This research is an introduction to the topic of simulating vehicles capable of being connected with the infrastructure. The connectivity helps vehicles make better decisions and improves the general traffic flow. It is built around SUMO, an open source traffic simulation software developed by German Aerospace Center (DLR) of traffic studies. Three different scenarios of an urban intersection are simulated. First, an isolated intersection with current traditional traffic is simulated. Then, a camera connected with traffic light is simulated as a form of infrastructure to vehicle connectivity. The camera detects the vehicles in a specific distance from the stop line and adapts the traffic lights in order for the vehicles to pass the intersection safely. Third scenario is where vehicles are given some characteristics of autonomous and connected vehicles sporting less gap between each other, near perfect driving, and faster perception-reaction time. The main goal of our work is to be able to simulate how vehicles with some sort of connectivity impact traffic flow. We used the output from the fixed scenario as our base and compared the numbers we got from the second and third scenarios. We found out that the second scenario yields a better traffic flow with lesser delay and queue length. Moreover, the third scenario had cut more than half of the delay and queue length. In this study, we took an urban intersection and used it as an isolated one. We think if three parameters can have this much effect on traffic flow, having a fully connected and autonomous vehicle will have a larger effect on reducing collisions and congestions. My professor, colleagues and I are planning to do further studies of different intersections and roadways and evaluate its applicability.

The increasing power of computer technologies, the evolution of software en- neering and the advent of the intelligent transport systems has prompted traf c simulation to become one of the most used approaches for traf c analysis in s- port of the design and evaluation of traf c systems. The ability of traf c simulation to emulate the time variability of traf c phenomena makes it a unique tool for capturing the complexity of traf c systems. In recent years, traf c simulation – and namely microscopic traf c simulation – has moved from the academic to the professional world. A wide variety of traf- c simulation software is currently available on the market and it is utilized by thousands of users, consultants, researchers and public agencies. Microscopic traf c simulation based on the emulation of traf c ows from the dynamics of individual vehicles is becoming one the most attractive approaches. However, traf c simulation still lacks a uni ed treatment. Dozens of papers on theory and applications are published in scienti c journals every year. A search of simulation-related papers and workshops through the proceedings of the last annual TRB meetings would support this assertion, as would a review of the minutes from speci cally dedicated meetings such as the International Symposiums on Traf c Simulation (Yokohama, 2002; Lausanne, 2006; Brisbane, 2008) or the International Workshops on Traf c Modeling and Simulation (Tucson, 2001; Barcelona, 2003; Sedona, 2005; Graz 2008). Yet, the only comprehensive treatment of the subject to be found so far is in the user’s manuals of various software products.

This book constitutes the thoroughly refereed proceedings of the First International Conference on Simulation of Urban Mobility, SUMO 2013, held in Berlin, Germany, in May 2013. The 12 revised full papers presented tin this book were carefully selected and reviewed from 22 submissions. The papers are organized in two topical sections: models and technical innovations and applications and surveys.
