A high number of accidents in railway level crossing causes loss of life and material. Furthermore, the losses are also experienced by users of traffic on the highway such as disturbance in the form of delay which can lead to increase the length of travel time where the vehicle will stop, and give impact to the emergency queue vehicle at railway level crossing. Considering those problems, there has been build two models which are: the first model is the queuing of traffic length and with considering the length and speed of the train, and the second model is the queuing of traffic with considering the gate closing time. The methodology applied was an observation on field and survey data and then calculation from Road Capacity Guidelines of Indonesia (PKJI 2014) and queue length calculation using the queuing analysis method. Data have been collected and analysed by making the model relationship using linear regression method. The result showed that there is a positive relationship between the train lengths with the duration of gate closing time. However, the train speed has a negative relationship. Moreover, the length of the train has a positive relationship with the length of the vehicle queue.

Currently the increase in vehicle volume in the cities of Bandung and Jakarta has grown very rapidly. This is accompanied by an increase in the volume of vehicles traveling from Jakarta to Bandung and vice versa. High Speed Train (HST) becoming the government's choice as a form of mass transportation modernization in Indonesia in building inter-city connectivity and regional development. Study or research on willingness to pay (WTP) is needed to find out the prices that are desired by prospective users. The method used in this study are distribution of questionnaires and interviews with stated preference techniques. The result that the highest probability value is in scenario 1 frequency with a probability value of 96.00%. Or it can be interpreted that as many as 96.00% of respondents of Argo Parahyangan train users will use the HST if the facilities offered are the frequency of train departures once an hour. The biggest WTP is in the scenario conditions offered, namely intermodal accessibility connected with the LRT (Light Rail Transit) mode, and also once a hour frequency scenario where the WTP value reaches.

The maintenance of railway in Indonesia is determined by the track quality index (TQI). Analysed of TQI is based on track geometric inspection data. Currently, track geometric inspection uses a Track Geometric Vehicle (TGV) or Track Recorded Vehicle (TRV). The TRV's provide accurate geometry measurements. But, it was expensive to run, may disrupt regular train services during their operation, need for occupation of track limit the number of measurement operations undertaken annually and optical sensors are sensitive to the dirt, found in the railway environment. TRV's data was analysed by statistical function of the standard deviation to determine of TQI. TQI has some disadvantages, for example, it cannot represented the wavelength contents of the geometry defect, which is related to the particular issue in train-track interaction. Therefore, it is necessary to propose effective, efficient and reliable track quality assessment method. This paper will review some irregularity track monitoring methods that were probably used to track monitoring in Indonesia.
