This document is the user manual for LANE-OPT. LANE-OPT is a linear program based software package that optimally assigns traffic to lanes on an automated highway. The program is based on a workload model, such that each lane/segment has a fixed capacity than can be allocated among: (1) straight traffic, (2) lane changes into the lane, (3) lane changes out from the lane, and (4) lane changes that pass through the lane. Each of these four movements produces a user-specified workload. The computer program models the highway as a multi-commodity flow network, where commodities represent destinations. The linear program maximizes total network flow, accounting for lane/segment capacities and a fixed origin/destination pattern, which is expressed on a proportion basis.
