Title:

Evaluation of Mobile Source Greenhouse Gas Carbon Dioxide Emissions for Assessment of Traffic Management Strategies

Abstract:

In recent years, there has been an increasing interest in investigating the air quality benefits of traffic management strategies in light of challenges associated with global warming and climate change. However, there has not been a systematic effort to study the impact of a specific traffic management strategy on mobile source Greenhouse Gas (GHG) emissions, in particular, carbon dioxide (CO2) emissions. This research is intended to evaluate mobile source CO2 emissions for assessment of traffic management strategies, in which a Portable Emission Measurement System (PEMS) is used to collect vehicle’s real-world emission data, and a Vehicle Specific Power (VSP) based modeling approach is used as the basis for emission estimation. By this approach, three case studies are designed for High Occupancy Vehicle (HOV) lane, traffic signal coordination plan, and Electronic Toll Collection (ETC). In the HOV lane scenario, CO2 emission factors produced by the test vehicle using HOV lane and the corresponding mixed flow lane are compared. In the evaluation of traffic signal coordination, total CO2 emissions produced under the existing coordinated signal timing and the emulated non-coordinated signal timing along the same testing route are compared. In the ETC case study, total CO2 emissions produced by the test vehicle around an ETC station and an MTC station located on the same toll road segment are estimated and compared. The results indicate that HOV lane, well-coordinated signal timing, and ETC are all effective measures to reduce mobile source CO2 emissions, although the level of effectiveness is different for different strategies.
