"Road Type of Shared Carriageways", in which bicycles and cars are mixed on the roadway, is a form that requires special attention to the safety and smoothness of both traffic. Therefore, in this study, we focused on the behavior of a car overtaking bicycles on one-lane mixed-carriageway roads, and examined the width of lanes / shoulders and the traffic volume when the bicycle does not affect the overtaking car. We created virtual spaces with oncoming vehicles (excluding large vehicles) in the opposite lane and conducted experiments by driving simulation.
The results show that on lane width of 2.75 m roads with no shoulder, passing cars can be affected by bicycles at any of the traffic volumes set in the experiment. On the other hand, the results show that on roads with a shoulder width of 0.5 m in traffic volumes of up to 750 vehicles/hour, passing cars cannot be affected by bicycles. Furthermore, this study revealed that on roads with a lane width of 3.00 m and a shoulder width of 0.75 m, there is no effect of bicycles on passing cars at any of the traffic volumes set in the experiment.
