The UCF Driving simulator was used to test a proposed pavement-marking design. This marking is placed upstream of signalized intersections to assist the motorists with advance warning concerning the occurrence of the clearance interval. The results of the experiment have indicated promising results for intersection safety. Firstly compared to regular intersections, the pavement marking could results in a 74.3 percent reduction in red-light running. In comparison, the pavement marking reduced the number of occurrences where drivers chose to continue through an intersection when it was not safe to proceed compared to the without marking, and this result is correlated to less red-light running rate with marking. According to survey results, all of the tested subjects gave a positive evaluation of the pavement-marking countermeasure and nobody felt confused or uncomfortable when they made stop-go decision. In comparison between scenarios without marking and with marking, there is no significant difference found in the operation speeds and drivers brake response time, which proved that the marking has no significantly negative effect on driver behaviors at intersections. The UCF driving simulator was also used to test vertical and horizontal visibility blockages. For the horizontal visibility blockage, two sub-scenarios were designed, and the results confirmed that LTVs contribute to the increase of rear-end collisions on the roads. This finding may be contributed to the fact that LTVs cause horizontal visibility blockage. Indeed, the results showed that passenger car drivers behind LTVs are prone to speed more and to keep a small gap with the latter relatively to driving behind passenger cars. From the survey analysis 65% of the subjects said that they drive close to LTVs in real life. As for the vertical visibility blockage, three sub-scenarios were designed in the driving simulator, and the results confirmed that LSVs increase the rate of red light running significantly due to vertical visibility blockage of the traffic signal pole. However, the behavior of the drivers when they drive behind LSVs is not different then their behavior when drive behind passenger cars. The suggested addition of the traffic signal pole on the side of the road significantly decreased the red light running rate. Moreover, 65% of the subjects driving behind an LSV with the proposed additional traffic signal pole said that the traffic signal pole is effective and that it should be applied to real world.

This manual presents recommended testing procedures for making determinations of the soil properties to be used in the design of civil works projects. It is not intended to be a text book on soils testing or to supplant the judgment of design engineers in specifying procedures to satisfy the requirements of a particular project, although it has been used in basic soil mechanics courses. Test procedures included are Water Content, Unit Weights, Void Ratio, Porosity and Degree Of Saturation, Liquid and Plastic Limits, Shrinkage Limit Test, Grain-size Analysis, Compaction Tests, Permeability Tests, Consolidation Test, Swell and Swell Pressure Tests. Drained Direct Shear Test, Triaxial Compression Tests, Determination of Critical Void Ratio, Unconfined Compression Test, Modified Providence Vibrated Density Test, and Pinhole Erosion Test for Identification of Dispersive Clays.

Despite occupying a central role and frequently being used in the study of international politics, the concept of the "event" remains in many ways unchallenged and unexplored. By combining the philosophy of Gilles Deleuze and his concept of the event with the example of 9/11 as an historical event, this book problematises the role and meaning of "events" in international politics. Lundborg seeks to demonstrate how the historical event can be analysed as a practice of inscribing temporal borders and distinctions. Specifically he shows how this practice relies upon an ongoing process of capturing various movements – of thought, sense, experience and becoming. However the book also demonstrates how these same movements express a life and reality that elude complete capture, highlighting the potential for alternative encounters with the event, encounters that constantly threaten to undermine the limits and imaginary completeness of the historical event. This book offers an exciting new way of thinking about the politics of encountering events, arguing that at the heart of such encounters there are always elements of uncertainty and contingency that cannot be fully resolved or fixed. It will be of great interest to students and scholars of international relations, cultural studies and history.

A suggested solution for the vertical visibility blockage of the traffic light problem that consisted of adding a traffic signal pole on the right side of the road was also designed in the driving simulator.
