This paper presents a traveler guidance system that offers 3D street information such as road types, signal light systems, street trees, buildings, etc. We consider 5x4 road system of Gangnam(in Seoul, Korea) as a test area and reflect the traveler's car-driving situation. A web server is constructed to serve traveler's driving path by switching 3D animation scenes automatically. To do batch processing of geometric data for the 3D graphical streets construction, we have extracted major street information from present GIS database and created new GIS file formats (SMF files), which contain data sessions for links, nodes, and facilities. With these files, we can render 3D navigation scenes. A number of vector calculations were performed for the geometrical consistence and texture-mapping method was used for the realistic scene generation. Finally, we have verified the effectiveness of the service by operating a test scenario. We have checked whether traveler's 2D path and 3D navigation are exactly reported after setting specific departure and destination. This system offers us well awareness of streets and takes useful role of traveler guidance.

The purpose of this study is to examine the standard scale of measuring a block of Kyongju(慶州), the Capital of the Silla Dynasty(B.C.57${\sim}$A.D.935). Through the study, it is clarified that 1). the block of Kyongju city is planned and divided by using the eight-Zhou-foot(周尺) as a standard scale, which is equivalent to the length of one-bo(보(步); 2). the distance between the center of the streets is around 100 bo and the width of the block is around 90 bo; 3). the distance between the streets is very near to the distance 167.054m of Jing-tian-zhi(井田制), which supports the use of Zhou-foot as a standard scale. As a result, it can be maintained that the city planning of Kyongju is related to that the Jing-tian-zhi of the Zhou Dynasty and the standard scale of measuring a block of Kyongju us executed by using the eight-Zhou-foot standard scale.

This study analyzes the characteristics of special configuration for wayfinding in general hospitals. To that end, the study categorizes four different hospitals, according to the type of their wayfinding systems. It aims at utilizing the result of the analysis for wayfinding system in general hospitals by applying three elements of analysis methods', perpetual access, depth, and intelligibility. The study result shows as follows: First, there is no difference in special hierarchy when hospitals are analyzed and divided by halls and streets. It means that outpatient departments are located by spatial function and characteristics rather than form of spatial configuration. Second, we found that fewer direction changes are conducive to easier circulation in terms of wayfinding, when we analyzed spatial depth from the main entrances to the outpatient departments. Third, regarding intelligibility, intelligibility of Chungang University Hospital ranked highest. Kunkook University Hospital, Dongkook University Hospital and Seoul National University Hospital ranked 2nd, 3rd, and 4th respectively. It means that difficulty level of wayfinding is not decided by the characteristics of special configuration such as hospital hall and hospital streets but depends on location planning. The difficulty level of wayfinding mainly relies on location planning.

The purpose of this research is to suggest the planting methods and the reasonable target levels of IGS for promoting green streetscape in Seoul. Using the three dimensional computer simulations, various greening methods were applied to evaluate effectiveness of promoting green streetscape. The results of this study suggest that promoting tree planting on car lane is more effective than on pedestrian side walks. In wide streets, the height of tree has positive effects on promoting green streetscape. In both car lane and pedestrian side walks, the greening effects of tree planting both in zig-zag pattern and in parallel pattern were similarly most high. The width of strip in side strip planting has positive effect on promoting green streetscape. Promoting stratified planting is very effective. Promoting greening wall on pedestrian side walks is more effective than on car lane. Combined the results of IGS survey with the public officials and complex simulations, suggest that the optimal levels of IGS is ranging from 12.0% in alleys to 54.0% in car lanes among arterial roads.

In this paper, Coordinated Semi-Actuated Signal Control algorithm was developed and evaluated. According to the analysis of simulation, the coordinated semi-actuated signal control led to reduced vehicle delay as the difference of traffic volume between major and minor streets was getting bigger. But when there was relatively high traffic volume, or the equivalent amount of traffic volume on major and minor streets, optimized pre-timed signal control was verified to lower delay times compared to coordinated semi-actuated signal control; however, it might increase pedestrian delay. Therefore, the coordinated semi-actuated signal control should be implemented at intersections where traffic volume is relatively low.
