How MTR can attract many passengers.It can include passenger psychological and the MTR transportation tool service performance and beneficial factors to influence the passengers to choose which kind of transporation tool to catch. On the commuter departure time choice of any reference point researching hand, the departure time decisions of communters are of fundamental importance of peak period MTR traffic congestion. However, whether on the demand side, MTR underground train congestion relief measures, such as MTR ticket fare to every terminal station needs to be charged cheaper fare or discount fare in the peak (busy) time every day. To aim to attract many passengers to choose to catch MTR Underground train public transportation tools, substitute to choose other public transportation tools in the peak time. Over the past decades, there have been very active research efforts in the departure time problem, both in econometric modeling and dynamic user equilibrium fields. Although, these works provide valuable insights into dynamic commuter decision making, they do not identify the commuters' response to gains and losses related to whole actual arrival time to reference points who may have relative. The appliability of the reference point hypothesis of prospect theory to the commuter's departure time decision making to obtain a better understanding of how departure time choice in MTR platform during their waiting underground train arrival time. However, every MTR underground train actual arrival time and deviation variables related to reference points ( gains and losses) are the key factors in the departure time choice model. How the MTR underground train of every communter's daily departure time decision can be modelled when the reference point hypothesis of prospect theory. The MTR underground train's schedule delay is defined as the difference between the preferred arrival time (PAT) and the actual arrival time (AT) for a given MTR communter. In a daily MTR commute, a commuter in the indifference band actual arrival time is an essential feature of MTR schedule study. Two reference points are the earliest acceptable arrival time and the work starting time for a given MTR platform waiting passengers. In psychological view point, prospect theory proposes that the displeasure of a loss is perceived or greater than the pleasure of a gain of the same attitude and therefore, the value function is stronger for losses than gains. To conclude, it seems that if MTR waiting passengers need not spend long time to wait underground train arrival in platform and it can provide seats to let them to sit down in the busy (peak) crowding time. It will make them to feel pleasure, even the MTR ticket fare is not fair and reasonable to charge higher fare to compare other kinds of public transportation tools fares. So the peak waiting time factor can influence the passengers to choose other kind of transportation tools to catch easily. Moreover, MTR's two reference points are the earliest role. Similarly a loss is observed when the MTR platform waiting commuter experiences or actual arrival time which is beyond that the MTR schedule time. Due to that a MTR waiting commuter is as an early side arrival of whose actual arrival time is earlier than whose preferred arrival time. In general, passenger transportation choice consumption behavior is similar to alcohol choiceconsumption behavior.Because some passengers choose to catch the kind of transportation tool, it is habit cause. Such as some alcohol consumers who often drive the brand of alcohol, it is habit cause also.
