◼ In order to expand a safe and reliable walking space early and inexpensively, it is possible to make an effort to secure a space for pedestrians

• first. The expansion of the walking space and the

reduction of the road width are realistic methods, but their spread is insufficient. ➢ The specific approaches are; 1)Expand in conjunction with areal speed regulation (zone 30) 2) Assure a sufficient agreement with local community 3) Raise a proactive awareness of traffic safety 4) Encourage the local authorities and communities to develop the pedestrian priority efforts widely

Thank you for your kind attention.
