Introduction: Accidents are one of the biggest public health problems in the world. At the same time, most young victims are in good health before the accident. World Health Organization studies indicate that in 2020 road accidents will be one of three of the three leading causes of death globally. Materials and Methods: Due to selecting the inner-city route, this study identified the accident hot zones by the number-accident intensity index method in one year. The table of coefficients proposed by the state of Georgia was used to weigh the severity of the accidents (injuries, deaths, and damages). Results: In this study, six spatial units were identified as hot zones ( 9/1% ), and 19 spatial units were identified as yellow zones ( 28/8% ); as. Finally, 41 spatial units ( 4100 meters from 6600 meters ) were identified as cold zones ( 62/1% ). Conclusion: The most important ways to reduce traffic accidents include the review of traffic signs in terms of the number, size, location, height, and the installation of the speed breaker in the spatial units as hot zones, the construction of an underpass, and the structure of pedestrian bridges with embedding the escalator in some important routs ( hot zones ), developing a comprehensive and long– term training program for improving the driving culture, etc.

A model of engineering geological classification and zoning of the Scorillo Dam site in Romania is proposed to optimise the design of the dam and of the grout curtain. The rock mass was classified into four categories: from 1 (good) to 4 (very poor), according to the rock mass quality (RMQ) at the dam site. Parameters available and used to determine the RMQ were lithology, degree of weathering and fragmentation, rock quality designation (RQD), and modulus of elasticity (E). Based on the study, a new design of the dam, its slopes, and the grout curtain was carried out.
