Timetable design is crucial to the reliability of a metro service. In terms of the delays caused by passengers’ boarding and alighting behaviors during rush hours, the planned timetable for a metro line with high-frequency service tends to be difficult to implement. General oversaturation events, rather than accidents or track damage, still have a significant impact on metro systems, so that tr...

Metro Ethernet has been widely adopted lately. One of its goals is to provide clients with VPN services, and in this context, loadbalancing and protection have become important issues. This paper presents an original formulation of these problems in Metro Ethernet, and introduces an algorithm for load balancing which provides good numerical results.

As current sustained traffic growth is expected to strain capacity of today’s metro network, novel content distribution architectures where contents are placed closer to the users are being investigated. In that regard, telecom operators can deploy datacenters (DCs) in metro areas, thus reducing the impact of the traffic going from users to DCs. However, effective solutions to distribute conten...

As informal workers struggle to survive the current crisis, there is reason believe that more strain would also be exerted on already fragile sector in post-crisis era. The implications of COVID-19 outbreak for economy will continue. Faced with a long global likely shrink demand goods and services. primary goal this paper study consumer behavior during pandemic, investigate government-implement...

This document describes the applicability of the MPLS Transport Profile (MPLS-TP) with use case studies and network design considerations. The use cases include Metro Ethernet access and aggregation transport, mobile backhaul, and packet optical transport.

To study the impact of information dissemination on public's risk perception in metro emergencies, we carried out an empirical study among Shanghai Metro passengers. Though an investigation of passengers’ response to the frequency, type and channel of information dissemination, we developed a Logit model measuring public response for future manipulation.

The development of metro infrastructure projects (MIP) has been playing an important role in the economic growth in China through improving urban transportation condition. The economic benefits from MIP in China have been well appreciated. However, concerns on the utility efficiency and the impacts of MIP on social and environmental aspects have been increasingly raised. It is anticipated that ...
