The limits of technology: achieving transport efficiency in developing nations

Emissions from the transport sector represent the fastest growing source of greenhouse gas emissions. There is little prospect that this situation will be resolved with a single technological fix. As developing nations quickly move to catch up with the motorisation levels of developed nations, the sheer number of private vehicles on the roadways will overwhelm any advances made by cleaner fuels. By the year 2030, there is projected to be more vehicles in the developing world than in developed nations. However, most developing cities today still have the basis for a more sustainable future. Public transport and non-motorised transport (walking and cycling) still command a dominant share of travel in developing cities. Thus, a key objective for local and international initiatives is to preserve existing mode shares. Unfortunately, most investment in reducing transport emissions relies exclusively upon achieving costly reductions only through fuel and propulsion system technologies. Bogotá (Colombia) represents one of the best examples of a city that has developed a package of complementary measures to substantially reduce vehicle emissions and congestion. Bogotá’s implementation of a high-quality bus rapid transit (BRT) system, bicycle infrastructure, pedestrian improvements, car-free events, and auto restriction measures all have contributed to an urban transformation in a period of just a few years. Initial projections of greenhouse gas reductions during the first 30 years of the BRT system’s operation indicate reductions of approximately 14.6 million metric tons of CO2 equivalents. This research presents a framework for evaluating the greenhouse gas emission reductions in the transport sector. This framework highlights three principal areas of emission reduction potential: 1.) Mode share (behaviour); 2.) Distance travelled (land-use/design); and 3.) Fuel efficiency (technology). Only by addressing all three components an optimum transport energy path can be achieved

Investing in Mobility: Freight Transport in the Hudson Region

Proposes a framework for assessing alternative investments in freight rail, highway, and transit capacity that would increase the ability to improve mobility and air quality in the New York metropolitan area

Wireless Global Positioning System Fleet Tracking System at the University at Albany

This report provides an overview of the project undertaken at the University at Albany to make alternative transportation a more viable option by implementing a GPS Tracking System on the University bus fleet and broadcasting the bus locations to commuters via the internet and a “smart phone” application. According to a survey administered by the University, students and faculty identified convenience as the number one barrier to taking the bus. In line with its commitment to environmental sustainability, University at Albany wished to increase mass transit ridership by making it more convenient and predictable, thus favorably impacting commuting patterns. This report details the successes and challenges of the project, focusing on lessons learned and suggestions for futureprojects of a similar nature

A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula

This paper’s intended contribution, in terms of providing an additional angle in the existing Bus Rapid Transit (BRT) state-of-the-art knowledge spectrum, is a dual one. On the one hand, it provides a detailed description of the mode, re-defining BRT as an overall concept by identifying, discussing, and categorizing in a systematic way its strengths and its weaknesses in comparison with rail-based solutions and conventional bus services. On the other hand, it presents in detail a number of selected scheme-oriented applications from around the world, looking into some of the basic ingredients behind BRT’s success (or failure) stories. This is a scientific effort that could inform the reader about the current status of BRT internationally and about the challenges and opportunities that exist when trying to materialize BRT’s potential as an effective urban passenger solution that could challenge the merits of more conventional mass-transit options

Making Transport Safer: V2V-Based Automated Emergency Braking System

An important goal in the field of intelligent transportation systems (ITS) is to provide driving aids aimed at preventing accidents and reducing the number of traffic victims. The commonest traffic accidents in urban areas are due to sudden braking that demands a very fast response on the part of drivers. Attempts to solve this problem have motivated many ITS advances including the detection of the intention of surrounding cars using lasers, radars or cameras. However, this might not be enough to increase safety when there is a danger of collision. Vehicle to vehicle communications are needed to ensure that the other intentions of cars are also available. The article describes the development of a controller to perform an emergency stop via an electro-hydraulic braking system employed on dry asphalt. An original V2V communication scheme based on WiFi cards has been used for broadcasting positioning information to other vehicles. The reliability of the scheme has been theoretically analyzed to estimate its performance when the number of vehicles involved is much higher. This controller has been incorporated into the AUTOPIA program control for automatic cars. The system has been implemented in Citroën C3 Pluriel, and various tests were performed to evaluate its operation

A Multi-Vitamin for the Built Environment: Exploring how a Multi-Sectoral and Multi-Institutional Partnership Links Health and the BeltLine

The Atlanta BeltLine is an innovative redevelopment project re-shaping Atlanta residents’ access to, multi-use trails, parks, public transportation, housing and employment opportunities. The primary purpose of this project was to develop a research proposal to study and analyze the health benefits associated with multi-use trails within BeltLine communities. A secondary purpose of this project was to evaluate the multi-sectoral and multi-institutional partnership that was formed to develop the research proposal and study the influence of the BeltLine on health outcomes. In August 2010 representatives from the Centers for Disease Control and Prevention, Emory University, Georgia Institute of Technology, Georgia State University, the Atlanta BeltLine Inc. and the Atlanta BeltLine Partnership formed the BeltLine Health Proposal Committee. Two online surveys using Survey Monkey were conducted to evaluate how this committee was operating, if roles and responsibilities were clear and to determine if this committee was an effective mechanism to integrate health and the built environment. Findings from the survey indicated that committee members believed this group was a unique partnership comprised of dedicated professionals sharing a common interest. Survey findings indicated there were several challenges that needed attention including improving communication, resolving competing interests, and identifying a lead organization. Findings from this evaluation can help resolve these issues and help the committee transition into a Health Advisory Group. The Health Advisory Group will serve as formal body that will review research proposals, conduct research, leverage funding and disseminate key health findings related to the BeltLine

Understanding Commuter Patterns and Behavior: An Analysis to Recommend Policies Aimed at Reducing Vehicle Use

This study focused on the use of single occupancy vehicles by employee and student commuters at the University at Albany. The team conducted a review of the existing options for alternative transportation, developed GIS maps of commuting patterns, investigated the on-time performance of mass transit and created a survey to examine perceptions and barriers to using alternative transportation. The report includes a handbook for conducting a similar analysis at other institutions
