In our project, we did traffic study for around 8 roads and we want to extrapolate that data to remaining roads(approx 50 roads). Is it possible to extrapolate data among line features ? In this process what are the attributes we have to consider for extrapolating ?

I think you can assign the values from line features to raster map, and use the interpolation tool in ArcGIS to interpolate the other values in raster map. Then you can extrac value to line feature to the other roads. This is just my thought and I hope this may be helpful for your research.
I think your question is much to broad. What do you want to extrapolate (known car counts at some position from 8 lines onto 50 unknowns, or individual cars, or from the timestamp of measure onto some timespan)? Do you have a road network (connected lines), and do you expect the traffic to flow in this network? Shall different road designations have influence on the traffic? Are there traffic sources and sinks? And so on. In my opinion the more dynamic your process is, the less appropriate are out-of-the-box tools of GIS Software, and ist up to you to develope an algorithm or algorithmic approach to solve the problem.
Hi neumann, we just have the car counts for 8 roads and we want to extrapolate them to unknown roads(at least 50 roads) by considering the population (not by distance) as a decision factor. For this work, I have the road network of study area with different designations(eg: Highways, village roads, trunk roads etc.,). Actually, this study is focused on vehicular emissions and I am quite new to this field so, I don`t know whether to consider traffic influence(sources and sinks) or not. Can you please suggest me any papers or correct method to progress further ?
