Bangalore's traffic mess
The current strategy
Widen roads to keep pace with increasing traffic
Traffic population will rise 90 % between 2005 and 2010.
Road space needs to double every 5 years.
Bangalore 2015 ?
Road widening to keep pace with vehicle population has never worked anywhere worldwide.
Traffic simply imcreases to occupy the increased road space. Congestion remains, commute time, pollution and accidents increase.

Our present strategy - dog chasing its own tail
Road space will never catch up with vehicle population.
Reduce traffic population
Replace private transport with public transport.
This is THE BIGGEST solution, and the only one that will work in the long term.
The mode of public transport that is cheapest, and can be implemented in the shortest time, is the bus.
During rush hour (when people are commuting to or from work),
Each bike carries 1 person
Each car carries 1 person
Each bus carries 75 people
There are 150 vehicles on this flyover.
These are carrying 150 people during rush hour.
There are 75 vehicles between each pair of red lines, carrying 75 people (because there is only 1 person in each car or bike)
If we get each group of 75 people out of their private vehicles and into buses,
This is what happens.
Road space used by a person in a bus is:
3 % of that in a car
5 % of that on a 2-wheeler
The logic already works in Bangalore
32 Lakh people in private vehicles occupy this much road space
38 Lakh people in 5000 buses occupy this much road space (0.5 %)
BMTC has 5000 buses, carries 38 Lakh people every day.
0.2 % of vehicle population carries 50 % of the human population.
Improved bus system with 7000 more buses : Rs. 2000 Cr.
Expenditure on mix of various classes of buses + improved shelters, signage, etc.
- Ordinary bus costs Rs. 12 Lakh, Suvarna (air suspension, no AC) : Rs. 16 Lakh
- Marco Polo : Rs. 55 Lakh
Can be done in 1-2 years.
Road widening for planned 400 km. : Rs. 4000 Cr.
Metro 33 km. to carry 5 % of Bangalore's population : Rs. 7000 Cr.
Metro 350 km. for whole of Bangalore : Rs. 100,000 Cr.
Assumes underground, at Rs. 300 Cr. Per km.
Will take 50-60 years to build.
London has 400 km. with 270 stations. Its size and population are same as Bangalore's.
This is no great new discovery
Traffic congestion in hundreds of cities worldwide has been solved by bus-based public transport systems.
Hundreds more are in the process of implementing bus-based systems.
Improve traffic speed
Congestion is mainly caused by interesctions. In this picture, note the congestion at the intersection and the sparse traffic at the back.
Can increase traffic speed by 10 - 25 % on arterial roads.
Eliminate traffic intersections and signals and can increase traffic speed by 25 -50 %.
No parking on roads
Parking occupies 25 % of the space on most roads. Basement parking in buildings (required by law) is misused for commercial purposes, due to lax law enforcement.
Road surface quality
Makes a big difference to traffic speed.
A vehicles's speed drops to 5 kmph. when approaching a pothole or a rough surface.
Mapunity Bangalore Traffic Information System
First use existing road space to maximum efficiency.
Then think of increasing road space.
We are however doing the reverse. Our road space usage efficiency is abysmal.
Without destroying Bangalore
These solutions can achieve this
No. of vehicles by 75 %
Commute timeby 30 %
Pollutionby 80 %
Govt. expenditure on roadsby 90 %
Increase expenditure on
Rest of Karnataka
