Research and statistical figures often conclude that traffic accidents are an iceberg for comprehending the discrepancies of traffic management and entire transportation systems. Figures detailing traffic accidents in Indonesia, as is the case in many other countries, show significantly high numbers and severity levels; these types of totals are also evident in Jakarta, the highest-populated city in the country. Indonesia now has a population of more than 230 million people, and the country’s economic growth has given rise to increases in transportation demand and vehicle ownership. Similar figures are also evident in Jakarta, the capital, which has a population of almost 10 million people. The figures are even higher in the daytime due to commuters from the outlying areas and some supporting cities (i.e., Jabodetabek). We predict that Jakarta may have a population of around 12 million people during the daytime. With a road ratio of only less than 7%, the high vehicle growth rate and poor public transportation contribute to high-density road use. This problematic situation is hard to resolve as more than 90% of the available transportation modes are road-based. Figure 1 shows the numbers of traffic accidents in Indonesia over the last ten years (2004–۲۰۱۳). The table also indicates some classifications of accident severity: fatalities, severe injuries, and light injuries. Although fatalities and severe injuries are much fewer compared to light injuries, their numbers and trends are still high.
