Tail risk differs from expected delay
An average delay can hide rare overnight disruptions. Review cancellation and rebooking exposure separately when missing the visit has a large consequence.

Visit Scenario Calculator
Compare two visit travel scenarios using fare, scheduled time, expected delay, protective buffer, and a user-entered value of time.
DOOR-TO-DOOR VISIT OPTIONS
Compare the whole travel burden instead of fare alone
A cheaper ticket can demand a longer transfer, earlier arrival, and larger disruption buffer. This page gives each travel scenario its own fare and time path, then converts time through an explicit personal planning value so the tradeoff is visible.

Travel scenario burden table
Generalized burden is a comparison device. The time value makes a preference explicit but does not turn personal time, fatigue, safety, or reliability into market prices.
| Scenario | Fare and fees | Scheduled hours | Delay plus buffer | Adjusted hours | Generalized burden |

CURRENT CALCULATION
Expose the time valuation instead of hiding it: formula, substitution, steps, and check
Hi = hsched,i + hdelay,i + hbuffer,i; Bi = farei + Hi x vtime; Delta = BA - BB
The page builds door-to-door planning time for each alternative, adds expected delay and a separately declared buffer, values those hours at the same personal rate, and compares the resulting generalized burdens.
HOW TO USE THIS DECISION TOOL
Compare two complete travel experiences on one boundary
- Use fares with the same refund, baggage, transfer, and mandatory-fee treatment.
- Measure scheduled time from the true starting door to the true destination, not terminal-to-terminal only.
- Keep expected delay separate from protective buffer: one is anticipated disruption and the other is deliberate margin.
- Choose a time value that reflects this decision and test more than one value when preference is uncertain.
- Review safety, accessibility, fatigue, and relationship impact outside the money-equivalent result.
SUBJECT FOUNDATIONS
Five layers in a door-to-door scenario
- Scheduled travel time
- Planned elapsed time from origin door to destination before disruption.
- Expected delay
- Average or planning allowance for additional travel time.
- Protective buffer
- Time intentionally reserved to protect a connection, appointment, or visit.
- Personal time value
- Entered decision weight applied consistently to both alternatives.
- Generalized burden
- Recorded fare plus adjusted travel hours multiplied by the time value.
MODEL BOUNDARY
Expose the time valuation instead of hiding it
Hi = hsched,i + hdelay,i + hbuffer,i; Bi = farei + Hi x vtime; Delta = BA - BB
The page builds door-to-door planning time for each alternative, adds expected delay and a separately declared buffer, values those hours at the same personal rate, and compares the resulting generalized burdens.
DECISION DEPTH
Why the lowest generalized burden may still be rejected
Comfort and accessibility are not time
A longer direct train may be preferable to a shorter sequence with stairs, security queues, or difficult transfers. Do not force every consideration into the time value.
Buffers have an opportunity cost
Arriving early protects the plan but consumes visit or work time. The model makes that reservation visible instead of treating it as free.
REAL USE CASES
Two route choices shaped by different constraints
Flight before an important family event
A higher fare and larger airport buffer may be justified when a missed arrival has a severe consequence. The generalized result is one input to that judgment.
Overnight rail instead of daytime travel
A slower elapsed route can preserve daytime together, but sleep quality and berth cost need explicit treatment rather than being assumed.
TERMS USED ON THIS PAGE
Scenario comparison terms
- Door-to-door
- Full journey from the actual origin to the actual destination.
- Delay allowance
- Expected extra duration attributable to disruption.
- Protective margin
- Reserved time added by choice to reduce schedule failure.
- Generalized cost
- Money amount plus nonmoney time expressed through an entered value.
- Sensitivity
- Change in the preferred option when an assumption changes.
- Tail disruption
- Low-frequency but high-consequence travel delay or cancellation.
EVIDENCE TO RETAIN
Preserve the itinerary behind every time input
Keep fare quotes, mandatory fees, origin and destination definition, scheduled legs, connection rules, transfer times, route delay evidence, buffer rationale, time-value decision, cancellation rights, travel date, and any accessibility or baggage assumptions kept outside the model.
LIMITS AND EXCLUSIONS
What the scenario burden omits
- It does not model delay distributions, missed connections, overnight disruption, or probability of arrival.
- Time value is subjective and should not be represented as an objective wage or legal loss.
- Comfort, accessibility, emissions, safety, and personal wellbeing are not included.
- Fare and schedule availability may change immediately after the comparison.

QUESTIONS SPECIFIC TO THIS DECISION
Questions about comparing visit travel scenarios
Why include both expected delay and buffer?
Expected delay describes anticipated disruption; buffer is a deliberate margin chosen to protect the plan. Combining them would hide why the hours were added.
Is the time value supposed to equal my hourly wage?
No. It is a personal decision weight. Wage, after-tax income, fatigue, and lost shared time are different concepts.
Can a zero time value be used?
Yes. That reduces the calculation to entered money fares while the time ledger remains visible for qualitative review.
Why use door-to-door time?
Terminal-only duration can omit access, parking, security, transfers, waiting, and final local transport that differ materially between modes.
Does the preferred result predict reliability?
No. It uses expected delay and buffer inputs but does not model the probability or severity distribution of disruptions.
Should we always choose the lower burden?
No. Verify safety, documents, accessibility, cancellation terms, comfort, and the consequences of failure before deciding.
IMPORTANT BOUNDARY
A generalized burden is not a safety or booking recommendation
This calculator provides transparent scenario arithmetic. It does not guarantee schedules, safe travel, entry eligibility, insurance coverage, accessibility, refunds, employer leave, or carrier performance.
