A longer metro network does less for riders who cannot reach a station

India’s metro expansion has made fast trips possible across more cities. An August government account puts the network above 1,155 kilometres across 26 cities and says daily ridership had crossed 1.15 crore. For someone travelling to work, the value of the network depends on how much of the city is reachable within a fixed budget of time and money. The next gains can come from buses, walking routes and transfer design that let more people use the rail capacity already in place.

Count the journey a worker actually makes

A rail operator records a boarding. The worker first chooses whether to reach the station and whether the connection works in both directions. A poorly lit crossing, an unreliable feeder or a fare charged separately can make an apparent connection unusable. If buses stop running before a late shift ends, service that looks good at the morning peak can still leave many workers dependent on a more expensive mode. The aggregate metro ridership figure cannot reveal those missing trips.

A fare card can simplify payment across modes when operators accept it. Fare integration is a different choice about the total amount a transfer passenger pays and how revenue is divided. Two agencies may agree to accept the same card and continue to charge a full fare on each leg. A transfer discount can reduce the total fare, with a settlement rule needed to compensate each service. A clear record of journeys and allocation helps agencies evaluate the extra passengers gained. Parliamentary reply, National Common Mobility Card

A short feeder can change the mode choice

Consider an illustrative commuter whose metro ride takes 25 minutes. Walking to the station takes 20, waiting and changing trains takes 12, and the last walk takes 13. The trip is 70 minutes. A well-timed feeder and a safer access path can reduce the first leg and transfer together by 15 minutes, giving a 55-minute trip. If the main alternative takes 60 minutes, the preferred mode can change without a minute being saved on the train itself.

Time savings can also affect labour participation. A household balancing a child’s school hours or a fixed care schedule may be unable to accept a shift requiring 70 minutes of travel each way. Cutting the trip to 55 can make the schedule feasible. Other workers would simply value the extra time. A benefit calculation should consider changes in reachable jobs and shifts alongside existing riders’ time savings.

Choose where to add frequency

The strongest case for prioritising the rail extension is that density, distance and road congestion can make a feeder inadequate for some trips. An extension can provide useful capacity and attract travel that buses cannot handle. The comparison should include frequency improvements, better interchange design and pedestrian access for the trips each investment serves. A lightly used branch may be difficult to justify if feeder improvements open a similar range of jobs at lower cost. A high-demand corridor with severe bus delay can lead to the opposite conclusion.

Map the jobs and public services reachable within 45 or 60 minutes under actual schedules, including walking, waiting and transfers. Repeat at the start and end of different shifts. Compare before and after adding a feeder or revising a fare. Record missed connections and whether improvements persist when demand rises. If travel times fall mainly for users already close to a station, the distribution of benefits remains narrow. If more low-income neighbourhoods gain reliable access and repeat use increases, the improvement has raised the return on the rail network.

The evaluation should count riders who gain a useful second journey as well as new users. Someone who already takes the metro to work may be able to reach a different job, a clinic or an evening class after the network becomes easier to transfer through. Boardings alone will count those changes unevenly.

Track kilometres to see where the rails reach. Track feasible door-to-door journeys to see which people they serve.
