Book Description
Most cities of the Latin America and the Caribbean region face similar problems, including low quality public transport supply, lack of planning, congestion, and both atmospheric and noise pollution. As a response to these growing concerns, many governments are implementing actions aimed at encouraging the use of more sustainable transport modes and reducing transport dependence on the private car. Despite the advances gained through the implementation of these and other policies in LAC, there is still a long way to go, especially in the promotion of seamless transport systems at the city level, the achievement of financial sustainability, as well as the improvement of urban air quality. This study identifies a number of best practices for overcoming or working around these challenges.

Book Description
Fast growing economies are paralleled with extensive sprawl and an increasing trend in auto-mobilization. Hence there is a direct effect on the travel demand on transport systems. Cities are confronted by challenges to achieve sustainable alternatives to the benign effects of the private motorcar. The move from an auto-oriented city towards a lesser car reliant city is of dire need. The ways in which people travel have an enormous impact in the urban morphology and also in urban transport systems. Travel patterns are characterized by the trip length, trip time, and trip rate; especially the purpose of travel determines the mode share preferred. Sustainable systems are aimed at reducing over consumption of fossil fuels and land cover therein reducing the emphasis of the private automobile as the primary mode of transport and encouraging shifts towards sustainable modes such as cycling, walking and public transit. The focus of this paper is on the promotion of sustainable urban transportation through the integration of non-motorized transport systems (cycling, walking) with public transport network systems. A hybrid evolution, an outcome of the synergy between two modes of transport - namely the bicycle and public transport, is an evidence of two complementary transport modes that would cater to diverse individual travel needs in a quick, efficient and sustainable manner. The current public transport system - the bus rapid transit system of Ahmedabad in the context of a developing country, India is comparatively studied with bus rapid transit system of Curitiba, Brazil. A primary survey is done to analyze the inclination of commuters to shift from their private modes to the BRTS. Existing travel patterns of the city of Ahmedabad are studied to help predict the preferred modal choice and to understand people's behaviour to switch to other modal choices. The pre-conditions and post- conditions are also considered. Some areas of implementation are observed in detail to represent and communicate the issues of its un-sustainable impacts in the urban environment. The current state of the BRTS of Curitiba is compared to perceive what can be learnt from and what can be implemented in the Indian context, as the BRTS model of Curitiba was one of the earliest implemented BRT system that is functioning very efficiently. When scrutinizing the two scenarios, it shows that executing the BRTS can increase sustainable mobility to a certain extent. In the Indian context, the BRT system can be considered as a step towards implementing sustainable alternatives to the existing deterrent environment. This is done by addressing my hypothesis of how effective planning policies are, in its implementation of the integration of NMT with public transit systems.

Book Description
The introduction of emerging transportation technologies, such as mobility-on-demand and shared modes, have caused disruptions in urban transportation systems. These services brought multiple challenges, including the lack of infrastructure, arbitrary pricing schemes, deficient operating rules and regulations, and safety concerns. Furthermore, the deployment of these technologies has increased the need and demand for improved management of the associated data. In particular, the volume of the collected information, the variability of data sources, the heterogeneous structure, and the inherent spatio-temporal nature highlight challenges for finding spatial and temporal relationships, dealing with computational complexity, and for the integration or fusion from various sources. This research work is based on the need for the implementation of models and methods for dealing with large-scale, diverse, and spatio-temporal datasets to adequately characterize emerging mobility technologies and their potential impacts on urban environments. Specifically, it assesses three main points: (1) the impact of emerging mobility modes on urban areas is still unknown, (2) it is not clear what is the effect of shared mobility services on public transit usage, (3) when available, the data may present several challenges. This dissertation designs and applies models and methods to evaluate emerging mobility services' impacts on different aspects of urban areas. The impacts in question are analyzed using four distinctive techniques based on advanced statistics and data analysis models and methods. These techniques are applied to several data sources describing ridesourcing (i.e., ride-hailing via transportation network companies or TNCs), microtransit (i.e., privately owned and operated shared transportation system that can have fixed or flexible routes and schedules), micromobility (e.g., bikesharing and dockless electric scooters or e-scooters), and public transit trips from Austin, Texas. The results of the analyses show that the current fare system and pricing strategies can lead to disparities in TNC driver earnings. Temporal and spatial demand variations can exacerbate search frictions, which can cause an overall market failure. The results suggest that new pricing strategies are required and that there is a need for pricing regulations. A further examination of the ridesourcing effect on the airport ground access using Intelligent Transportation Systems (ITS) showed that the average airport-accessing speed decreases in the presence of TNCs. The use of ITS data is proposed to support airport decision-making processes. Finally, this study analyzed the integration of shared modes with the public transit system. Shared modes can complement the public transportation systems (like bus, train, and air) and solve first-mile-last-mile (FMLM) accessibility issues. However, this study's results suggest that this integration is not yet happening for TNCs and microtransit modes. An analysis of the use of Public-Private Partnerships (PPPs) to introduce share modes in areas with low public transit demand suggests the service was mainly used for intrazonal trips and not for FMLM. Further analysis of the relationship between e-scooters and public transit was able to identify areas with potential e-scooter and bus interaction. The results suggest that future collaborations and PPPs should focus on integrating these mobility services into the public transit system
