β¦ Synopsis
Highway automation entails the application of control, sensing and communication technologies to road vehicles, with the objective of improving highway performance. It has been envisioned that automation could increase highway capacity by a factor of three. The purpose of this paper is to develop a methodology for predicting highway capacity and comparing alternative automation concepts. It extends earlier research on optimal lane assignment on an automated highway to dynamic networks. A path-based linear program is formulated and solved through a column generation method. The algorithm has been applied to networks with as many as 20 on and o ramps, 80 segments, 4 lanes and 12 time periods.

In a fading channel without ISI, the approximate theoretical BER for a diversity reception system where multilevel coding is applied has been determined. The result obtained from the approximate theoretical BER method matches the simulation result, and thus this method can be used as an alternative
