Based on Road Ownership and Type

• Toll plazas are classified as national, state, or private depending on the road type.
  
• National highway toll plazas are managed under the authority of NHAI.
  
• State highway toll plazas are governed by respective state road agencies.
  
• Private road operators manage tolls on BOT or concession-based projects.
  
• Each type follows different toll collection rules and revenue structures.
  

Based on Lane Configuration

• Toll plazas are categorized into single-lane, multi-lane, or plaza-type setups.
  
• Single-lane tolls are used in low-traffic rural areas.
  
• Multi-lane plazas are built on busy highways and expressways.
  
• High-speed electronic lanes are reserved for FASTag users.
  
• Dedicated lanes for commercial or oversized vehicles are often included.
  

Based on Technology Used

• Toll plazas are classified as manual, semi-automatic, or fully electronic.
  
• Manual plazas collect tolls through human-operated counters.
  
• Semi-automatic systems combine manual input with digital billing.
  
• Fully electronic toll plazas use RFID and sensors for contactless collection.
  
• Hybrid plazas may operate both manual and electronic lanes simultaneously.
  

Based on Location and Function

• Entry/exit tolls are set at highway entry or exit points.
  
• Mainline toll plazas are located on the main stretch of the highway.
  
• Interchange tolls are placed at connecting roads or flyovers.
  
• Bypass tolls help divert traffic around city centers.
  
• Some plazas serve city limits, while others are exclusive to inter-state highways.
  

Based on Traffic Volume and Revenue

• Toll plazas are also grouped by traffic density and income generation.
  
• Low-revenue plazas are located in less-traveled routes.
  
• Medium-volume plazas are typically found on state or feeder highways.
  
• High-revenue plazas exist on industrial corridors and intercity expressways.
  
• Classification helps in resource allocation and monitoring priorities.
