After the economic crisis in 1997, motorcycles become a popular transport mode in Indonesian cities.However this condition leads to large number of violation and accident rate. This study tried to discuss howthis problem started and what possible measure can be taken to solve the problems, mainly based on literaturereview. The traffic data used were compiled from the data provided by PT Pamintori Cipta. Interview surveywas conducted to find people perception of motorcycles issues. The conclusion suggests that there is a needof further comprehensive study to find out what condition that makes motorcyclists voluntary return to usepublic transport and social engineering and intensive training program should be implemented for youngergeneration to improve traffic condition in Jakarta.Keywords : motorcycle violation, traffic safety, and public transport.

In most traffic projects, speed survey is required. If the speed survey uses detector, all data might be obtained. Otherwise a sampling strategy needs to be introduced. To ensure the collection of representative sample of speeds there were several sampling options, e.g. collecting sample every regular interval. In this paper three regular intervals were tested, i.e. 30 seconds, 1 minute and 2 minutes 30 seconds. Travel time data was collected in morning, mid day, and afternoon periods in a two-lanes two-ways underpass in Jakarta. Travel speeds were calculated by dividing light vehicle travel times with the underpass length. Space mean speeds were calculated as a light vehicle travel mean speeds/ 5 minutes. The observation of each light vehicle travel times (to get each light vehicle travel speeds) was conducted for the first 15 minutes of three observation periods. More frequent speed sample collection provides higher accuracy.Keywords: space mean speed, sampling strategy, regular interval sampling

A comprehensive knowledge regarding vehicle distribution can be utilized to adjust vehicle distribution coefficient (C) on the Manual of Indonesian Flexible Pavement Design (SKBI-2.3.26.1987). This paper discusses the effect of city characteristics, lane configuration, and flow level on vehicle distribution in urban road lanes. Three cities were observed, i.e. Mataram, Bandung, and Surabaya. Ten road links were observedwhich consist of six 4 lanes-2 ways and four 6 lanes-2 ways divided roads. Surveys were carried out for 24 hours of a normal working day. Traffic counts were grouped every 15 minutes per direction, per lane for 3 vehicle types. i.e. light vehicle, heavy vehicle, and motorcycle. T-test of mean differences was used as a technique for analysis. The results show that the design lane was the most right lane and the values of C in Mataram, Bandung, and Surabaya were higher than those on the Manual.Keywords: vehicle distribution coeeficient, flexible pavement design

In Indonesian cities, usually a car owner also own a motorcycle to avoid congestion. This cause many problem such as unskilled rider, traffic violation, aggressive behaviour etc. Instruments to assess motorcycle rider behaviour were developed in England, Iran, Turkey, China and Australia. Putranto and Anjaya (2014) propose Indonesian Motorcycle Rider Behaviour Questionnaire (MRBQ) as MRBQ was prove to be sensitive to local culture and social system. This paper is further development of Indonesian MRBQ. Previously the instrument was prepared without strong theoritical basis. In this present paper the instrument was adjustment of Persian MRBQ. After an FGD with experts in motorcycle rider behaviour only 42 items from 48 items in Persian MRBQ were used in in this study. All valid and reliable items were anlysed to compare wheter there are different behaviour between different gender, age, whealth level, job, ethnicity, etc. Respondents were lecturers and employees of Tarumanagara University.
