Definitions & Abbreviations - eRedekopp/trucker.alp GitHub Wiki
Rests
Break: used interchangeably with Rest. Try to use 'Rest' instead for standardization purposes, however some instances of this might still exist.
Short Rest: A brief rest required by law if driving for long stretches. Real law defines this as being at least 30 minutes long.
Early Short Rest: A Short Rest taken by a Trucker not because it is legally required, but because they need an opportunity to buy food, shower, etc..
Long Rest: Either a Sleeper Rest or a Restart Rest. We use the term Long Rest when we haven't yet decided which of the two we plan on taking.
Sleeper Rest: A rest overnight intended to be used for sleeping, eating, showering, etc.
Restart Rest: A long rest for more than a day intended to reset the clock on the driver's 60/70 hour rules.
Reset Rest: Interchangeable with Restart Rest. For consistency, try not to use this term.
Home Rest: An extended rest (i.e. longer than a restart rest) at the driver's home.
Locations
Truck Stop: A location intended for overnight parking for truckers with facilities, food, etc.
Gas Station: A location with refuelling facilities suitable for commercial trucking, as well as a basic convenience store, but no overnight parking.
Rest Area: A location with overnight parking available to truckers but no services available such as showers or food.
Unsafe Location: A parking location that is not a truck stop, gas station, or rest area. This can be imagined to be a highway ramp, an abandoned lot, or some other ad-hoc parking location when no other parking is available.
Shipper / Receiver: A location where a trucker either picks up or drops off a load. In the model, each city is assumed to have a single shipper/receiver at the city's centre.
Destination: When this word is used, it typically means the shipper/receiver toward which a Trucker is currently travelling as opposed to its next stop along the way.
Time Periods
Driving Period: The period of time in between Home Rests.
Detention: Time spent at the shipper or receiver waiting to start driving.
Regulations & Violations
Parking Violation: An incident where a trucker parks in an unsafe location because no other options are available.
Hours Violation: An incident where a trucker drives or is on duty for more hours than allowed by regulation.
N-Day Rule: The regulation defining the total number of duty hours a trucker may work in N days. For the purposes of this rule, a day is simply the 24-hour span between two midnights with no consideration for the time or duration of a trucker's breaks.
7-Day Rule: See N-Day Rule
8-Day Rule: See N-Day Rule
60-Hour Rule: Interchangeable with 7-Day Rule.
70-Hour Rule: Interchangeable with 8-Day Rule.
This is the common parlance in the trucking industry, however it refers specifically to the current regulations and would have to change if we considered a scenario where the regulations were different. Thus, we use "N-Day Rule" more commonly in this model because it is more generic. However, you may see occurrences in the model where the N-day rules are referred to this way.
