Usage tips
Compound word
The word is a compound of 'die Straße' (the road/street, in the form 'Straßen-') and 'der Verkehr' (traffic). So it literally describes traffic that takes place on the road.
EXAMPLE
Kinder müssen lernen, im Straßenverkehr vorsichtig zu sein.
Children have to learn to be careful in road traffic.
Uncountable noun
'Straßenverkehr' (road traffic) is an uncountable noun (a singulare tantum). It is therefore almost never used in the plural or with the indefinite article 'ein' (a/an). People speak of 'Straßenverkehr' in general.
EXAMPLE
In Großstädten gibt es oft dichten Straßenverkehr.
In big cities, there is often heavy road traffic.
Typical collocations
Common adjectives are 'dichter' (heavy/dense), 'fließender' (flowing), or 'stockender' (stop-and-go) Straßenverkehr. Typical verbs are 'am Straßenverkehr teilnehmen' (to participate in road traffic), 'den Straßenverkehr beobachten' (to observe road traffic), or 'den Straßenverkehr regeln' (to direct/regulate road traffic).
EXAMPLE
Wegen des Feiertags herrschte heute nur wenig Straßenverkehr.
Because of the holiday, there was only light road traffic today.

Strassenverkehr vs Verkehr
traffic / contact
'Verkehr' and 'Strassenverkehr' can both mean the movement of vehicles and people. However, 'Verkehr' is more general. It can be about cars, trains, airplanes, ships, or also goods and people. 'Strassenverkehr' is more specific and refers only to what happens on public roads and squares: cars, trucks, bicycles, and pedestrians. Learners may confuse the words because in everyday life people often simply say 'Verkehr' when they actually mean traffic on the road. If you are speaking generally, 'Verkehr' fits. If it is clearly about roads, 'Strassenverkehr' is more precise.
Strassenverkehr
Kinder lernen in der Schule, wie sie sich im Strassenverkehr sicher verhalten.
Children learn at school how to behave safely in road traffic.
Verkehr
Wegen des Schnees war der Verkehr in der ganzen Stadt sehr langsam.
