I have received complaints from members of the public that while the same day return fare discounts offered under the bus fare adjustment mechanism , which allows fares to go upward and downward , have been formally implemented since 19 february this year , the bus companies concerned need a longer lead time to modify the software of their octopus systems , so as to ensure that the same system applies consistently across different bus companies , and hence will not implement the fare discounts on jointly operated cross - harbour routes until july this year . they consider that this arrangement is unfair to the bus passengers concerned
本人接获市民投诉，指在巴士票价可加可减机制下提供的即日来回票价折扣，虽然已在本年2月19日正式实施，但有关的巴士公司却需要较长筹备时间改装其八达通系统的软件，以确保不同巴士公司可统一应用同一个系统，以致要到本年7月才开始在联营过海隧道巴士路线实施票价折扣，认为此安排对有关的巴士乘客不公平。
