How to get a smoother ride on BART

How to get a smoother ride on BART

Outline

The transit system connects San Francisco to East Bay communities

Numerous optimization problems arise in the area of advanced automatic train control

Modern radio-based train control systems provide a new domain for applying optimization techniques

Description of the Control Simulator

A train experiences interference during acceleration

Enhanced train control objectives for a more reliable system

Our enhanced control objective is to smooth interference during acceleration

We apply interior-point algorithms to determine an acceleration trajectory

We use O3D to solve the quadratic program in the enhanced controller

Simulation Conditions
