Presentation Abstract
 
UITP’s “2025 = PT 2x” initiative is more than a catchy slogan or dream! The presentation highlights the potential for capacity increase of a driverless metro line using the example of Lausanne m2 line which went into commercial service in 2008. Demand has been raising steadily, requiring the doubling of the capacity in a ten year span. By 2018, peak time capacity will have grown from 3 600 to 7’000 passenger/hour per direction. Different technical (including improved signaling, and rolling stock) and operational measures (optimized time tables) are being implemented with minimal operational disruption and full respect of safety imperatives.
As with any other systems, there is a learning curve with a driverless system. Given the right conditions, operators can « squeeze significant capacity increase » out of existing systems and infrastructure. Strong partnership between operator and supplier is essential for improvements on existing systems for which operational considerations are essential, technical boundary conditions are demanding and costs must be reasonable. The m2 example also shows how the potential for capacity increase of an existing line strengthens support for the construction of new infrastructure – in this case a new m3 driverless metro line - to respond to growing demand.

 

Congress & Exhibition: 

Parallel Session 15 - Keys to success in improving performance and efficiency

In many of our cities today, a major challenge for public transport is to increase capacity and quality and, in the context of spending constraints, to do so as efficiently (and as sustainably) as possible. Four fascinating stories from four very different networks will explore these issues and demonstrate the innovative ways in which they are being addressed. The extensive bus network of London has succeeded in expanding bus ridership by 60% since 2000 through growth in the network and raising quality of services, even in a time of reduced subsidies.
