This study introduces the areawide road safety improvement program, which was developed to overcome the weak points of conventional black spot improvement programs. The latter has been criticized in terms of that it can cause the problem of accident migration and that it prevents from identifying causes of road accident in the comprehensive scope. On the other hand, the areawide road safety improvement program can allow us to find the route or areas that have quite a number of road accidents with the common causes. Therefore, we can take countermeasures effectively in a different framework in this approach. This study explains in detail about the concept, procedures, and effects of areawide road safety improvement programs including the example. This study may contribute to bringing a new framework of road safety improvement program in Korea.

The flat dilatometer test (DMT) is a geotechnical tool to estimate in-situ properties of various types of ground materials. The undrained shear strength is known to be the most reliable and useful parameter obtained by DMT. However, the existing relationships which were established for other local deposits depend on the regional geotechnical characteristics. In addition, the flat dilatometer test results have been interpreted using three intermediate indices - material index $(I_D)$, horizontal stress index $(K_D)$, and dilatometer modulus (E$_{D}$) and the undrained shear strength has been estimated merely using the horizontal stress index $(K_D)$. In this paper, the applicability of the flat dilatometer to Korean soft clay deposit has been investigated. Then an artificial neural network was developed to evaluate the undrained shear strength by DMT and the ANN, based on the $p_0, p_1, p_2, {\sigma '}_v$ and porewater pressure. The ANN which adopts the back-propagation algorithm was trained based on the DMT data obtained from Korean soft clay. To investigate the feasibility of ANN model, the prediction results obtained from data which were not used to train the ANN and those obtained from existing relationships were compared.
