Multi-lane free flow in Malaysia
The multi-lane free flow (MLFF) is a system that allows free-flow high-speed tolling for all highway users. With MLFF, current toll lanes at toll plazas can be replaced with ordinary multilane road segments. By using tags with readers at gantry across the highway to detect vehicle and deduct toll using the existing Electronic Toll Collection (ETC) when fully implemented. Using only video and automatic license plate recognition it is also possible to have a MLFF system without using tags and readers. This type of solution is implemented in Stockholm for congestion charging purposes.
Benefits
By implementing the MLFF system, traffic congestion at toll plazas can be reduced as the system allows free flow high speed toll system.
Differences
| No | Touch 'n Go card TnG | Smart TAG TAG | MLFF Trial Tag |
|---|---|---|---|
| 1. | Card with embedded microchip | 2 piece on-board unit (OBU) | Two & Single piece on-board unit (OBU) |
| 2. | Contactless card with antenna | Use infrared transmission | Use microwave transmission (Active & Passive) |
| 3. | Used at dedicated toll lanes with automatic barriers | Used at dedicated toll lanes with automatic barriers | No toll lanes / automatic barriers, use gantry system |
| 4. | Reduced speed at Touch ‘n Go lanes | Reduced speed at SmartTAG lanes | Faster traveling speed / Utilization of current assets to reduce capital investment for MLFF |
MLFF trial run
The MLFF trial run is carried out by Teras Teknologi (TERAS) under instruction by Malaysian Highway Authority (MHA) to test, evaluate and report the effectiveness of the new highway system and technology before the start of gradual implementation at all highways.
The MLFF trial run will be carried out for the next 6 to 12 months from December 2008. A report on system feasibility, user acceptance and behavioral patterns, enforcement mechanism and proposed project financing will be submitted for cabinet recommendation and approval by Parliament.
