The seminar topic will present a research on spatial mapping and analysis of traffic accidents risk and severity. GPS was used in recording the accidents' spatial coordinates. The GPS coordinates were registered in GIS to the road network map showing the spatial distribution and frequency of such accidents. Based on such analysis, high accidents locations (HALs) or black spots were identified on the designated maps. The study analyzed as well a number of parameters that may contribute to the existing traffic safety problem at HALs. Geometric and traffic conditions at each HAL, topography (DEM), and climate are among the analyzed variables. The work involved as well transportation system assessment in terms of identifying problems related to traffic flow management (e.g., traffic congestion) and the proposed traffic engineering solutions to enhance traffic safety levels. All of the above analysis was performed on spatially rectified 2D and 3D GIS layers.

He Emergency Evacuation Modeling: A Novel Approach to Layout Designs and Evacuation Procedures”
The development of evacuation models in the last three decades has mainly contributed to the assessment of occupant safety and evacuation procedures in a variety of building designs, under a range of environmental conditions. The effectiveness of such evaluation relies mainly on the models ability to reflect the detailed interactions between the occupant, building design, and environment. The purpose of this study is to present emergency evacuation modeling as a novel approach to layout designs and evacuation procedures. The approach is based on the development of a novel evacuation model that adjusts its outputs to evaluate a range of layout designs. The proposed evacuation model relies on the application of evolutionary computation techniques to assess the means of egress by evolving the location and number of exits needed to ensure occupants safety. The performance of the algorithms varies by occupant behavior. The study suggests that the algorithms have the potential to be implemented in more complex design problems. The study further suggests the need to validate the configurations found by the algorithms by conducting actual evacuation drills.
