The side area or edge of a road that directly borders the roadway.
Wegen einer Panne musste er sein Auto am Straßenrand abstellen.

This word is made up of 'Straße' (road/street), the linking element '-n-', and 'Rand' (edge). So it literally describes the edge or side of a road.
Am Straßenrand blühten wilde Blumen.
Wildflowers were blooming at the roadside.
When describing a position or place at the roadside, the preposition 'an' with the dative is almost always used: 'am Straßenrand' (at the roadside).
Die Kinder warteten sicher am Straßenrand auf den Schulbus.
The children waited safely at the roadside for the school bus.
Common verbs used in connection with 'am Straßenrand' (at the roadside) are 'stehen' (to stand/be), 'parken' (to park), 'warten' (to wait), and 'liegen' (to lie/be lying).
Wir mussten am Straßenrand anhalten, um auf die Karte zu schauen.
We had to stop at the roadside to look at the map.
side of the street
'die Strassenseite' and 'der Strassenrand' both describe a side area of a street or road. 'Strassenseite' refers more to one side or the other side of the street, for example the side where a house is located. 'Strassenrand' refers more specifically to the edge directly next to the roadway, often where cars stop, trash bins stand, or grass begins. The words can be confused because neither refers to the middle of the street. As a practical rule: for 'left or right of the street', 'Strassenseite' fits; for the edge directly beside the roadway, 'Strassenrand' fits.
