We investigate the effects of mobile-sourced ridesharing via platforms like Uber, Lyft, and Didi Chuxing on the use of public transit systems. Our study uses trip-level data about Uber usage in New York City, turnstile data about subway usage, and trip-level data about taxicab and shared bike usage. We find that on the surface, ridesharing and subway usage are positively correlated. Exploiting ...

In this paper, we investigate how to increase the capacity of GSM (Global System for Mobile communications) radio interfaces in subway tunnel environments by means of antenna arrays and Space–Time (ST) receivers. We address the modeling, both theoretically and experimentally, of the multiple-antenna wireless channels encountered in subway tunnels. We demonstrate that propagation is conveniently...

I nformation that facilitates efficient movement through transit facilities provided by station architecture or by signs is a crucial design factor affecting such issues as passenger security, convenience, and the desire to use transit. The information aspect of station design can also have a major impact on capital and operating costs, The information needs of passengers in transit facilities,...

Energy management in existing building services installations is an essential focus of contemporary facilities management. The subway company that is one of the major utilities services in Hong Kong Special Administrative Region (HKSAR) has considered better energy management schemes in its subway stations to reduce the running cost. In the past few years, in order to achieve energy saving in t...

On 10 May 2016, Guangdong Province, China, suffered a heavy rainstorm. This rainstorm flooded the whole city of Guangzhou. More than 100,000 people were affected by the flooding, in which eight people lost their lives. Subway stations, cars, and buses were submerged. In order to analyse the influential factors of this flooding, topographical characteristics were mapped using Digital Elevation M...

is paper tries to build on traditional value capturemeasures, to estimate the potential of some of thesemechanisms for the Lisbon subway by examining their ability to mitigate the system’s operation and development costs. e study focus is on the municipality of Lisbon where this system mainly operates. is research uses spatial hedonic pricing models of the real estate of the region, calibrat...

Some incidents in urban railway systems affect the function of the subway’s company adversely and they could disorder the services. These events may inflict irreparable damage to passengers, employees and equipment. By recognizing the hazards existing in this type of transportation system and evaluating and prioritizing risks, we can perform appropriate actions to reduce the probability and sev...

the effect of underground cavities in site seismic response was studied over the subway tunnels that are under construction in the city of karaj, using ambient noise measurements as well as numerical modeling. the idea for this research comes from the observation of differences in experimental site transfer function, calculated on more than 100 locations of the city, for the areas near the unde...
