Transit operator relief schedule calculator

Calculate relief boundaries and shift-limit conflict blocks with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use relief boundaries and shift-limit conflict blocks to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Try the starting example

Trip blocks [duration minutes,relief allowed after block boolean]; enter JSON
[[60,true],[60,true],[60,false]]
User maximum continuous shift (minutes)
120
Relief boundaries (JSON)
[2]
Shift-limit conflict blocks (JSON)
[]

Try another scenario

Trip blocks [duration minutes,relief allowed after block boolean]; enter JSON
[[80,false],[80,true],[30,true]]
User maximum continuous shift (minutes)
100

Shift-limit conflict blocks (JSON)

Calculation method

Calculation method

Relief boundaries (JSON)

Track continuous work; when next block exceeds limit, relieve at the immediately previous boundary if allowed; output completed-block count.

Shift-limit conflict blocks (JSON)

Flag a block longer than limit, or an overrun whose immediately preceding boundary disallows relief.

Symbols and units
a
Trip blocks [duration minutes,relief allowed after block boolean]; enter JSON
b
User maximum continuous shift (minutes)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Fixed consecutive trip blocks and user-authorized boundary relief points; greedy relief when next block exceeds shift limit. Supported limits: All numeric inputs and computed intermediates must remain finite. Supported numeric input magnitude is zero or 1e-12 through 1e12 in absolute value; reject values outside this bounded range. All lists/JSON record tables are limited to 100 records unless a stricter bound is stated; reject malformed record arity and wrong member types. All numeric values must be finite. Lists contain at most 100 records; required lists must be nonempty. Rates, probabilities and fractions are entered as fractions, not percentages; fractions must be between 0 and 1. Use a single consistent user-selected currency for all amounts; no exchange-rate conversion.
