🤖 AI-generated city profile, summarising the source-checked entries below — how this works

Tehran's longest-running smart-mobility effort is its central Traffic Zone, a permit-only cordon around the city core dating to 1979 that the municipal Tehran Traffic Control Company automated from 2010 with more than 300 licence-plate-recognition cameras at 104 entry points. In May 2018 the city replaced daily permits with a charge per day of entry, scaled by time of day and how long drivers stay, and in June 2019 the surrounding odd-even ring became a second charged zone.Tehran's longest-running smart-mobility effort is its central Traffic Zone, a permit-only cordon around the city core dating to 1980 that the municipal Tehran Traffic Control Company automated from 2010 with more than 300 licence-plate-recognition cameras at 104 entry points.

Compare with other cities

🇮🇳 New Delhi GRAP: Air Quality Readings as a Legal Trigger Delhi's AQI thresholds carry automatic legal force; Tehran's readings go to emergency sessions that decide closures case by case. 🇮🇩 Jakarta Court-Ordered Air Quality Monitoring Jakarta's court-ordered network also triggers nothing automatically — same rung of the reading-to-consequence ladder as Tehran. 🇸🇬 Singapore Electronic Road Pricing (ERP) Network Two of the oldest city-centre access charges: Singapore's 1975 licence scheme and Tehran's 1980 permit zone, both later camera-automated. 🇬🇧 London Central London Congestion Charging Scheme Tehran ringed its centre with permits in 1980, decades before London's 2003 charge; it went ANPR in 2010 and time-based pricing in 2018.

🇹🇭 Bangkok: Bangkok PM2.5 Monitoring & Graduated Response Both cities close schools on bad readings but lack levers over the biggest sources — Bangkok's cross-border haze, Tehran's mazut plants.
🇦🇪 Dubai: Salik Dynamic Congestion Pricing Two Middle East schemes that price by time: Tehran's charges vary by entry time and duration (2018); Dubai's Salik went dynamic-by-hour.
