The purpose of this paper is to study the analytical hierarchy process (AHP) based on assessment of sustainability indicators for public transportation system including pedestrians and feeder services in developing country.

A hybrid approach based on the AHP is considered for assessment of the sustainability of public transportation system including pedestrians and feeder services. Sustainability related indicators for public transportation system (namely for metro, bus and feeder bus) and pedestrians based on past data were reviewed and subsequently, more important indicators catering needs of developing country have been added to achieve significant sustainability score and a total of 17 indicators were selected for assessment of comprehensive sustainability (seven indicators under economic, six under social and four under environmental categories).

For quantifying the assessment, specific user interview surveys are performed in south Delhi region and accordingly perception of user and transportation-related operational characteristics of the public transport system were also collected. Preliminary result shows air pollution in environmental category, public health in social category and productivity in economic category is most influential parameters in developing country.

AHP method is applied for rating the criteria and setting out the priority of designed sustainable indicators. Subsequently sustainable mitigation measures and scenarios for the study area can be evaluated utilizing developed comprehensive sustainability indicator for public transportation system including pedestrian and feeder services available in developing country.

The purpose of this paper is to estimate combined exposure factor (CEF) due to impact of different transport-related environmental pollutants, air quality and noise level in Delhi city.

The Estimation of CEF takes into account the potential relative uptake of each pollutant (CO, NO, NO₂, O₃, SO₂, PM10 and PM_2.5) by the boarding and alighting of commuters at Public Transport facility and using motorcycle. With the help of CRRI mobile air pollution monitoring laboratory and previous CRRI reports.

Combined exposure to environmental pollutants is determined based on the taking weighting factor of pollutant stressor. Results shows average stressor for CO, NO, NO₂, SO₂, PM_2.5 and noise were 2.79 mg/m3, 331.83, 210.25, 16.70, 241.3883 µg/m3, and 72.5 dB(A), respectively. Similarly for motorcyclist, results shows average stressor for CO, NO, NO₂, SO₂, PM_2.5 and noise were 5.1 mg/m3, 483, 398, 19.3, 295 µg/m3, and 82.7 dB(A), respectively. The results show higher exposure value for motorcyclist.

Knowledge of exposure factor due to air and noise pollutant for bus commuter in sitting and standing and motorcyclist is not known for Delhi city.
