Been living in Vizag for the past 3–4 years.
One thing that I never saw all these years: Traffic Jam.

BRTS Road
Beach Road
Dronamraju Circle, Siripuram
RK Beach Road-1

RK Beach Road-2
The roads in the city are quite wide. The buses being operated by Andhra Pradesh State Road Transportation Corporation (APSRTC) are available round the clock. Auto-rickshaws are also available.
You will get to visit almost all the places in the city via the buses at a very minimal cost, something around (Rs.1/km). Share-auto fares are not much either. So, the people in the city prefer public transportation to their own privately owned vehicles. On top of that, Andhra Police is very vigilant and strict.
Hence, no traffic problem.
That, for me, is the best thing about Vizag.
Thank you for scrolling down. May God bless you.
Edit 1: NAD Junction is probably one of the few places in Vizag where you can see heavy traffic. Yet, it is not like Chennai or Mumbai. My friends from Delhi reckon Vizag is much better during the rush hours. But I believe, a flyover is planned to be constructed near the NAD Junction. Vizag Metro is coming up too.
