Abstract

With the improvement of living conditions and booming tourism in Tibet, more and more people choose Tibet as a tourism destination. More emergency events may happen when lots of people swarm into Tibet. This paper focuses on the accessibility of road network near Jokhang Temple in Lhasa at a peak tourist season with different events coupling. Some data about path lane, path width and trips of road has been collected and accessibility of road near Jokhang Temple has been computed with two disparate events. The result shows different emergencies coupling may cause different consequences to road network. So highway management department can set up various strategies to speed up traffic flow based on the degree of events coupling and make relevant measurements.
