Query: A Semi-Distributed Interior Point Algorithm for Optimal Coordination of
  Automated Vehicles at Intersections   In this paper, we consider the optimal coordination of automated vehicles at
intersections under fixed crossing orders. We formulate the problem using
direct optimal control and exploit the structure to construct a
semi-distributed primal-dual interior-point algorithm to solve it by
parallelizing most of the computations. Differently from standard distributed
optimization algorithms, where the optimization problem is split, in our
approach we split the linear algebra steps, such that the algorithm takes the
same steps as a fully centralized one, while still performing computations in a
distributed fashion. We analyze the communication requirements of the
algorithm, and propose an approximation scheme which can significantly reduce
the data exchange. We demonstrate the effectiveness of the algorithm in hard
but realistic scenarios, which show that the approximation leads to reductions
in communicated data of almost 99\% of the exact formulation, at the expense of
less than 1\% suboptimality.
