A $100 million funding request for a feasibility study on electronic road pricing is to be tabled to the Legislative Council finance committee next month. The study, expected to take about two years, will assess the requirements, cost effectiveness and consequences of the system, taking into account transport planning, system technology and public acceptance. Electronic road pricing controls the use of vehicles by charging variable fees for entering congested areas or using heavily overloaded roads at peak times. Special emphasis would be placed on safeguarding the privacy of motorists using the system, the Government said. Consultants had to be commissioned for the study because the Government lacked the expertise, it added.
