Abstract
The purpose of this document is to give a more detailed explanation of the
performance degradation as described in the paper "Optimal coordination of
variable speed limits to suppress shock waves" (by A. Hegyi, B. De Schutter,
and J. Hellendoorn,
Transportation Research Record, no.
1852, pp. 167-174, 2004). For the simulation settings in that paper the
degradation occurs for the "floor" type of rounding of the real-valued control
signal (resulting from the MPC optimization), but does not occur for "round"
and "ceil" types of rounding. In this document we show and explain that if the
discrete-valued speed limit step size is increased, the degradation occurs in
all cases, but for the floor type of rounding first.
