Abstract
In this study, we propose an evaluation method for an Advanced Rider Assistance System (ARAS) for two-wheeled vehicles, combining riding simulator experiments and computer simulations in terms of cost-benefit analysis. This evaluation method focuses on the collision warning system at intersections using an ARAS for two-wheeled vehicles. The study was carried out experiments with 30 test subjects who have two-wheeled vehicle licenses and are not novice riders. To quantify the accident-reduction effect, a Monte-Carlo simulation based on a time-series reliability model was used. Based on the collision probability results derived from the Monte-Carlo Simulation, the overall error probability as a human-machine system was calculated based on an integrated error model. In addition, cost-benefit analysis was conducted to quantify the social benefits and costs of introducing the ARAS to the market. As a result, we confirmed that the system can be beneficial after 4 years when introduced into the market.
Highlights
Advanced Driver Assistance Systems (ADAS) for fourwheeled vehicle safety such as Forward Vehicle Collision Warning System (FVCWS) and Lane Departure Warning System (LDWS) are already in practical use
We investigated riding behaviors in terms of parameters that are related to the risk of traffic accidents including Reaction Time (RT), Average Deceleration (AD)
AD indicates the average value of deceleration starting from responsive brake operation until the vehicle stops completely and it is a critical parameter when braking operation in risky situations
Summary
Advanced Driver Assistance Systems (ADAS) for fourwheeled vehicle safety such as Forward Vehicle Collision Warning System (FVCWS) and Lane Departure Warning System (LDWS) are already in practical use. ADAS using Information and Communication Technology (ICT) such as Vehicle-to-Everything communication (V2X) are currently being developed [1,2,3]. There are some studies that evaluated the accident-reduction effect of such systems [14], there are few evaluation methods that consider the social benefits. Cost-benefit analysis is typically used in evaluating the public utility of certain services or systems as a predictor which evaluates whether a new service or system will become beneficial to society, or not
