• Many public policies and private decisions require weighing multiple objectives and contemplating trade‐offs (Saaty, 2008)
• Decision makers frequently consider several criteria beyond quantified benefits when formulating policies.
• Analytical Hierarchy Process (AHP) is used to screen policies and identify priorities before quantifying benefits.
• AHP involves pairwise comparisons and expert judgements to evaluate intangibles in relative terms and determine priorities.

Running
Stop
Apply Stepwise Speed Function (SSF): average speed of each running period (Kanari et al., 2012) Re‐calculate Vehicle Specific Power (VSP) bin distribution Eco‐driving ratio of 100% for Bandung city
Eco‐driving: a new driving culture (smarter) that makes best use of advanced vehicle technologies for and more fuel‐efficient driving
S2: Pedestrian and non‐motorized program• Non‐motorized program for government officer Focus on Government Officers living in Urban Areas Shifting from private vehicle to bicycle or walking Assumption: 4,600 unit of PC and 12,800 unit of MC Recalculated on Total VKT
• Car free night (CFN) and car free day (CFD) Visitors use non‐motorized transport means (walking and cycling) 8 events in a month for CFN & CFD (96 events in a year) Average number of visitors reported in media (15,000 people for
both). It was assumed approximately : PC=1,300 unit, MC=5,500 unit
Recalculate total reduction of VKT (km/year) for PC and MC due to these events
17
S3: Paratransit revitalization program• Local policy: Paratransit’s Vehicle age should be < 7 years & 3 years transition (10 years)
• Paratransit with age for more than 10 years will be scrappaged Technology distribution change (fleet file) Conduct IVE re‐simulation new composite emission factors

Concluding Thoughts• Contribution on Baseline of CO2 emission in Bandung city: Private cars: 51.72% Motorcycle: 29.02 % Public Transport Modes (Bus, Paratransit and Taxi): 19.26%.
• The reduction of CO2 emission through three selected priority policies: (a) Eco driving: 10.54 %; (b) revitalization of paratransit: 1.34% (c) Pedestrian and non‐motorized transport program: 1.04%
• On the Paratransit:(i) Eco Driving and Revitalization: reduce 52.89% of total emission. (ii) However, it is only about 1.67% of total emission of transport sector.
• Therefore, in the future, priority program should be more focus on Private Vehicle (Eco‐Driving & Pedestrianization). It will give more significant impact on CO2 emission reduction in Bandung City.
