Anticipating Automated Vehicle Presence and the Effects on Interactions with Conventional Traffic and Infrastructure

Abstract

Expectations are that automated and connected mobility will increase road safety and traffic efficiency. However, due to possible shortcomings of new technologies , road users may be confronted with disturbances and potential safety risks. The mitigation of such risks will bring necessary changes to road infrastructure, vehicles and road-users' behavior. In a traffic environment that was built to fit the human perception, preemptive simulation of parametrized scenarios can provide guidelines for what changes and difficulties are to be expected. Utilizing SUMO in varied scenarios, this paper outlines the creation of virtual models that correspond to interaction hot spots on the Austrian road network -from digitizing the infrastructure, to calibrating a simulation scenario with congruent traffic measurements -while it concludes with the evaluation of scenario simulation results. The approach is demonstrated for a selected motorway ramp scenario, varying rates of automated vehicles and different infrastructure layouts. Performance indicators like vehicle speed distributions and traffic disruptions are defined and analyzed to investigate how adaptations can mitigate risks, influence traffic flow and hence support progressing vehicle automation.

Extending the Intelligent Driver Model in SUMO and Verifying the Drive Off Trajectories with Aerial Measurements

“…They point out that future work would need to analyze the impact of human drivers in the scenario to better quantify the improvements. Richter et al (2019) actually study the effect of mixed traffic (autonomous vehicles and human drivers) on a highway. They use the Krauss model (Krauss et al 1997) and define smaller time headways, reaction times and sigma values (driver imperfection) for autonomous vehicles.…”

Conflicts of Automated Driving With Conventional Traffic Infrastructure

“…In summary, it can be said that with transport micro-simulations -such as the current example -it can efficiently and on a small budget find opportunities for changes in the infrastructure with which it can be accelerated the spread of self-driving vehicles. [28] The structure of paper: Chapter 1 is the introduction. Chapter 2 presents the conflicts of automated driving problems.…”
