How to document it
2026 reference point
Metro İstanbul publishes current network maps and maps of lines under construction. When evaluating metro proximity, distinguish an operating station from a line under construction or only planned, and measure actual walking time rather than straight-line distance alone.
Common failure modes
Commute Time Location Analysis
Core point
Measure commute time door-to-destination at peak hours rather than straight-line distance to a station or main road.
How to verify it
Separate walking, waiting, transfers and congestion from in-vehicle time and repeat the measurement at different days/times.
Decision impact
Distinguish an operating transport line from one under construction or merely planned; future infrastructure is not current service for a housing decision.
Measure commute time door-to-destination at peak hours rather than straight-line distance to a station or main road.
Commute time should be measured door to door
Distance to a station is not enough. Record walking time from the building to the entrance actually used, waiting, transfers, in-vehicle time and the final walk to the destination. Use Metro İstanbul maps to establish operating lines, but test the real journey during work hours in both directions. Note barriers such as steep grades, highways, unsafe crossings or a station entrance located on the opposite side of a large junction.
Reliability matters as much as the average. Test an alternative if the main line fails and compare bus, metrobüs or driving options and the burden of multiple transfers. For a daily office or school trip, convert the time difference into annual hours rather than using the vague label “central location.” A future line should remain a separate potential improvement and should not be included in current commute time until it actually operates.
Real commute time is a distribution, not one map number
Test representative journeys: workday morning, evening and weekend, and include walking, waiting and transfers rather than vehicle time alone. Build an alternative route for failure of one line and note taxi/private-car cost where public transport ends early. A family may need school or childcare journeys; an investor should test employment clusters relevant to the expected tenant. Two districts should not both be labelled “20 minutes to metro” when one route depends on an infrequent feeder bus, difficult slope or a transfer that materially increases variability.
Commute time should be measured door to door at the hours the occupant will actually travel, including walking, waiting and transfers; distance to the nearest station alone is not a commute measurement.
What to inspect Test the micro-location at different times and by more than one route; record actual walking/driving time, barriers and alternatives.
