I am working with VANETs and need to get some authenticated dataset. Please suggest the ways, I can get the dataset online or offline.
I think there is not exist a real simulator that can simulate the traffic, but you can calibrate any for your case study.
Do you mean real (i.e., observed) data or simulated data? Which kind of data?
Traffic data can only be obtained through field studies. I understand you are talking about road traffic.
Traffic data can be obtained by different surveys/studies in field (I am talking about road traffic)...
Dear @Martin Treiber sir, I mean to get real data if possible for any road, Otherwise please suggest, if it is possible to get the simulated data.
Dear Vinita Jindal,
Your question is too synthetic. From surveys on road you can obtain more data as: numbers of vehicle (splitted data for type, bike, motorbike, cars commercial vehicles etc), gap between these, speed and flows etc.
If you know these data for any one road you can simulate flows, to obtain a large set of data. But you always remember that these data are true as much as your survey: please, specify better what you need.
The NGSIM data sets may help. They are actual vehicle trajectory data for multiple locations (although each is a pretty small area). I used a subset of one data set as input to an NS-2 model some years ago, and other researchers on VANETs have used the data sets. Unfortunately the community website for the project is not working correctly at the moment, so you can't get to the data sets there, BUT two of the data sets, complete with documentation, are available elsewhere:
US 101 - http://gateway.path.berkeley.edu/ngsimdocs/US-101
I-80 - http://gateway.path.berkeley.edu/ngsimdocs/I-80
General project information is available at the community site, which is at http://ngsim-community.org/
The NGSim program developed improved algorithms for traffic simulaton, and to validate the algorithms they captured video data from multiple roadway types and locatons and then used image processing to convert the video data into vehicle trajectories.

Thanks @ Mike Mcgurrin sir. this is very useful link indeed. Thank you very much.
