Dear Mr. Wright,
Mobility Budget is measured either in time spent in daily trips using
Marchetti constant or Per capita mobility used by poorer countries with low
ecological footprints like India. Use of Marchetti constant in sustainable
transport is illustrated in Newman, Peter, & Kenworthy, Jeffrey. (2006).
Urban Design to Reduce Automobile Dependence. Opolis, 2(1).
We use per capita mobility and distribute it amongst available modes. Though
no agreed basis exists, distribution is made as 60% PT (Road/rail) and 40%
NMT and private vehicles. With road length of 0.6 m/capita, proportion of
HRT systems of Hong Kong and Tokyo, as per UITP, provide for a capacity of
8000 seat kms/capita/year which works out to roughly 40% of 20000 kms/capita
year mobility planned by them. Current Indian mobility is around 10,000 pkm
which is likely to rise to 13000 pkm/capita/annum by 2020. I presume the ADB
will work on the millennium goals for sustainable development as adopted by
P.s. You might refer to article B : OVERVIEW OF URBANISATION TRENDS IN
CHINA. RECENT PAST TRENDS. by Dr. E.G. Prior who was in Charge of Urban
development of Hong Kong till recently. His strategies may apply to many
countries facing rapid urbanisation like India.
