Called the urban arteries, the traffic is significantly affected by its congestion. One of the solutions to this is overpass, whose construction is forced to be amidst heavy traffic and thus extending the construction period. To deal with these situations, a crossing-over structure method have been developed in a range of sectors with a result that these few years have seen as many as 43 new work methods.
In contrast, another solution to the excessive concentration of urban traffic is the use of the underground. The underground space in major cities, however, is packed with a tangled web of subway systems, roads, and other lifelines, the situation which forces the use of underground at greater depths.
The paper examines these current situations and offers analysis and suggestions for the future direction in the technological development and issues to deal with.
