In practice, the process of transportation planning is shaped by more than technical factors. This paper analyzes how different factors (demand, local conditions, financial, social, and political) have influenced all of the rapid transit projects in Ecuador over the past three decades by evaluating their relative significance on each system component (alignment, size, and technology). This research uses a multiple-case methodology including in-depth interviews with the senior members of the technical teams, as well as a survey component based on the analytic hierarchy process for quantification of the relative significance of the factors. The comparative analysis of projects shows five key results: (1) Each project was unique and external factors introduced a varying degree of complexity into each planning process; (2) The systems’ alignments and sizes were mostly driven by demand and local conditions (rational planning process); (3) The main factor driving technology selection has evolved over time from system demand to political (political bargaining approach); (4) Negative economic conditions had a large influence on the factors of all project components; (5) There is a lack of rational alternative evaluation and an absence of corresponding tools/guidelines in Ecuador. Nonetheless, several processes included practices that contributed to a more rational planning process: lifecycle cost analysis for the various technology alternatives, explicit decision-maker guidelines, transferring the demand risk to the private sector, and the use of multicriteria decision analysis. Implications for future planning efforts are discussed.

“…How to select the suitable service under certain condition has been discussed through different aspects. The common approach is to compare the cost or operational efficiency (Smith, 1973;Allport, 1981;Stutsman, 2002;Stutsman, 2002;Bruun, 2005;Jara-Díaz and Gschwender, 2009;Tirachini et al, 2010a;Casello, 2014). Recently, some researchers started to explore this issue in detail with optimized parameters of transit lines.…”

This paper develops an analytical model to support the decision-making for selection of a public transport service (PTS) provision between park & ride and on-demand public bus (ODPB). The objective of the model is to maximise the total social welfare, which includes consumer surplus and operator's net profit. The model is solved by a heuristic solution procedure and tested on an idealized linear travel corridor. The case study considers the effects from population density, density distribution, size of residential area, P&R station location, distance from the residential area to centre business area (CBD), as well as the changes of residential area layout and population growth. Results show that P&R fits for low population density area while ODPB is more suitable for high population density area. Population distribution type has little influence on the services' social welfare. ODPB is a preferable service for the city which does not have advanced metro network. The investment time for building ODPB service in the planning horizon is discussed at last with consideration of the development of residential area.

“…Parajuli and Wirasinghe (1991) proposed a two-stage approach for selecting transit modes by considering subjective factors and other cost parameters. Several more recent studies (Casello et al 2014, Sivakumaran et al 2014) also analyzed the selection of suitable transit modes, for given demand characteristics and financial concerns. Usually, a single transit mode was selected in those studies without considering the feeder-trunk structure.…”

“…A few more studies are available on the selection of the optimal transit mode, i.e., identifying under what conditions a transit mode is preferred to other alternatives. Casello et al (2014) present a method for selecting between the bus rapid transit and light rail transit through computing the life-cycle costs for candidate systems. In a case study conducted for Waterloo, Canada, they find there are no significant cost differences between two modes (bus rapid and light rail) and small changes in assumed inputs can reverse the preference.…”

This paper explores how the selection of public transit modes can be optimized over a planning horizon. This conceptual analysis sacrifices geographic detail in order to better highlight the relations among important factors. First, a set of static models is proposed to identify which type of service, e.g., bus only, rail only, or bus and rail, is the most cost-effective in terms of the average trip cost for given demand. After analyzing essential factors in a long-term planning process, e.g., economies of scale in rail extension and future cost discounting, a dynamic model incorporating such considerations is formulated to optimize the decision over a planning horizon. While analytical solutions can be obtained for some decision variables, the final model is solved with a graphical method by exploring the tradeoffs between the initial and recurring costs. Major findings from this study include: (a) there exists a minimum economic length for a rail line, which can be determined numerically; (b) economies of scale favor large extensions and excess supplied capacity; (c) the rail-only service is largely dominated by the feeder-trunk service, even in the long run.
