Comparison of Traditional and Green Public Transportation Vehicles in Terms of CO2 Emissions

Abstract

There is a high demand in energy consumption of cities due to growth in population, and more pollution due to high CO2 emissions. Effective methods for increasing energy efficiency include the adoption of green vehicles to the transportation systems. The chapter aims to evaluate traditional public transportation technologies, introduce alternative future green transportation technologies in smart and sustainable cities, and make comparison between traditional and green public transportation systems. Istanbul is chosen to apply a case study to explain the importance of using green transportation ways in terms of CO2 emissions. The results of different transportation modes in different routes are compared. The results found for different scenarios on the routes in this case study ensure that the most eco-friendly options would be the walking, cycling, and public transportation ways for the passengers, although they may not provide the optimal solutions in terms of total duration and distance traveled.
