SPEED AS A CONSEQUENCE OF TECHNOLOGICAL DEVELOPMENT

TECHNOLOGY IS CONTINUOUSLY PROVIDING SOLUTIONS- MECHANICS,

MATERIALS, ENGINES…- FOR INCREASING SPEED

9Workshop 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)

10Workshop 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

OPTIMUM SPEED IN DIFFERENT TRANSPORT MODES

12Workshop 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…
