Abstract

<p>In this paper, a method is proposed for improving level of service in congested urban railways with special travel demand characteristics by means of triple-track line operation. Where the future travel demand forecasts show sluggish growth, there is little incentives for railway investments like quadruple-track extension to alleviate current railway congestion problems. In such a situation, triple-track line operation can be the best alternative due to its moderate investment cost and ease in land acquisition for just an additional single track along the existing tracks. The simulation investigation showed that triple track line operation can increase railway capacity by 26% and shorten travel time by 38% in peak direction during morning peak hours. These results are encouraging and are potentially useful for overcoming current railway problems in Tokyo and in similar urban situations elsewhere.</p>
