Biggest Gap

Health → Cycling

Cycling share at just 4% of trips, compounded by only 45% of roads have paved footpaths

Recommendation

Building protected cycle networks + bike-share systems could shift trips from private vehicles

Action Guide

Everyone

Actions anyone can take to improve transport quality of life

Track your active commute

Log every walk, cycle, run, and transit trip with Altmo Tracker. Your activity contributes to your city's Walking %, Cycling %, and Sustainable Mode Share — the indicators planners actually use.

Start tracking

Run a free community challenge

Get five friends or fifty neighbours together. Free walking or cycling challenges with a leaderboard, GPS tracking, and a discussion forum — built for RWAs, cycling clubs, and community organisers.

Create a challenge

Rent a bicycle

Borrow a bicycle from a local owner through Altmo Rentals. Daily, weekly, and monthly rentals — try cycling your commute, take a longer trip, or skip the upfront cost of buying your own bike.

Rent a bike

Map walking paths

Contribute to OpenStreetMap by mapping footpaths, crosswalks, and pedestrian signals in your neighbourhood. Better mapping data drives Footpath Coverage scores higher.

Open map editor

Report infrastructure issues

Report broken footpaths, missing streetlights, or blocked cycle lanes to your municipal corporation. Documented complaints drive maintenance budgets and Footpath Coverage gains.

File a complaint

Active Citizen

Advocacy and participation in urban transport decisions

Join neighbourhood groups

Connect with people in your neighbourhood. Local groups discuss issues, organise events, and represent residents in conversations with the municipal corporation — from transport and footpaths to street safety.

Find groups near you

Join a cycling advocacy group

Connect with local cycling communities who organise rides, push for cycle infrastructure, and represent cyclist interests in policy discussions — direct lever on Cycling % and Cycle Infrastructure km.

Find local groups

Participate in public consultations

City Master Plans, Comprehensive Mobility Plans, and Smart City proposals have public comment periods. Advocate for pedestrian and cyclist safety measures and influence Sustainable Mode Share targets.

Corporate

Actions for employers and organisations to support sustainable commuting

Build a corporate active-mobility programme

Cycle-to-work benefits, fleet management, employee challenges, and BRSR-ready CO2 dashboards in one corporate plan. Moves your team's Walking %, Cycling %, and Sustainable Mode Share — with audit-ready Scope 3 commute data.

See Altmo for organisations

Sponsor a city challenge

Run a branded walking or cycling challenge for your customers or as a city-wide activation — leaderboards, GPS-verified activities, ESG-ready impact data. From ₹500/month self-serve, or full-service Managed for branded events.

See partner plans

Subsidise transit passes

Offer metro/bus pass subsidies as part of employee benefits. Shifts commute mode share, reduces parking demand at your facility, and improves the city's PM2.5 and NO2 indicators.

Urban Planner

Data-driven actions for transport planners and policymakers

Publish open transport data

Release bus routes as GTFS, share traffic count data, and publish accident locations. Open data enables evidence-based advocacy and academic research.

MobilityData catalogue

Compare your city to peers

Benchmark against the other 9 cities on Altmo Intelligence using 19 indicators across Health, Accessibility, Environmental, and Mobility. Use the scenario engine to model intervention outcomes before committing budgets.

Compare cities

Conduct pedestrian safety audits

Systematic walkability audits identify missing footpaths, dangerous crossings, and accessibility barriers. The iRAP Star Rating methodology provides a standardised framework.

iRAP methodology

Design protected cycle infrastructure

Physically separated cycle tracks (not painted lanes) are proven to increase cycling mode share. Refer to the Indian Road Congress IRC SP-110 guidelines.

Improve transit accessibility data

Map transit stop accessibility features (ramps, tactile paths, shelters) to enable inclusive route planning for persons with disabilities.
