Introduction
In the introduction will be stated: the purpose of our assignment and the structure of the report.
Focus, Objectives and Approach
Literature study
In this chapter the state of the art will be identified and summarized. Very specifically mention the research gap that was identified
Algorithms and plans for intersections with autonomous vehicles
Intersection algorithms
Sensors in automated vehicles
Current communication systems
Algorithm and Simulation
Algorithm
Here the choices of the algorithm will be stated. Like the requirements, preferences and constraints and how this was built toward the final algorithm and design of the intersection.
Simulation
Here the implementation of the algorithm is stated and the choices and methods for the simulation are explained. Like the choice to generate the traffic by a Poisson distribution and what the things are that we designed but did not include in the simulation.
Communication protocol
In order to make the algorithm work, a communication protocol has to be implemented in the intersection system. Following the literature research on current communication systems that exist between intersections and busses and ambulances, the KAR system was identified. This is a system that is already present in current intersections. It is based on a short distance radio. [1]
When implementing it into the situation with autonomous cars, every autonomous car will be able to send information on their position, provided by their navigation system, to the intersection. The intersection is then able to know where every autonomous car is on the intersection. In reverse, the intersection is able to send information to the autonomous cars as well. In that way, the cars can anticipate on the time they will have to wait at the intersection and adjust their speed accordingly so a minimum amount of breaking and quick speed reduction is required, which increases the comfort for the autonomous car users. [1]
It is also possible to implement a reservation system into the KAR system as it is already used for buses. The bus can now send their route information to the intersection so that the intersection knows how high the priority for that bus is. The same system could be used for autonomous cars. However, the question is how fair this is toward human drivers who will not be able to send their level of priority to the intersection. Therefore, it might not be user-friendly to implement this part of the KAR system into the intersections. [2]
