ANSWER:

If the people in the community consider this as traveling, you can shorten and combine. But if this is considered as a suburb and no one considers it traveling, one must not shorten nor combine. 

I would like to ask about Qasr if I am eligible to pray in my situation. My work place from my home is around 100 to 120 KMS far. I travel daily to work in Bus. I start from my place at 5:40 AM and in return I start at 4:00 PM and asr Salah time starts at 3:58 PM. Can I pray Qasr (2+2 at Zuhr and asr time)? Can I pray jama qasr salah (2 + 2 at same time)
