada’s metropolitan area, with its fairly adequate bus-based public transport system and the common mobility problems resulting from a high level of private vehicular use, i.e. congestion coupled with severe environmental pollution. However, a new light rail system (LRT) has been developed, with a major urban renewal along its track, and has proved to be very successful, in terms of the number of passengers, after its two years of operation. The LRT has the particularity of having an underground section, with three underground stations, and longer surface stretches with different cross sections, whereby the improvement in quality of public spaces along them can be evaluated. The high quality public spaces are those with no vehicular access whatsoever, providing a completely pedestrianized area, such as in the traditional urban road crossing axes in the towns, which have been completely freed from vehicles and now seem filled with people, for example Royal Street in Armilla, “Jacobo Camarero” Street in Albolote and “Blas de Otero” Avenue in Maracena, and the section along the university central campus which has no catenary.

Does the mass public transport system cover the social transport needs? Targeting SDG 11.2 in Guadalajara, Mexico
Ochoa-Covarrubias, Gabriela; Grindlay, Alejandro Luis; Lizarraga, Carmen
This paper analyses how SITEUR, the Mass Public Transport System (MPTS) in the Guadalajara Metropolitan Area (GMA), covers transport social needs, contributing to achieve Sustainable Development Goals (SDG) 11.2. In order to facilitate this, an Index of Mass Transport Provision (IMTP) was measured through proximity, frequency, and capacity. Then, an Index of Social Transport Needs (ISTN) was calculated by means of transport disadvantage indicators. Finally, the Index of Social Transport Needs Covered (ICSTN) was calculated. The calculations used geographic information systems and principal component analysis in 1834 geographic sections. Findings highlight that 50.3% of the inhabitants have a very high level of social transport needs, while only 6.8% of the population have very low social transport needs. Results show that SITEUR promotes advancement in public transport systems within the GMA relative to quality, security, and reliability and it also contributes to tackling social exclusion in the GMA. A proposal related to transport systems integration is included, to address an important aspect of social exclusion in the city

Evaluating public transport social exclusion in Guadalajara, Mexico
Lizárraga, Carmen; Grindlay, Alejandro L.; Ochoa-Covarrubias, Gabriela
The role of the public transport system as promoter of social inclusion is gaining increasing attention in the fields of transport policy and planning. This is especially relevant in areas traditionally characterized by high levels of poverty and structural inequalities where it can be a decisive element in the reduction of social exclusion. This paper evaluates the topic through an innovative methodology based on index comparison. Firstly, a traditional accessibility index is used which considers the access time to public transport stops, and secondly an Index of Transport Social Disadvantage is proposed. It includes the transport disadvantage factors of the populations, such as disability, old age, low income, unemployment and pre-school children. These transport disadvantage characteristics have been divided into two groups: the first includes the disadvantage characteristics distributed equally. In the second group, the disadvantaged groups in transport with an unequal territorial distribution are taken into account. The Gini index is used to ascertain the differences in these groups. This method facilitates the identification of the unequal distribution of transport disadvantage and therefore, social exclusion. The consideration of the two indexes, access time and transport social disadvantages, will find the areas not only with low accessibility levels, but also with high levels of population with transport disadvantages, thereby assessing social exclusion linked with public transport. This methodology is applied to the public operated transport system of the Guadalajara Metropolitan Area, Mexico. Its development reveals which areas are affected by the under provision of public transport as well as the population characterized by transport social disadvantage, which together give a clear indicator of the situation of social exclusion linked to the public transport system

(In)equitable accessibility to sustainable transport from universities in the Guadalajara Metropolitan Area, Mexico
Grindlay-Moreno, Alejandro; Ochoa-Covarrubias, Gabriela; DeAlba-Martínez, Hugo
The equitable accessibility to higher education favours social fairness in economic opportunities. This paper provides an empirical approach to the assessment of the (in)equity of accessibility from universities to sustainable transport modes: Light Rail Transit, Bus Rapid Transit, buses, and bicycle infrastructure in the Guadalajara Metropolitan Area (Mexico). In particular, the study designed and calculated an Access to Sustainable Transport from University Index by combining governmental and crowdsourced Open Access Data. It used spatial analysis techniques within a Geographic Information Systems environment, and multivariate statistical methods such as Principal Component Analysis and Cluster Analysis. The findings highlight the weakness in the accessibility to sustainable transport modes from the universities in the Metropolitan Area. Furthermore, this study revealed an unfavourable bias in the location of sustainable transport stations/stops in the vicinity of public universities. The results provide a methodology and empirical evidence for transport policy makers to reduce inequalities and therefore transport-related social exclusion in this under-represented, but socially relevant, student community.
