Results show that there are 77% of private vehicle users who are willing to shift to public transportation if the facilities of these modes are significantly improved. The reduction of CO, NOx, and SO2 every year reach up to 385,264.894 tons of CO/year; 12,292.303 tons NOx/year, and 365.689 tons SO …
