Describe the main
solutions implemented for mitigating pollution in your town or in your country:
local air pollution: Thailand’s national truck
fleet is younger than many neighbors’, with half under 10 years old and about
25% under 5 years old. Older and generally less efficient trucks are more
prevalent outside Bangkok – about one-third of the national fleet is over 16
years old as of 2010. CNG is available in some areas, and as of 2011, an
estimated one-third of the fleet had been repurposed or bought new to use the fuel.
CNG infrastructure is less common outside Bangkok though.
and consumer awareness: Thailand’s so-called
‘Q-Mark certification’ for transport operators sets standards for trucking
service quality, including some requirements regarding waste management,
vehicle maintenance and fuel consumption. This can also contribute to reducing
air pollution. Also the author has observed on-road inspection of trucks
(without prior information), i.e. checking the exhaust emissions of heavy and
light duty commercial vehicle trucks both
during daytime and nighttime.
Are the solutions described in this course
suited for your city and why?
measures taken so far are not enough to considerable curb air pollution
stemming from the logistics sector. First, bribery may be a challenge when it
comes to on-road inspection of freight vehicles. Second, the CNG programme does
not apply for all vehicles, and the owner-operators might not even be aware of
the programme. More information and awareness raising is needed.
Can you imagine other solutions for your
Based on the course material of
unit 3 and also 4 and the publication’Urban freight transport policy and
planning by Visser, van Binsbergen and Nemoto (1999), the following
options could be applied in Bangkok’s city logistic system in order to reduce
could be nominated for use by trucks, such as truck routes designated only for
specific classes of vehicles – less stop and go, idling = less air pollution
spatial concentrations of transport generating or attracting activities near
freight transport facilities – avoidance of trips, avoidance of air pollution
transfer points at borders of urban areas within Bangkok, providing transport
optimization and limiting the number of truck movements in urban areas =
reducing and possibly even avoiding air pollution, as trips are combines, and
possible also avoidance of empty hauling.
