The "Electronic Eyes" (Dynamic Traffic Information Board), which were in
operation on Yan'an Road Viaduct, will soon be installed in North-South Viaduct
and inner ring road. Vehicles can choose their lane in advance according to the
information on the board so as to increase their efficiency. The traffic
information collection system will also be expanded at crossroads. "Electronic
guards" will be installed at 150 busy road sections by the end of the year so as
to provide policy guidance for the renovation of road network. it is reported
from Shanghai Urban Infrastructure Engineerng Administration on June 14th that
various kinds of information technologies have been applied in Shanghai to solve
the problem of traffic jam in Shanghai.
In the recent years, a large number of road facilities have been built in
Shanghai. However, with the increase of motorized vehicles and the urban space
becoming more and more tense, building roads to improve traffic situation is not
realistic and not scientific. By referring to the successful experience of
Japan, USA and other developed countries, Shanghai plans to improve the
efficiency of road traffic by means of modern traffic information
administration.
The launching of traffic information collecting systm at crossroads will
provide scientific basis for improving the road networ. By means of expanding
the roads and extending the roads, we can actually build smooth road networks.
However, it is a big issue to decide which way needs the renovation and the
extention. On Xi Zang Road Middle, Yan'an Road East, Xu Jia Hui Road and Chong
Qing Road South and other busy roads, experts of urban infrastructure get the
data collected by electronic guards buried underground and are thus able to
decide on which roads need renovation. Small schemes ay improve the efficiency
of the whole network.
Improving the information collection system in downtown area of the city
makes it possible for vehicles to now the traffic situation in advance so as to
avoid traffic jam. Experts of urban infrastructure bury a group of round testing
cables every 400 meters on the lanes of viaduct so as to get such datas as
traffic flow, road occupancy, vehicle type and vehicle speed. According to the
test, after installing the information guiding system on Yan'an Road Viaduct,
the efficiency of vehicles increased by 20%. It is reported that there will be
more than 20 traffic information boards on the two ways of North-south Viaduct
(inside the inner ring road), two ways of inner ring road, and the east to west
side of Yan'an road Viaduct. Viaduct supervision and control center will also be
upgraded.
By means of these information technologies, all the origial infrastructure
facilities have been used to their full extent. In Huang Pu District, vehicles
may have to drive for several rounds in order to find a parking space. After the
installation of parking information board, they can find parking lots easily,
thus, reducing the traffic pressure on roads. By means of the latest "Traffic
Emulating Software", if urban infrastructure experts want to renovate a certain
road section, they can type in certain datas, and the computer and emulate the
traffic situation after the renovation of the roads, which helps the experts
greately.
