Instead I prefer to trust good design and human nature (Hans Monderman and shared space). What if you let all road-users use all available road space, but encourage private or commercial drivers to give way when they saw a bus approaching?

The dedicated bus lanes are in the central as you describe: Traffic in India drives on the left side of a road. In the case of a divided highway, one proposal is to run the BRTS in a separate lane (taking the place of the "Fast Lane", i.e. to the right hand edge of the left half of the road. This means that entry and exit from the busses would have to be to and from fresh islands in the road (since doors are on the left side of the bus) or else fresh doors would have to be cut into the bus, so that passengers can board and get off onto a central island..Do take a look. The design is good and will eventually start working but it seems such a waste to execute it so badly as Pune Municipal Corporation is doing. Already people traveling in these BRT buses are experiencing something unique - seeing the buses move faster than other auto vehicles on the road, and that's how it should be.

Please shoot it down (with reasons) if it is impractical for India . Traffic in India drives on the left side of a road. In the case of a divided highway, one proposal is to run the BRTS in a separate lane (taking the place of the "Fast Lane", i.e. to the right hand edge of the left half of the road. This means that entry and exit from the busses would have to be to and from fresh islands in the road (since doors are on the left side of the bus) or else fresh doors would have to be cut into the bus, so that passengers can board and get off onto a central island.. Actually, for reasons of flexibility, and if these are "Long" busses, with centre doors, it seems to me to make sense to strengthen the body and cut doors out on the right side of the bus. Then a single stop or station would exist at each location for both directions. An alternative, which I have not seen mentioned yet, is to run the BRTS busses on the WRONG SIDE OF THE ROAD. That is, busses going north would run in the grade-separated, "Fast lane" of the southbound side of the road. And busses going South would run in the fast lane of the northbound side of the divided highway.  Then one would use the normal doors (on the left side of the bus), thus eliminating any need to strengthen the chassis. Pune experience within days of the start of BRTS makes it clear that with our population density, and general attitude towards discipline in general, Grade-Separation between the normal roadway (of at least 8 inches) and the BRTS lanes, is essential to avoid many, many fatal accidents.  If the BRTS lane is grade-separated, there should be no problem about the BRTS busses running in the opposite direction to the regular stream of traffic. Contra-ideas, anyone?

I take it what concerns you is the (two per stop) conflicts between buses moving in opposite directions? Remember that the buses will be moving slowly as they are about to stop or are just leaving the stop. I don't know offhand what the maximum bus flows are likely to be, but I would not have thought that even in Mumbai there would be more than 120 buses per hour - correct me someone if I'm wrong (I could do a check, but it would take some time). At that level I see no problem with a simple "give way" arrangement (e.g. incoming buses always give way to leaving buses) - you could have traffic signals, but IMO that would be an unnecessary expense.

MMRDA explained to me an ingenious proposal for overcoming this - at the stops the buses would swap sides, crossing the median through a gap immediately before and after the stop. This sounds perfectly feasible to me - the only potential problem I foresee is that the necessary gaps will be used (illegally) by other traffic, or even pedestrians (who get a pretty raw deal in terms of getting across the road). >   That seems really dangerous unless there are electronic safety systems, etc. Am I missing something? - T -- -------------------------------------------- Todd Edelman Director Green Idea Factory Korunn� 72 CZ-10100 Praha 10 Czech Republic ++420 605 915 970 ++420 222 517 832 Skype: toddedelman <A href="mailto:edelman@greenidea.eu">edelman@greenidea.eu</A> <A href="http://www.worldcarfree.net/onthetrain">http://www.worldcarfree.net/onthetrain</A> Green Idea Factory, a member of World Carfree Network</BLOCKQUOTE></DIV></DIV> ............................................................................................................................................................................................
