| Research Abstract |
Pedestrian traffic flow is studied by observation, collection and analyzes of data, and development of simulation considering pedestrians.
In 1996FY,pedestrian flow at stairway was observed and analyzed. Stairways inside railway stations are chosen for the observation. Analyzes highlight that traffic capacity is newly introduced and there is an analogy between pedestrian and vehicular traffic flow.
In 1997FY,pedestrian flow at level roadways is observed. Environments which affect pedestrian flow, such as physical geometry and surface conditions of sidewalks are studied through consulting technical guidelines and reference documents. Field observation are done at several sites in order to investigate the existing conditions and problem to be improved. Numbers of pedestrians are also interviewed to acquire users'needs on sidewalk design. Two types of sidewalk design are recommended in the technical guidelin : mounded-up type and flat type. Mounded-up type is superior in safety and drainage

features. Flat type is good at smoothness without vertical gaps. According to site observations and users'interviews, both types have their own advantages. Local road authorities are found to choose their design of sidewalks considering level of accompanying road, construction cost, aesthetic conditions, and future possibility of road construction.
On the matter of pavement materials, asphalt and concrete pavement have been standard. At sidewalks block pavements become acquiring popularity. It is found that pedestrians are not always favor of block pavements, if they are not well-maintained.
The study also considers rotary intersections since major part of traffic accidents occur at intersections. Some European countries reports that roundabouts operate well enough to avoid severe accidents. Extensive inquiry activities resulted that 27 rotaries exist throughout the country.
Simulation of pedestrian flow, ad-on modules for pedestrian flow are developed for a vehicular traffic simulation. It is found that observed traffic conditions are soundly simulated. Less
