Micro-mobility rider models for stochastic traffic safety simulations

The safeguarding of autonomous vehicles with regard to safety is an issue that automobile companies are currently having to deal with. Testing autonomous driving functions in real traffic with performance monitoring and trained operators behind the wheels, so-called field operational tests (FOT), are the most obvious approach, but will no longer be feasible with more complex active safety systems, as accidents and particularly fatal accidents are very rare, besides the danger and ethical aspects of testing such situations. To ensure that autonomous vehicles are at least as safe as human drivers, new strategies are needed to prove safety and reliability. One reasonable approach are Monte Carlo simulations, which, due to the arbitrarily high number of test runs, combinatorically cover a large number of possible scenarios. From this, as in medicine, a randomized controlled trial can be designed, by which a reference is compared with a treatment in order to derive a "before and after impact", including possible side effects. To this end, it is essential to simulate traffic scenarios with the necessary degree of detail, to model potential road users with realistic behavior and to assign meaningful probability distributions to variable parameters, which are "drawn" anew in each test run. These simulated test runs can then be understood as virtual FOT. This work aims to identify the relevant parameters and their causal relationships for micro-mobility riders focusing on the domain safety. Furthermore, a strategy is developed to obtain these parameters and derive stochastic models to describe subpopulations. Especially parameters in critical situations and human error are crucial and need to be modeled adequately, but also pose huge challenges due to limited data and ethical constraints. A micro-mobility model for traffic simulations, including probability distributions for significant parameters and human failure will be developed and implemented. Finally, a use case is defined and an effectiveness analysis of a traffic treatment (eg. V2X) is performed demonstrated using e-scooters.
