Road Network
Road Network sits in the Mobility phase of CityOS — AJG's synthesis of municipal-administration practice across 1,584 tracked cities. Road hierarchy: expressways (>120 kmph) → arterials (60-80) → sub-arterials (40-60) → collector → local. Ring roads (Outer Ring · Peripheral Expressway) decongest core. Complete-streets approach integrates ped/cycle/transit. Maintenance backlog is universal challenge — typical 20-40% road segments need rehab. Scale: USD 1-50M per km depending on type. Time horizon: 1-5 yr per segment. Multilateral coverage: 197 countries × 1,584 cities (T1/T2/T3).

Frequently asked about Road Network
What is the typical scale of Road Network?
USD 1-50M per km depending on type
How long does road network take?
1-5 yr per segment
Who are the primary actors involved?
pwd-mcgm-municipality, nhai-state-highway, concessionaires, metropolitan-area-authority.
Does Road Network apply across all 197 countries?
CityOS is multilateral by construction. Frameworks adapt to legal, fiscal, and institutional context — but the structural slices are universal. City-specific applications surface via /os/cityos/country/{country}/.
How does this relate to AJG's broader platform?
CityOS complements TradeOS (operations) and GovOS (rules) by adding the urban-management lens. Cross-OS quadruples — DealOS × TradeOS × GovOS × CityOS — surface strategic + operational + regulatory + spatial views together.
