Oncoming traffic
Two-way traffic is the name for two different situations:
- A form of the main run that is mainly used in national freight transport . For this purpose, a shipping company will arrange a meeting point in the middle of two spatially opposing tours in order to swap the load there. The vehicles then complete the second half of the other vehicle's tour. Parking places and rest areas along highways, for example rest areas or truck stops, are suitable as meeting points . If the vehicles have to take a detour to get to the meeting point or if there are no options for quickly changing the load (such as swap bodies ), the time required increases accordingly. It is advantageous that the vehicles return to their starting point and are available again there. The driver saves waiting times far from home or long empty trips.

Two modes of transport meet on a (relatively narrow) traffic route and pass each other. A wider point on an otherwise single-lane traffic route is called a siding or siding . A distinction is made between two types of encounter: that in different directions and overtaking. Depending on the length of the pass and the difference in speed between the two participants, the slower vehicle must stop in order to allow the faster vehicle to overtake .
- to oncoming traffic in tunnels to avoid to build if possible, a tunnel in each direction (for high-speed trains traffic tunnels, this is because of the pressure wave front and the suction essential behind a train)
- two ships pass each other on a waterway . Especially when the meeting point is in a bend in the river or when two large ships meet, the width of which fills almost the entire fairway , this can be navigationally demanding. On some river sections there are alternative areas where the fairway is wider. For example, (as of May 2013) a seven-kilometer-long and 400-meter-wide alternative point is planned on the Lower Elbe.
- Trains can meet each other safely on multi-track railway lines (see above for pressure problem in the tunnel). There is only one special feature: some old railway bridges are not designed to carry two trains at the same time.
