Mapping Equality in Access: The Case of Bogotá's Sustainable Transportation Initiatives

To enhance social equity, three important sustainable transportation initiatives have been introduced in Bogotá. Spatial information and GIS have been used to analyze levels of inequality in access to these initiatives. The results show that the TransMilenio BRT offers equal access for all socio-economic strata (SES). Nonetheless, its modal share is low for the poor due to affordability issues. The Cicloruta bicycle network and Ciclovía recreational program do not offer equal access for all SES, especially for the lower SES. Their users, however, mainly come from low and middle income SES. Marginal network extensions can improve equality in access.

Urban Growth and Transport: Understanding the Spatial Temporal Relationship

This paper describes how public transport and urban growth are strongly related. In fact, there is a reciprocal relationship between transport and urban growth. In order to understand this relationship, it is necessary to analyze urban spatial temporal changes and their related causes and effects. An extensive evidence-based and scientific description of the relationship between urban growth and transport is presented in this paper. This relationship is specifically explored for Jeddah City, Saudi Arabia, applying spatial temporal analysis techniques from remote sensing and Geographic Information Systems (GIS). Spatial and statistical analyses have been used to analyze and relate urban growth and transport spatial temporal indicators. Results indicate a strong reciprocal relationship between urban growth and transport in Jeddah City. The paper found that transport infrastructure expansion strongly correlates with population growth, spatial expansion and land use change. Results also reveal that population growth has increased urban trips and the consequent travel demand, and there is imbalance between travel demand and transport infrastructure supply that explains the increase in congestion. This study also points out a strong significant influence of transport infrastructure on spatial temporal expansion and land use change. It is found that highways and main roads have stronger influence on spatial expansion and land use change in comparison with secondary roads. Although, this study provides significant information for transport and urban development policies, further research is encouraged to use spatial statistical analysis and dynamic modeling to study the reciprocal relationship between urban growth and transport.

Chapter 8 Cycling in Developing Countries: Context, Challenges and Policy Relevant Research

Purpose – This chapter reflects on the role of cycling in India, Sub-Saharan Africa and Latin America, discusses and compares explanatory factors of cycling behaviour and provides three methods of spatial analysis that can feed into local transport policy and planning. n nApproach – The chapter compares important relevant contextual issues and challenges and presents examples of ongoing research on three continents. n nFindings – The findings are in the first instance methodological in nature. Methods have been developed to assess the effect of barriers on access by bicycle, to quantify the avoided carbon emission associated with cycling and to help plan a demand-based cycling network. n nPractical implications – Three different spatial analysis methods are presented: the planning of new bicycle infrastructure, the evaluation of existing cycling in terms of avoided carbon emission and the role of the physical environment in levels of cycling accessibility. The methods can be easily replicated and integrated into transport policy and planning at the local level. n nSocial implications – Effective cycling-inclusive planning in developing countries is expected to lead to higher levels of cycling that positively affect peoples welfare, health and the environment. n nValue of chapter – The chapter affirms that a thorough understanding of physical, social, economic and cultural factors of the developing city context are important in effective cycling-inclusive planning. It provides three relatively simple and replicable methods that are considered particularly appropriate for data scarce developing cities.
