High Speed Train
- Speed > 200 km/h
- exploitable almost only on dedicated infrastructure
- high strength tracks or ballast-free tracks
- high precision alignment
- limited curvature radii and limited slopes
- high electric power required
- average speed is highly dependend on amount of stops
Bus - Advantages and Disadvantages
Advantages:
- Flexibility of infrastructure usage
- Less and faster infrastructure setup
- Greater friction --> better adhesion --> higher de-/acceleration
- good service in rural areas with frequent stops
Disadvantages
- Mixed traffic; congestion effects; pedestrian crossing and traffic lights
- Adhesion forces (rolling friction); quality of road
- Limited length/capacity
Metro - Advantages
+ Seperated infrastructure
+ Very high capacity
+ Large doors, level acces --> short dwell times
Why is Public Transport Supplied with Lines?
Public = Usable by All
--> Requires a Driver
--> High fixed costs
--> Bundle Demand
--> Organise in Lines
