Questions tagged [traffic-simulation]

Traffic simulation are an approximate imitation of traffic flow behavior on any road network.

The components or features that are part of traffic simulations are i) Traffic behavior (homogeneous or heterogeneous), ii) traffic flow models (microscopic, macroscopic or mesoscopic), iii) traffic models (such as car following, lane changing) and iv) system (discrete or continuous).

How to get the curve radius in a traffic simulation?

I am just about to implement a traffic simulation. For the road model, I use data from OpenStreetMap. This means that a road consists of several sections, which are strung together. Of those sections start and end points are known. The vehicle moves…

NS2, packets larger than 100 byte are dropped on 802.15.4

I have a simple 802.15.4 simulation program (2 nodes, CBR traffic). If the size of CBR packets are less than 100, the packets are delivered without problem but as soon as you increase the packet size all packets are dropped. I guess it is because…
