SPEED AS A CONSEQUENCE OF TECHNOLOGICAL DEVELOPMENT TECHNOLOGY IS CONTINUOUSLY PROVIDING SOLUTIONS- MECHANICS, MATERIALS, ENGINES…- FOR INCREASING SPEED 9 Workshop on High Speed. Warsaw, November 2011

A passenger transport mode is a particular technology applied to a function, the function of transporting people in different kind of ways (water, air, roads) 10 Workshop on High Speed. Warsaw, November 2011 SPEED AS A CONSEQUENCE OF TECHNOLOGICAL DEVELOPMENT

In some cases, the maximum commercial speed not always is following an increasing trend 11 Workshop on High Speed. Warsaw, November 2011 OPTIMUM SPEED IN DIFFERENT TRANSPORT MODES

12 Workshop on High Speed. Warsaw, November 2011 THE RAILWAYS SYSTEM SINGULARITY

OPERATIONAL LIMITS TO THE MAXIMUM SPEED WHAT ARE THE MAIN CONSTRAINS TO THE OPERATIONAL SPEED INCREASE? Some phenomena and parameters to take into account:  Safety ___________social perception, historical evolution.  Economy ________Energy consumption, maintenance costs… some paradoxes  Environment______CO2 emissions, acoustics… Intermodality balance.  Comfort__________Aerodynamics, accelerations… 13 Workshop on High Speed.
