Example figures: duration of low current velocity

Explanations

Period of the time during which the magnitude of current velocity lies below a given velocity limit.

• left top: value of the parameter for the 1st class [limit velocity: 0.1 m/s].
• right top: value of the parameter for the 3rd class [limit velocity: 0.5 m/s].
• left bottom: value of the parameter for the 5th class [limit velocity: 0.9 m/s].
• right bottom: value of the parameter for the 7th class [limit velocity: 1.3 m/s].

Examples

current velocity < 0.1 m/s	current velocity < 0.5 m/s

current velocity < 0.9 m/s	current velocity < 1.3 m/s
