The city of Chennai with over six and a half million people is the fourth largest on the subcontinent and has already been a prominent city of interest in the specialty＇s development. However, there is no standardization of the resources found in the city＇s emergency departments. This study was to survey the equipment, training, and certification of Chennai area emergency departments and their staff. METHODS：We conducted a cross-sectional survey of emergency department staff from 38 Chennai area hospitals. The survey instrument contained 44 questions pertaining to hospital demographics, staff training and certification, and ED equipment and supplies. The items on the survey were specifically chosen to represent only the most basic and common resources necessary to practise emergency medicine. RESULTS： The survey found a majority of hospitals are privately operated but there is a wide range in terms of size and volume of patients. A minority of both doctors and nurses are certified in BLS, ACLS, PALS, and ATLS. While almost all departments surveyed had the basic code medications, a number of basic equipment items were lacking from a large percentage of the EDs surveyed. CONCLUSION：The newly established EP community in Chennai will have the responsibility to establish standards for both training and resources so that the specialty may grow and provide a higher standard of emergency care moving into the future.展开更多

Taking Shenzhen as an example, multi- source data such as on-line taxi license plate data, plate identification data and taxi （including on-line taxis） operation data are combined with the results of the stated preference （SP） survey on taxi operating characteristics to assess the overall operation characteristics of on-line taxis. The results show that the current on-line taxis in Shenzhen can be divided into three categories, that is, full-time on-line taxis, non- active on-line taxis and part-time on-line taxis, accounting for 4%, 55%, and 41%, respectively, of the total quantity. In terms of the characteristics of space-time operations, full-time on-line taxis have similar operating characteristics as those of traditional taxis; the operation of non-active on-line taxis and part-time on-line taxis coincides with commuting requirements during morning and evening peak hours. However, part-time on-line taxis operate for a much longer time period at night. Due to the convenient hailing and favorable price, on-line taxis have a significant impact on trip modes of citizens; and the substitution eflbct of on-line taxis on traditional buses and cruising taxis is obvious. It is beneficial for helping the government departments to objectively understand the development law of the on-line taxi industry and providing decision reference for the formulation of relevant management policies during the critical development stage of on-line taxi industry.展开更多

It was demonstrated that those two kinds of travelers have distinct behavior on park and ride （P＆R）, due to their different travel demand and behavior attributes. In this paper focusing on the travelers returning in several days, the travel attributes and requirements for P＆R were analyzed with stated preference survey. A P＆R choice behavior disaggregated logit model was established and calibrated based on random utility theory. The model concludes three variables, which were travel time, parking fee and comprehensive attractiveness index for suburban satellite towns comparing to urban district. The results revealed that for travelers returning in several days the primary key point is increasing the attractiveness of suburban satellite towns.展开更多
