Transports Publics de la région Lausannoise, Lausanne, Switzerland
Marc Badoux is deputy Director of tl, the public transportation company of Lausanne, Switzerland. His team is in charge of conducting infrastructure and equipment projects for renewing, improving and extending tl’s transport network. Current projects include a new tram line, a new metro line and new high-peformance bus lines. Prior to joining tl, Marc worked in engineering consulting firms in the United States and in Switzerland and as an Assistant Professor at the Swiss Federal Institute of Technology (EPFL). He graduated from ETH Zurich and holds a PhD from the University of Texas and an Executive MBA from IMD.
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.
