A traffic accident is an unexpected and inadvertent road event involving a vehicle with or without other road users that results in human injuries and possibly property damage. This study identifies and analyses the characteristics of Indonesian and Malaysian road traffic incidents. The method used was the identification of crash data coordinates and the Equivalent Accident Number (EAN) score per road segment. Accident characteristics are based on the type of road traffic accident, and collision is the most common type of accident. Speed data of two vehicles, cars and motorcycles, was collected through the test driver method by using the same vehicles for cars and motorcycles and following their normal driving habits. From the analysis results, some factors causing accidents on the Bekasi Narogong Road Section are the lack of traffic signs, road surface conditions, and lack of clear road markings. While on the FT050 Johor federal road, every kilometre per segment and along the segment, motorcycles are faster than cars in terms of speed.

In Indonesia, the basis for implementing road safety consists of five pillars which are compiled in the General National Road Safety Plan (RUNK). One of the pillars proclaimed is the behavior of safe road users. This aims as an effort to reduce traffic accidents because road users are the biggest factor in road accidents related to user behavior. The cases of road traffic accidents in Indonesia are dominated by motorcyclists, especially Jakarta, which is one of the cities with a fairly high rate of motorcycle accidents. Because the behavior of road users is closely related to traffic accidents, and also motorcyclists are the users who are involved in the highest traffic accidents, this study explains the factors that determine the safety behavior of motorcyclists in Jakarta. The application of the Theory of Planned Behavior (TPB) is used as a basis for finding the factors that may determine the behavior of the motorcyclist. Furthermore, the research approach used in this study is quantitative with primary data in the form of a closed questionnaire instrument from 230 respondents who ride motorcycles in Jakarta. The data analysis technique used is the Structural Equation Modeling (SEM) approach using the AMOS 22.00 program as a tool in determining the determinants of driver safety behavior. The results of the analysis show that the most dominant direct predictor in determining the safety behavior of motorcyclists in Jakarta is the intention to behave safely. While the indirect factor that determines is the attitude of the driver. The results of the analysis also show that the age of the driver has a significant influence on safety behavior.

One of the negative impacts of transportation problems is congestion. Traffic congestion in urban areas is gradually becoming an important social and economic problem that needs to be addressed. Tangerang City is one of the supporting cities for the Jakarta metropolitan area as well as an area with a significant increase in population and vehicles, resulting in an increase in the number of people's movements or mobility in order to meet the needs of life. Meanwhile, the length of roads in Tangerang City during 2018-2019 did not increase and it is possible that there will be an imbalance between movement and available road capacity or minimal accessibility. The research approach used is quantitative with primary data sources obtained from closed questionnaire instruments from 180 road user respondents at the TangCity Mall intersection, Tangerang City. Analysis of the data used is a structural equation model with the AMOS 22.00 program to determine the factors that influence the impact of congestion. The results of the analysis show that the factors that most influence the impact of congestion are decreased concentration and loss of energy during traffic jams, which are more common in men who are married at the age of over 35 years, with a diploma level of education, as well as the type of work as a Civil Servant.

The presence of the electric rail train (KRL) on the Yogyakarta-Surakarta route expands the list of public transportation modes available to residents of Yogyakarta, Surakarta, and surrounding areas. The Yogyakarta-Surakarta route was previously served by one of the road-based transportation, namely Bus, which was widely used but was abandoned by its users due to a variety of factors. The presence of various alternative modes of transportation today, combined with the Covid-19 pandemic, allows users of public transportation services, particularly the Yogyakarta-Surakarta route, to freely make their choices. Data was gathered through direct interviews and online questionnaires distributed using Google forms. Multiple linear regression and binary logit nisbah were used in the data analysis, and the results were obtained using software, specifically Microsoft Excel and Statistical Product and Service Solutions (SPSS). The Study by binary logit results show that lowering the CBUS (Bus fee) by 1,58 times the unit of money from the CKRL (KRL fee) to Rp7.595/trip from the original Rp12.000/trip will increase bus users by 30%. If TBUS (bus time) is accelerated by 1,81 times the unit time from TKRL (KRL time) to 1 hour and 23 minutes/trip from the original 2 hours and 12 minutes, bus users increase by 50%. Bus users will increase by 70% while KRL users will decrease by 30%, so the number of FBUS (bus frequency) must be increased to 16 times/day from the original 10 times/day by 1,69 times FKRL (KRL frequency).
