Nowadays, various signalized intersections with bicycle lanes designs are available for implementation. However, no safety comparisons have been made between these various designs. Therefore, it is necessary to compare the various designs available. In this study, intersection designs from Western countries are investigated to determine the safety measures available. Then the safety and comfort are compared with left-hooks being focused. Five patterns were selected including (1) Mixed traffic with left-turning motorist; (2) Left-turn in the intersection for motorist; (3) Bicycle signal; (4) Advanced stop lines for bicycles; and (5) Bicycle box. The five intersection patterns were prepared at an experiment site, and human subjects consisting bicyclist and motorist were traveled on the specified route freely. Questionnaire surveys and video observations were used for data analyses. The results show that (1) Mixed traffic with left-turning motorist is the safest and (3) Bicycle signal is the most comfortable intersection design.
