In several cities, bus rapid transit (BRT) systems have begun to experience problems of capacity. Various solutions have been proposed to address these problems, from simple operational modifications to improvements that require modification of the existing infrastructure. Decisions about modification are a challenging undertaking for policy makers; proposals need to he evaluated on the basis of costs (monetary and qualitative or unconventional) and expected returns. For this paper, seven scenarios for Line 1 of the UKT system in Mexico City, Mexico, were structured and modeled to evaluate how operational and level of service improve as a result of (a) operational modifications, (b) investments in infrastructure, and (c) technology acquisitions. Scenarios were modeled by using the simulation tool EMBARQ SimltKT and were ranked by the relative complexity of their execution. Three criteria were used for determining the level of complexity: the cost of implementation, (fie required time, and the administrative process. Results of the scenarios show positive impacts on operation and level-of-service indicators. The paper also reveals that better results are obtained for implementations requiring infrastructure investment than for those involving operational modifications. However, the impact of the proposed implementation is limited; few implementations show progress on the analyzed indicators in a range of 10% variation, giving evidence of the difficulties of improving service. Finally, the paper provides important insights in the decision-making process for transport upgrading, as it describes a methodology to select a proposed improvement on the basis of tradeoff between expected benefits and required administrative process and financial costs.

Urban mobility is not merely a local concern. National governments in developing countries are increasingly investing in urban transport infrastructure. Although the body of knowledge on the topic is growing, further understanding and improvement are necessary. This paper contributes to the topic by providing an assessment and formulating recommendations for the Colombian national urban transport program. The program has increased the number of cities with mass transit from two to eight over the past 10 years. New bus systems, with a total length of 194 km of bus corridors, serve 2.5 million passengers per day. The policy supports smaller cities in transforming their public transport systems citywide. Projects have resulted in positive socioeconomic impacts through reductions in operational costs, travel times, air pollutant emissions, and traffic fatalities and injuries-with a socioeconomic internal rate of return of up to 45%. Two critical aspects for improvement are identified: (a) the competition between semiformal public transport and motorcycles and organized public transport and (b) the principle of self-sustainability of transit systems. Suggestions on policy responses, such as stronger focus on quality, subsidies-funded from transport demand management and land use value capture-and enhancement of institutional coordination and control, are presented. Lessons from Colombia are relevant to other emerging countries that arc considering and upgrading national urban mobility policies.
