The availability of reliable transportation is critical to health outcomes, particularly for low-income Americans with chronic health conditions. When lack of transportation impedes medical treatment, chronic conditions can be exacerbated and potentially lead to increased use of emergency medical services. Medicaid’s non-emergency medical transportation (NEMT) benefit seeks to fill in transport...

An analysis was conducted to examine the market visibility of small aircraft as a transportation mode in competition with automobile and scheduled commercial air travel by estimating the pool of users that would potentially switch on-demand air travel due to cost/time saving. These new aircraft greatly increase the practicality of regional aircraft as a transportation mode that can avoid the co...

From 21.03. to 26.03.2010, the Dagstuhl Seminar 10121 Computational Transportation Science was held in Schloss Dagstuhl Leibniz Center for Informatics. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put toget...

BACKGROUND Accurate information is lacking on the extent of transportation as a source of physical activity, on the physical activity gains from public transportation use, and on the extent to which population shifts in the use of transportation modes could increase the percentage of people reaching official physical activity recommendations. METHODS In 2012-2013, 234 participants of the RECO...

objectives : cleaning and shaping of the root canal system is an important step in endodontic therapy. new instruments incorporate new preparation techniques that can improve the efficacy of cleaning and shaping. the aim of this study was to compare the efficacy of mtwo and race rotary file systems in straightening the canal curvature using only one file or the conventional method. materials an...

In China, rapid economic growth and increasing foreign direct investment (FDI) is the driving force for urbanization, and transformation of urban spatial structures and transportation. Frequent interactive economic activities among the neighboring cities reinforce the already spatially clustered cities. In this paper we tried to extract the key urban transportation characteristics of seventy ma...

The National Transportation System (NTS), an outgrowth of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA), is proposed in this research as an analytical tool to guide national transportation policy-making. The NTS must be based upon measures of transportation performance that are intermodal, user-oriented,. and suitable for tracking the environmental, social, and economic o...
