Dynamic Evolution Game of Travelers’ Air-to-HSR Choice under the Scenario of HSR Speed-Up

With the technological advancement, China’s high-speed rail (HSR) has achieved a higher running speed than ever before, which at the same time leads to the intensive competition between air and high-speed rail with trips within 500–1000 km, as well as to the significant changes of travelers’ air-to-HSR choice. In order to explore the dynamic adaptation of travelers’ choice of high-speed rail (HSR) and air in the case of HSR speed-up, a logit dynamics model of travelers’ choice based on evolutionary game was constructed to describe the evolution of travelers’ choice. With HSR-air travel time and the ticket price of origin-destination (OD) points of Beijing-Shanghai as the benchmark, the study set up two scenarios of HSR speed-up and compared and analyzed their payoffs in value. On the basis of mathematical simulation, the travelers’ “air-to-HSR choice” and the change of competition range under the background of HSR speed-up were both discussed. The result indicated that the HSR speed-up would attract more travelers, and its share rate would rise to 58.31% and 72.73%, respectively, with HSR running speed increasing to 400 and 600 km/h; the marginal utility of HSR speed-up is more obvious, and in the meantime, the increase of HSR running speed extends the intense HSR-air competition range to longer-distance travels. In the case of HSR speed-up, travelers’ choice changes as well. The HSR operators themselves should formulate reasonable ticket prices and improve their management. At the same time, the air operators should adjust their operation plan in time.

Wave Propagation Speed

With full development of 350km/h high-speed rail network in China, further research in the key technology of 380km/h or higher super-speed rail system has become crucial. Applying the simulation of pantograph-catenary interaction based on infinite element method, this paper simulated the dynamic performance of pantograph-catenary system for high-tension overhead contact system at over 350km/h. The research findings showed that wave propagation speed can still serve as a brief computing method for the running speed within the range of 350-400km/h. When the running speed reaches 80% of the wave propagation speed or higher, the current-carrying quality of double-pantograph-catenaries system might not satisfy the standard of EN 50367 all the time.

Abstract The modern society’s continuous increasing mobility requirements have encouraged new transportation technological platforms. The so called Hyperloop concept, also described as the fifth mode of transport (rather than road, rail, water and air) for both passenger and/or freight) is supported on the idea of a pod like vehicle, running in a near vacuum environment (inside tubes) at near sonic speeds, higher than current air transport ones. This technological approach has played a prominent role in the modern transport scenario, with a potential to offer high service levels, associated with high speed, reliability and weather operational flexibility, as well as reduced environmental footprint and costs. This groundbreaking technological concept, albeit revolutionary, can not be seen as a novelty, with previous precursors being proposed in the last century. However, the concept has been reintroduced in 2012 with updated technologies, in an open sourced format, by the acknowledged entrepreneur Elon Musk, to instigate further improvement/development among interested companies worldwide, focused on its exploration on a commercial scale in the near future. The Hyperloop concept is envisioned to compete with both the High Speed Rail (HSR) and Maglev services, in the 160–640 km (100–400 mi) range, as well as air transport, for up to 1,000 km (625 mi) range, with alleged both environmental and cost advantages over their competitors. However, despite the technology’s high performance potential, given its multidisciplinary feature (sonic/high speed, near vacuum, linear motor propulsion, electric power storage, pod environment maintenance/cooling, air quality control, transport capacity, among others) and its inherent current low maturity from both the engineering, operational and cost perspectives, there are several major technological, regulatory, planning, financial and environmental challenges to be addressed, prior to reach the commercial service status. In this context, it is currently required a huge research effort to figure out technological barriers, followed by prototype tests, to set up the safety and operational requirements. Work is current under way, with a huge research effort (from both the academy and the industry) focused on basic technological concepts, as well as some prototype tests (currently unmanned) driven to test the specific main technological approaches in a real world condition. Given its revolutionary feature, Hyperloop technology is seemed as both ambitious and controversial by the general public and transport experts, with some optimistic bets in its medium term revolutionary role in the passenger transport market, focused on some niche segments currently serviced by the rail mode, as well as other skeptical bets in its restricted role to the freight market, given some inherent safety issues. This work is supposed to present a review (supported on the current available technical literature) of the groundbreaking Hyperloop technology concept and its potential to fill some specific rail niche markets, in both passenger and/or freight segments, with an assessment of the main technology’s hurdles/bottlenecks status and their perspectives, from a technological, environmental and cost focus, followed by a snapshot of some potential Hyperloop project candidates.

Speed Up

A relatively new entry, in the field of microscopy, is the Scanning X-Ray Fluorescence Microscope (SXRFM). Using this type of instrument (e.g. Kevex Omicron X-ray Microprobe), one can obtain multiple elemental x-ray images, from the analysis of materials which show heterogeneity. The SXRFM obtains images by collimating an x-ray beam (e.g. 100 μm diameter), and then scanning the sample with a high-speed x-y stage. To speed up the image acquisition, data is acquired "on-the-fly" by slew-scanning the stage along the x-axis, like a TV or SEM scan. To reduce the overhead from "fly-back," the images can be acquired by bi-directional scanning of the x-axis. This results in very little overhead with the re-positioning of the sample stage. The image acquisition rate is dominated by the x-ray acquisition rate. Therefore, the total x-ray image acquisition rate, using the SXRFM, is very comparable to an SEM. Although the x-ray spatial resolution of the SXRFM is worse than an SEM (say 100 vs. 2 μm), there are several other advantages.
