〖作品简介〗
A method of intersection channelization by CAD is developed in this paper
. Many factors have affections on the final way of intersection channelization
, includeing the shape of intersection, the status of traffic flow, the method
of traffic regulaton and the existing buildings around the intersection
, and also the planning of urban development .The authors start from
the basic data of the intersection listed above, then group the
data into several classes and finally give the regulation of intersection
channelization and propose the method which helps designers to expediently
channelize the intersection traffic on computer.
The intersection is the bottleneck of the road net. 60% of the accidents
and most of the congestions happen at the intersection or neighborhood
. Therefore planning and design of the Intersection is very important to
the road expedite and the traffic safety. The intersection channelization
aims to solve all kinds of problems in related to the intersection, and
to take proper methods to improve the capability of the intersection.
Through channelization the traffic capacity can be increased and the efficiency
can be improved. After road is channelized, the interferes between persons
and vehicles will reduce, then the traffic capacity will be increased
and the road will become more expedite. Since the mix traffic is the most
important character in many cities of china, and vehicles and non-vehicles
and also passersbys affect each other, congestions often occur when they
are passing which will be relieved after the road channelization.
And intersection channelization can also reduce traffic accidents, for the
subjective and external causes, when vehicles, non-vehicles and also passersbys
are passing together on the narrow roads, the liberty of the traffic participators
is rather high, quite a big part of the traffic participators are lack of
safety consciousness, and of all these lead to the traffic chaos, and traffic
accidents easily happen. Through channelization, the flow is separated,
vehicles and passers travel on their own lanes. So the peccancies and traffic
accidents will be hugely reduced.

Intersection channelization can also beautify the environment of cities
, the air quality is one of the important indexes of the environment benefit
analyse in the designing of the intersection channelization. According
to some concerned research, traffic delay has large effect on the air quality
of the intersection and around it. Therefore improving the traffic organization
, reducing queuing delay can obviously prevent the pollution caused by traffic
.
The authors develpe a CAD method of intersection channelization ,in order
to improving the designer's efficiency. They also apply it in practice and
gain well effect.
