Currently, the ASEAN Community has opened and this has resulted in the expansion of the road network between member countries, making it more convenient to drive crossing the border. However, the difference in laws relating to the speed limits and their enforcement may result in drivers unknowingly violating the laws in each country, leading to an increased risk of accidents. This research aims to determine the statistical correlation between the traffic accident fatalities, the enforcement of speed limits with the gross national incomes of Thailand and its cross-border countries. Linear and non-linear regression analyses were applied to develop models explaining their correlations at 95% confidence level. The results indicated that those countries with higher efficiency in enforcement on speeding laws and greater gross national income have a lower rate of traffic accident fatalities. The results of this study are useful for responsible agencies to determine the required traffic safety strategies in order to reduce the number of traffic accidents within ASEAN countries.

Tujuan dari tesis ini adalah untuk mengetahui faktor geometrik dan lingkungan jalan apa saja yang diduga memiliki pengaruh yang signifikan sebagai penyebab kecelakaan di berbagai lokasi di kawasan rural Kalimantan dan Sulawesi. Studi kasus ini menggunakan kasus jalan raya lintas Pontianak-Singkawang di Kalimantan Barat, lintas Martapura - Barabai di Kalimantan Selatan, dan lintas Takalar-Bulukumba di Sulawesi Selatan. Survey dilakukan di 3 propinsi yang terbagi dalam 22 blackspot (titik rawan kecelakaan). Variabel yang dievaluasi adalah alinyemen jalan, superelevasi, lebar jalan, lebar bahu jalan, lebar zona bebas/clear zone, kondisi permukaan jalan, keberadaan rambu dan marka jalan. Teknik analisa yang digunakan adalah analisa statistik dengan model multivariat generalized linear model dengan distribusi negatif binomial menggunakan software GLIM4. Hasil penelitian menunjukkan bahwa variabel yang paling dominan terhadap terjadinya kecelakaan adalah lebar jalan, clearzone dan keberadaan rambu lalu lintas. ......The purpose of this thesis was to determine the geometric and the road environment factors thar suspected of having a significant effect as the cause of accidents at various locations in Kalimantan and Sulawesi rural areas. This case study uses the case of the Pontianak- Singkawang route in West Kalimantan, Martapura-Barabai route in South Kalimantan, and Takalar-Bulukumba route in South Sulawesi. Survey conducted in three provinces that are divided into 22 blackspot. The variables evaluated were the road alignment, superelevation, road width, shoulder width, the width of clear zones, road surface conditions, the presence of road signs and road markings. The analysis techniques that use are statistical analysis with a generalized linear model multivariate model with negative binomial distribution using software GLIM 4. The results showed that the most dominant variables to the occurrence of accidents is the width of the road, clearzone and the presence of traffic signs.
