DEVELOPMENT OF A 24-HOUR TRANSPORTATION NETWORK AND EMISSION MODELLING SYSTEM FOR HALIFAX

Abstract

The objectives of this study is to develop a 24-hour transportation network model for Halifax, to estimate emission by using the modeling system and to evaluate alternate transit infrastructure projects. A regional transportation network model was developed and validated. Emissions from GHG, GHG, CO, NOx, THC, VOC, PM10, and PM2.5 were estimated. Model results reveals that annual per capita GHG emission was found 3.09 ton in 2011 and forecasted 3.41 ton for 2021. The results also suggests that emission polluting power and pollution experienced demonstrates difference for instance, suburban and rural areas experiencing more emission than they generate. Study results suggests that modal shift from auto to transit or active transportation would help to reduce emissions, for example, 3.81% less emission for a 5% shift towards transit. Alternative transit infrastructure evaluation concludes that rail and BRT would decrease auto ridership and emission whereas BRT would reduce travel time.
