Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-6716dc1570f0e8db quantitative

Against the San Cristóbal control district, quality of life rose 5.81 points for women (95% CI 2.47-9.14) but not significantly for men (0.96, 95% CI -3.65 to 5.57)

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The TrUST natural experiment surveyed 2,052 adults in Ciudad Bolívar and in San Cristóbal, a comparable hillside district with no cable car, before and after opening.
Caveat: 1,679 of the 2,052 recruited adults completed follow-up.

Establishes the design: 'a prospective, quasi-experimental study using a mixed-methods approach' comparing intervention (Ciudad Bolívar, within 800 m of stations) with control (San Cristóbal, selected for similar topography, comparable planned cable car, similar low socioeconomic status and high crime). Baseline Feb-Nov 2018, follow-up 2019. Funders include Wellcome Trust and NIH; institutions Universidad de Los Andes, UC Berkeley, Stanford, Drexel. This is the source for the control-group claim.

Source for the travel-time figure (mandatory-trip one-way time 110.0 → 90.2 minutes in the intervention area) and for the null result: transport walking meeting WHO guidelines rose 11.1 points in the intervention area against 8.0 in control, adjusted OR 1.1, p=0.38 — not significant; accelerometer-measured moderate-to-vigorous activity showed no change. 2,052 recruited, 1,679 followed up. Note the travel-time figure is a within-group before/after number, not a difference-in-differences estimate.

Source for the quality-of-life effect sizes, which ARE time-by-group interactions against the control district: females +5.81 points overall (95% CI 2.47-9.14), general health +5.49, psychological domain +3.48; males not significant (0.96, -3.65 to 5.57). No significant effect for either sex on physical health, social relationships or environmental domains. Sample 1,679 (825 intervention, 854 control), 62.8% female, mean age 43.5.

Independent difference-in-differences event study comparing residents within 500 m of opened stations against residents near FUTURE planned stations; 662 million GPS pings from 902,000 phones, July 2018-June 2019. Finds ≈6.5 additional trips per person per month (≈5%) and +3 points of interest visited, but limited evidence of socioeconomic mixing and no statistically significant increase in visits to high-income neighbourhoods.

Authority-reported figures: 44.7 million trips over six years, around 25,000 people per day, ≈37,600 service hours, 163 cabins, 24 towers, four stations (Tunal, Juan Pablo II, Manitas, Mirador del Paraíso), ≈13 minutes end to end, capacity 3,600 passengers per hour per direction. The city gives the length as 3.25 km here; other accounts give 3.34 km, hence 'about 3.3 km' in the entry. The 3,600/hour figure is design capacity and is deliberately NOT used as a ridership number.

Establishes the fare mechanism: a single unified fare of COP 3,550 effective 14 January 2026 (a 10.9% rise), with TransMiCable included. Transfers between trunk buses, zonal buses and the cable car are free within a 125-minute window — but only with a PERSONALISED TuLlave card; non-personalised cards pay the same base fare without the transfer benefit. The card itself is covered by a separate atlas entry.

Counterweight on reliability: service failed to open at its usual 04:30 start on Friday 3 July 2026 and was still down after ≈28 hours on Saturday 4 July; specialists from the Austrian manufacturer were involved and no root cause was disclosed. TransMilenio reinforced zonal buses as a substitute. The article gives no availability history.
