- 5. Including the concepts of: adaptability and monitoring Intuitive representation of the road infrastructure Proposed solution SYNASC 2010 25 September 2010
- 6. Java - architecture neutrality - portability, flexibility, modularity - reuse of code Qt - graphical user interface - intuitive API - easy communication between components and the core of the application PostgreSQL - data are managed in a PostgreSQL relational database Used technologies SYNASC 2010 25 September 2010

- 8. OSM ( O pen S treet M ap) - covers all the European road network and a big part of national roads (~90%) - the maps can be imported both direct from the web both from the local machine Used formats (I) - OSM SYNASC 2010 25 September 2010
- 9. SUMO (S imulation Of U rban Mo bility ) - employed at configuring the simulator - XMLs (road elements) are generated by using TME and sumo.exe - combines the physical level with the logical level of the application Used formats (II) - SUMO SYNASC 2010 25 September 2010
- 10. Important modules – Editing routes and scenarios configure navigating scenarios can be configured parameters specify road start and end edges or similar areas ItemArea SYNASC 2010 25 September 2010
- 11. Implemented in the package editor.tls - Traffic light = node with special proprieties and methods - The default logic ( red / yellow / green intervals) can be modified from: Important modules – Traffic light logic SYNASC 2010 dialog window 25 September 2010
- 12. Traffic diversification by configuring physical attributes and behavioral attributes Important modules – Vehicles editing SYNASC 2010 25 September 2010
- 13. Highlighting the statistical data on the map Coloring the street edges with specific set of colors ( red - high values , green - normal values ) regarding: - the density of cars - average/maximum speed - number of stoppings - degree of occupancy (%) The final viewing of data (I) - On Map SYNASC 2010 25 September 2010
- 14. - graphic by points - graphic by time intervals The final viewing of data (II) – by Charts SYNASC 2010 25 September 2010
- 15. The advantages of dynamic logic for the traffic lights - maintaining a fluent traffic even in the cases with high traffic fluctuations (first hours in the morning, lunch, input/output arteries in the city) or unexpected ones (unfavorable weather conditions, accidents) - static vs. dynamic approach System evaluation SYNASC 2010 25 September 2010
- 16. Our application ( TME ) offers: - a scalable and flexible model for future developments - the possibility of manipulating extensive road infrastructures - an intuitive environment and with control facilities on scenarios - statistical data with impact for selecting the areas with traffic problems Future work: - taking into account pedestrian traffic - including of a system based on recommendation - implementing of a module for mobile and wireless devices, PDA Conclusions SYNASC 2010 25 September 2010

Editor's Notes
- #13: Allows the traffic diversification by configuring the physical attributes (name, acceleration, deceleration, maximum speed, color) and at the same time behavioral attributes (sigma parameter)
- #17: Future work: - taking into account pedestrian traffic - including of a system based on recommendation to offer the drivers suggestion regarding the best route - implementing of a module for mobile and wireless devices, PDA
