The estimated cost impact of privatizing Student Transportation in Minnesota school districts
Public Choice, 2011Co-Authors: Owen ThompsonAbstract:Student Transportation makes up a substantial portion of a typical school district’s operating budget, and sub-contracting bus service to private firms has been advanced by some as a way to reduce Transportation costs. Previous studies have found conflicting evidence regarding the cost impact of privatization. This paper seeks to improve on previous studies by estimating cost equations using data that spans six school-years. The primary result is that privatization acts to substantially increase Transportation costs. Estimates using a pooled cross section predicted that going from fully outsourced to fully in house reduced costs by approximately 15.8%, while the analogous estimate using a first-differenced equation was a savings of 20.7%.

model for optimization of locations of schools and Student Transportation in rural areas
Transportation Research Record, 2012Co-Authors: Pablo Mandujano, Ricardo Giesen, Juancarlos FerrerAbstract:Low population densities make it difficult to design efficient networks of schools in rural areas. The most common solution is to operate small schools with children in multiple grades in each classroom, even though this solution may not be the least expensive. School consolidation proposals are difficult to implement because communities may have emotional bonds with their local schools and the impacts on secondary services, such as Student Transportation, are difficult to evaluate. In rural areas, particularly in Brazil, reductions in the costs associated with school operations and Student Transportation could allow boards of education to allocate more resources to improve educational practices and teaching materials. This paper presents a methodology for optimizing the location of schools and Student Transportation in rural areas. This methodology is based on two mixed-integer programming models, which are used sequentially. The first one deals with the school location and sizing problem, and the second one deals with the school bus routing and shift programming problem. The methodology was applied with data from Barao de Grajau, which is in the northeast region of Brazil, and provided savings in operating costs of 10% to 17%.

the project of school bus safety in bangkok metropolis mode of Student Transportation
Vajira Medical Journal (วชิรเวชสาร), 2011Co-Authors: Busaba Suppawattanabodee, Anan Manomaipiboon, Moanawt Ngerncham, Premwadee KaruhadejAbstract:The Project of School Bus Safety in Bangkok Metropolis: Mode of Student Transportation Busaba Suppawattanabodee MSc (Biostatistic)* Anan Manomaipiboon MD, MSc (Clinical epidemiology)** Mo a nawt Ngerncham MD, MPH (Epidemiology)** Premwadee Karuhadej EdD*** * Clinical epidemiology unit, BMA Medical College and Vajira hospital ** Department of Surgery, BMA Medical College and Vajira Hospital *** Kuakarun Nursing College Objective: To identify the modes of Student Transportation in Bangkok Metropolis. Design: Cross-sectional analytical study. Subjects: A total of one hundred and thirty four schools with 17,499 Students from kindergarten to mattayom and also their parents were randomly selected by using multistage stratified random sampling. Main outcomes measurement: The number and percentage of mode of Student Transportation. Method: This study was conducted during the period of March 2003 until February 2004. Self-administered questionnaires were distributed to the samples. Results: The three popular modes of Student Transportation were personal car, motorcycles and public buses with responsible to 22.0% (95%CI: 21.2-22.6), 21.1% (95%CI: 20.5-21.7) and 16.2% (95%CI: 15.6-16.7). The estimated number of Students going to school by school bus was 7.3% (95%CI: 6.9-7.7). Conclusion: School bus services was not popular in Bangkok Metropolis corresponded with the estimated number of Students going to school by school bus was 7.3% (95%CI: 6.9-7.7).

a testbed experiment of a smart marked based Student Transportation policy non convexities coordination non existence
Social Science Research Network, 2017Co-Authors: Hsing Yang Lee, Travis Maron, Charles R Plott, Han SeoAbstract:The paper develops and studies a decentralized mechanism for pricing and allocation challenges typically met with administrative processes. Traditional forms of markets are not used due to conditions associated with market failure, such as complex coordination problems, thin markets, non-convexities including and zero marginal cost due to lumpy Transportation capacities. The mechanism rests on an assignment process that is guided by a computational process, enforces rules and channels information feedback to participants. Special, testbed experimental methods produce high levels of efficiency when confronted by individual behaviors that are consistent with traditional models of strategic behavior.
