ABSTRACT: 
The road is greatly changed by the constant economic growth for a long time the traffic situation such as the vehicles of increase and 
large, the performance enlargement of vehicles, the high speed, etc., due to increasing economic scale. Therefore, secure smooth 
traffic of vehicles and driving road safety that was appeared at the age of the request. The road is necessary to transfer goods and 
people the essential public traffic, the road network is connected with increasing the national land of function both all over the 
country of road network and the local road network. Each road was in charge of the national land development and the improvement 
of living conditions in cooperation with each other. Especially, increase a number of vehicles, according as road network by the 
significant of traffic that is increased in movement, convenience and economic, economic and social development provided people 
of the improvement of living conditions. A study about an optimal route selection model is researched over late 1980s by 
development of computer and GIS, and consisted including research about optimal route that use digital terrain model in domestic 
such as the earth volume calculations, mass curve output and automation system construction. 
1. MANUSCRIPT 
The road is greatly changed by the constant economic growth 
for a long time the traffic situation such as the vehicles of 
increase and large, the performance enlargement of vehicles, 
the high speed, etc., due to increasing economic scale. 
Therefore, secure smooth traffic of vehicles and driving road 
safety that was appeared at the age of the request. 
The road is necessary to transfer goods and people the essential 
public traffic, the road network is connected with increasing the 
national land of function both all over the country of road 
network and the local road network. Each road was in charge 
of the national land development and the improvement of living 
conditions in cooperation with each other. Especially, increase a 
number of vehicles, according as road network by the 
significant of traffic that is increased in movement, convenience 
and economic, economic and social development provided 
people of the improvement of living conditions. 
A study about an optimal route selection model is researched 
over late 1980s by development of computer and GIS, and 
consisted including research about optimal route that use digital 
terrain model in domestic such as the earth volume calculations, 
mass curve output and automation system construction. 
Lately, the study about the driving simulation on the road and 
virtual reality using VGIS(Virtual Geographic Information 
System) is researched. | 
However, the optimal route selection uses topography 
information that is not used much in businesses because of 
several problems that must solve them such as complexity of 
data, popular enmity problem, and noise pollution. 
Usually, if the route selection reviewed sufficiently data 
examination at the first time, it happened the additional expense 
due to the route alteration by data examination of insufficiency 
  
According to Busan local capital intendance, in 2000, 
suspension of works by design indifferent, increased 
construction cost arrived to 570 situations. 
Those significant reasons of construction delay are occurred by 
recasting expense that was not considered of popular enmity 
problem by the design change such as estate fluctuations and 
environment effect. 
Especially, the downtown area has much bigger problems that 
were not considered of environment effect and city fine view. 
Therefore, if it was considered of environment effect and city 
fine view after completion, it could be decreasing unnecessary 
construction period and expense by the design change. 
This study is when the alternate road selection considered 
surrounding facilities, development plan, and according to 
estimate amount of traffic. The additional possibility of view 
analysis and environment effects of analysis elements will study 
through 3D simulation method. 
2. ROUTE LOCATION DESIGN STANDARDS 
2.1 Geometric structure standards 
This study is judged to achieve the movement of the downtown 
area by the main function as built road to plan traffic situation 
improvement and regionally balanced development of the main 
road. Road cross section components are divided on the road, 
the separator and the shoulder. It is examined by composing 
correct crossing width to design speed 80km/h by freshness 
worthy undertaking urban areas week to 'Structure and Facility 
standards of the road regulations'. 
Especially, the road is adapted to take into consideration the 
design surrounding situation which has topography situation 
upper restriction. Owing to design speed, the geometric 
structure standards is the same with table 1, such as the
