A VGG-based convolutional model predicts crash severity from Thai highway records for 2011–2023. Categorical features become grayscale images, with class balancing and Bayesian optimisation; evaluation uses F1-score and AUC.
Proceedings of the 14th Asia-Pacific Conference on Transportation and the Environment (APTE 2025), 188–198
A camera-based traffic survey device detects, counts and classifies vehicles into 13 Department of Highways categories. Image processing and machine learning support automated traffic-volume collection.
Proceedings of the 14th Asia-Pacific Conference on Transportation and the Environment (APTE 2025), 116–126
Statistical association measures and a convolutional deep-learning model examine factors linked to fatalities in Thai highway crash records. The study highlights safety equipment, road-user type and lighting conditions.
Proceedings of the 14th Asia-Pacific Conference on Transportation and the Environment (APTE 2025), 127–136
A survey of 234 participants at Chulalongkorn University combines factor analysis and logistic regression to examine how safety awareness relates to recommending rental e-scooter services.
Kasetsart Journal of Social Sciences, 45(1), 235–246
Surveys across five Silor routes in Bangkok compare travel patterns and service perceptions among users and non-users. Statistical classification identified four user groups with different needs and expectations.
Sustainability, 15(6), 5273
Structural equation models compare how service quality, passenger confidence and health measures relate to bus-use intentions in Bangkok and Jakarta during the pandemic.
Sustainability, 14(14), 8482
An online survey of 403 participants in Bangkok and nearby areas was analysed using structural equation modelling. The study examined how technology acceptance and environmental concern relate to battery-electric vehicle purchase intentions and use.
Engineering Journal, 22(3), 109–122
Ordered probabilistic models analyse 483 traveller surveys to study bus and informal-transport use in Phnom Penh. Costs, traveller characteristics, comfort and availability help explain differences in usage frequency.
