This study clarifies characteristics and factors of streets planning in post-war reconstruction urban plan of World War II in local cities by comparing with early streets plan before WWII. As the results of researching 28 cities' plans, a factor of increasing total length of streets plan is to improve arteries intervals in urbanized areas of early plans and a factor of widening planned streets is to up-grade the width level of early ones.
Though post-war reconstruction streets plan changed each city structure by changing place of wider arteries or adding boulevards newly, it fundamentally succeeded early plans' streets pattern and street courses which form city blocks and station squares.
