Encoding Parking Sign Patterns
Signs of this type (typically denoted a R8 category types in MUTCD) are used to indicate that vehicle
parking is (or is not) allowed in designated places for denoted times and periods. The general pattern is:
<duration limits><optional qual><parking><time and day limits><class of vehicle>
<qualifier data><applicable locations>
The duration limit sets the allowed parking duration, if any. The optional qual entry is typically the term
“no” when present to indicate that parking is to be prohibited. The parking is the critical “parking” code
entry (value 4120 from Parking Information). The time and day limits restricts the application of the
parking rule to selected hours and days. The class of vehicle allows the application of the parking rule to
selected vehicle types or traveler classes, such as trucks. The qualifier data is the can be used to set
additional time limits or exempt times and users from the rule. The applicable location applies the rule to
local spatial areas such as one side of the street, from the sign to another point, etc., and may contain arrow
information.
In constructing signs using these patterns the following rules shall be observed:
The sign expression shall be started with an MUTCD sign type when needed
Any time of data restrictions shall precede any class of vehicle restrictions
Location modifiers which determine how the sign is applied to the local area shall be last
The unit’s term shall be present only when it is preceded by a numerical value.
When there is no unit code present the value shall be in units of Hours.
