Closed toll systems

Closed toll systems require expressway users to pay toll charges based on the distance travelled and the class of vehicle used. Drivers collect a transit ticket at the toll plaza on entering the expressway. The ticket, which is surrendered at the exit toll plaza, is used to calculate the amount of toll payable based on the distance between the point of entry and exit. Toll fares are charged based on the distance between the entry plaza and the exit plaza plus the distance from the plaza to the Limit of Maintenance Responsibility (LMR).

Closed toll systems are well suited to inter-urban highways on which long distance traffic volumes are high. About 786 km of the North South Expressway, including the 35 km stretch of the North Klang Valley Expressway, are operated on a closed toll system for this reason


Open toll systems

Open toll systems require expressway users to pay a fixed toll charge at the toll plaza based on the class of vehicle used. The user is free to exit the expressway at any junction or to continue on to the next toll plaza or toll collection point.

Semi urban highways with numerous junctions or intersections serving short distance trips usually employ an open toll system. On the North-South Expressway, this system is used at the following locations :

Batu Tiga and Sungai Rasau on Federal Highway Route 2
Bukit Kayu Hitam
Jitra
Senai
Kempas
Johor Causeway
