A Petrinet Realization of an Urban Traffic System
نویسندگان
چکیده
The requirements of system reflect the needs of the customer. Specification of requirements at different levels of abstractions is therefore an important part of system design. Formalism in part of system design is necessary to avoid ambiguity and provide precision. Petrinet is a design tool which has proven to be very promising in this aspect. This paper deals with the application of petrinet in control of pedestrian signals in conjunction with vehicle signals in an urban traffic system. The petrinet realization is followed by defining some constraints which is indispensable in enforcing safety with regard to pedestrians as well as vehicles involved in the traffic system.

This paper makes an intensive study of the realizations and related key technologies in the 3D urban traffic simulation system. First, the system can quickly edit the scenes of the 3D urban, including buildings, roads, etc. It describes the roads using the graph structure, then, the constrained Delaunay algorithm is applied to reconstruct the mesh of the road and terrain. The most important, th...
متن کاملA neuro-fuzzy approach to vehicular traffic flow prediction for a metropolis in a developing country
Short-term prediction of traffic flow is central to alleviating congestion and controlling the negative impacts of environmental pollution resulting from vehicle emissions on both inter- and intra-urban highways. The strong need to monitor and control congestion time and costs for metropolis in developing countries has therefore motivated the current study. This paper establishes the applicatio...
