PMPML Fleet Monthly Depotwise reports

Fleet data per depot per month across 22 months from January 2023 to June 2025. Coverage is not continuous — Jan–Mar 2024 and Nov 2024–Mar 2025 are missing from the source reports. This period falls during post-COVID ridership recovery — PMPML ridership had collapsed during 2020-21 lockdowns and was still rebuilding toward pre-pandemic levels through 2023-2024.

This page lets you explore individual depot metrics over time. For a cross-depot comparison, see Depot Performance.

Known data quality notes: February 2023 "All Traffic Earning" was corrupted in the source PDF extraction (tabula column shift); it has been imputed as ticket + pass + student earnings. December 2023 fleet utilization exceeded 100% at Pune Station (200%) and Nigadi (117%) — a source formula quirk; capped at 100% in all SQL. April 2023 ticket-only EPK was corrupted; imputed from earnings/km. January and March 2023: the "Sanctioned" and "Operated" schedule columns are swapped for 8 depots — schedule queries use GREATEST/LEAST to reconstruct the correct values. November 2023 Nigadi "Gross KMs per own bus" is anomalously high (541 km/bus/day vs. typical 150–200); the Total Gross KMs (Diesel+CNG+E) column is structurally unreliable and is not used in any visualisation here — use Total Dead KMs (Diesel+CNG+E) (which is independently recorded and reliable) if dead-km data is needed.

Earnings Analysis

Passenger Metrics

The growing share of non-ticket riders (passes, contracts, mobile app) indicates a maturing commuter base. This is a double-edged trend: regular commuters are good for ridership stability, but passes are typically discounted relative to tickets, compressing per-passenger revenue.

Revenue Sources

Fuel & Energy Efficiency

Fleet Composition by Fuel Type

Counter to typical "green fleet" expectations, PMPML's own fleet is shifting toward diesel and away from CNG. Diesel's share grew from ~5% in early 2023 to ~16% by mid-2025. The source reports stopped including a direct diesel-km column after December 2023; 2024–2025 figures are estimated as KMPL × diesel consumption (own fleet) — a proxy that agreed within ~20% of the direct values in 2023. E-Bus km reads as zero here because the contracted e-bus fleet (Olectra Greentech) runs under a separate reporting stream — see the E-Bus page.

Fuel Efficiency Trends

Note: Diesel efficiency is in km/litre and CNG in km/kg — these are not directly comparable since diesel and CNG have different energy densities (~36 MJ/litre vs ~48 MJ/kg). These charts track each fuel type's efficiency trend over time, not relative performance between fuels.

Accident Metrics

Breakdown Analysis

Tyre Life

Average kilometers per new tyre measures how hard the fleet is being worked and how good the road/driving conditions are. Lower tyre life = more demanding routes or harder driving. Annual_Statistics shows tyre life improved from 65,595 km to 72,864 km (FY 2023-24 → 2024-25); the monthly view shows whether that improvement was gradual or step-change.

Engine Oil Efficiency

Engine oil km/litre (km operated per litre of engine oil consumed) is a proxy for engine health: degrading engines consume oil faster and return lower km/litre. Higher values indicate better-maintained engines. Coverage is partial (~53% of depot-months have non-null values); months with no oil consumption recorded are excluded from the aggregate.

Staff & Workforce

PMPML's prescribed staffing norm is 9.0 bus staff per vehicle (1.0 admin + 6.5 traffic + 1.5 workshop). The actual system-wide ratio runs around 4.0 — roughly half the norm. The traffic sub-ratio (drivers, conductors, supervisors) bears the most weight: actual ~3.1 vs norm 6.5. The admin sub-ratio is the most severely understaffed: actual ~0.17 vs norm 1.0. Workshop staffing sits at ~0.6 vs norm 1.5.

This persistent half-norm staffing constrains both operations (fewer drivers = fewer schedules can run) and safety oversight (fewer supervisors per bus). It is partly structural — PMPML relies on PPP and hired fleet whose drivers are not counted in PMPML's own staff ratios — and partly reflects recruitment/retention constraints within a corporation that cannot freely set salaries.
