Research result：
Taiwan is now experiencing a higher number and ownership of motorcycles, and it has become the primary traffic pattern for people in Taiwan. In the meantime, the motorcycle accident also accounts for extremely high percentages. Aiming at the accident type frequently seen under the Mixed Traffic Flow Scenario, this research proposed the improvement method for the design of transportation construction equipment while establishing the design sample. In 2016, the accident diagnostic analysis was conducted for accidents caused by side impact at the junction in order to submit the model improvement examples.
Aiming at the left-turn side impact accident frequently seen at the junction, the solutions and conditions for setting up motorcycle left-turn lane are planned for the road junction subjecting to sufficient road width, frequent motorcycle impact and massive motorcycle left-turn and where the left-turn waiting zone is not allowed.
Promotion of result：
- In the future, suitable road junctions will be selected for studying the improvement trail execution plan in order to verify the improvement at the road junction.
- The verification result will be included in the respective Frequent Accident Section Improvement Plan in the Taiwan Area in order that it will be promoted and applied in the analysis and joint improvement inspection at the accident location.
- Conduct the Education & Training Seminar for reporting the applicable improvement conditions and the transportation project package design to the respective level of the competent authority, transportation construction consultant and the units involved.
