Every query has an answer if you refer to the last few pages for all the queries but still I will make these points again:
Essentially for a distance of 850Kms the time taken to cover the stretch depends on a lot of factors and it should and cannot be looked at only in terms of clocking the best times (12,13 or even less hours!).
A sedate 90-100kmph can certainly help in doing it in 12-13 hours but the No. the drivers (Single or alone), Co-passengers, breaks can also be reasons that will impact the timings. So here is what I would still mention depending from where you start:
All my drives so far with speeds between 90-100kmph have ensured that I somehow and always end up doing it in 12/12.5 hours with ample breaks. The best so far has been 10-45 hours through the night, again with the same speeds but way too less traffic due to new years' eve (31 Dec night) and I guess even the truckers were busy guzzling
.
Bangalore - Pune:
Depending on where you stay in Bangalore, it will decide the time you will take to reach the first toll gate at Nelemangala.
6AM "definitely" cannot be a good time to start from Bangalore due to the following reasons:
- Traffic would've started to build up and this will add to the time taken to reach Nelemangala.
- You will hit Tumkur around 7/7-30am and again there will be local traffic to navigate through.
- The Tumkur - Chitradurga stretch will be a breeze yet one needs to cautious to the early morning traffic in wrong direction (Especially the tractor-trailers, 2 wheeler goods carriers which you will encounter without expectation from any puncture in the median.
- Passing Chitradurga & Davanagere will take just about a little longer than usual around 9/10am due to private and govt buses making stops to ferry passengers.
- Ranibennur town will be a bitter experience around 11am for all the reasons mentioned earlier in this thread.
- It is MORE LIKELY that the railway gates wont be lucky for you around 11-15/11-45 and the wait will add to the timings.
If anyone has started at 6am and felt there were no major jams or bottlenecks, then starting at 4am will be "much better" when compared.
So far I've done Bangalore-Pune- Bangalore at least 10 times in 8 months and if you read my personal experiences, it makes a lot of sense to start as early as 4/4-30am. By doing this, not only you will pass all the major bottlenecks with ease but also manage to pass Ranibennur town & the railway gates without stopping. You will soon be able to realise yourself that by merely doing a sedate 80-90kmph you would've averaged almost 70kmph and passed all the bottlenecks with ease and the rest of the roads from Bankapura onwards will be a breeze. A totally fatigue free ride in that case!
Have mentioned this already but the Kolhapur - Pune stretch during any time of the day (of course barring nights) is a circus due to village/town traffic. Having one of the highest 2 wheeler densities in India, Maharastra will greet you with so many 2 wheelers on the highway which will somehow force you to take on the fast lane most of the times. Extra cautious is what the driver will have to be all the way till Pune but nevertheless the drive can be enjoyed with sedate speeds rather than panic and hard braking on this stretch when doing 100kmph and beyond.
Toll booths in Maharsatra too will usually have a beeline of vehicles almost whole through the day (If you compare them with any toll booth in Karnataka on NH4) and starting from Kolhapur exit (Kini) till last toll Before the Pune Bypass (4 toll gates in all), even in the worst case if it meant waiting for 10 minutes at each gate post noon & evenings , it becomes a considerable fraction!
To sum it up, start at 4/4-30am and have a hasslefree ride all the way till Kagal with breakfast and quick tea breaks. Lunch can happen in Kolhapur around 1/1-30 and from here it will take a good 2.5 to 3 hours to reach Pune (and further depending on where you stay in Pune).
Pune - Bangalore:
For the reasons mentioned above, look at starting from here at 4/4-30 am and you will be in Davanagere in 9/9.5 hours. You can plan breakfast in Belgaum and lunch in Davanagere (Genysys is a good resort with decent restaurant and falls on the bypass itself saving your time).
Chitradurga till Tumkur post lunch should be better off than morning with lesser local traffic. Nelemangala till NICE can have thinner traffic around 4-30/5-00pm (Now that trucks are forced to take the NICE I better mention this as the final destination in Bangalore as the rest depends on the infamous traffic snarls).
Hence, if you look at these, not all major bottlenecks can be avoided but passing one early during the day makes the driver happy & Jolly and energy preserved can be used to tackle the last leg on both directions.
Speeds
Many would say that a good car can manage 3 digit speeds and will save much time but a drive for 850kms is not a rally in a closed circuit and as a driver you need to drive with total responsibilty and irrespective of ABS or other loaded stuff in your car, you certainly wont like Panic and Hard braking at high speeds and still realise that the guy doing 90kmph whom you overtook few minutes back is always next to you at every toll both. No achievement this is!!
A driver will enjoy the adrenalin and fancy 3 digit speeds but for how long since we are talking about doing 850kms in a single stretch.
Night Driving
Attempt this only if you are aware of the roads, medians, diversions and other major characteristics and have done this at least 3-4 times during the day. Under normal day/evening driving, Kolhapur - Pune (or back) is a good 3 hours but in the night it is merely 2.5 hours at a constant speed of 90-100kmph with an almost zero braking & gear changes (except toll booths).
My Dad has always been my co-passenger during all my drives and he never thinks twice when we drive through the night only since we've done it with ease after doing considerable trips over the daylight.
For night driving, refer my earlier posts on good timings to avoid major bottlenecks, information on 24/7 fuel stations and driving habits.
(the last 5-8 pages should give you enough of the latest information on all your queries)
Volvos
You wont have issues passing them in the evenings or night and they will usually give way when signalled to overtake. For them too, it is a daily Pune/Mumbai-Bangalore drive and wont indulge in drag racing with you
. At nights, "Everyone" becomes a good driver and it is a horn-free drive and you will be given right to overtake as per the actual Indian driving law from the right hand side by 95% of the traffic.
