Traffic Accidents in Japan

Historical Background g In 1970, traffic accident deaths reached their peak. y were p permitted to run on sidewalks. Bicycles Confusion arose about how and where to ride a bicycle. Rapid increase of bicycle usage after Great East Japan Earthquake on 2011.3.11. g of super-aging p g g society. y Progress A sharp increase in bicycle-pedestrian traffic accidents in recent years. 4

Comprehensive p Measures Toward Better Bicycle Traffic Order (National Police Agency, 2011)
Basic principles p p Bicycle is a vehicle Bicycle should run on the left side of the roadway Exception: E ti children hild under d 13, 13 and d seniors i over 70
Promotion of traffic safety education Enforcement of bicycle traffic laws Provision P i i off bicycle bi l traffic t ffi space 7
Five Basic Safety Rules 1. Bicycle to run on roadway
2. Run left side of roadway
4. Observe safety rules
3. Priorityy to pedestrians
5. Bike helmets for children

Guidelines for Safe and Comfortable Bicycle y Usage g Environment (Ministry of Land, Infrastructure and Transport, 2012)
Planning of bicycle route network Design of bicycle traffic space Enforcement of bicycle traffic laws Comprehensive measures for bicycle use 9
Bicycle Traffic Spaces ① Bicycle y road
② Exclusive bike lane ③ Shared bike/auto zone

Problems of Existing Intersections Bicycle crossing and traffic signal
Bicycle crossing design leading to car/bike conflict 11
Utsunomiya y Cityy A regional capital with half a million population Flat terrain suitable for bicycles High bicycle usage

Conclusion and Future Work In this paper, paper we tried to solve: How to share bicycle and auto space on a narrow street Ensure straight path for bicycle in intersection
In In the future, we will pursue: Design for irregular and complex intersection Reallocation of road space among various modes Coordination between bicycle and public transport Achieving a comprehensive urban transport network where bicycles play an important role
