Abstract:

The transportation sector is a major contributor to air pollution. Therefore, it is essential to monitor vehicular emissions in order to control air quality. Many researchers showed interest in the Second Strategic Highway Research Program (SHRP 2) Naturalistic Driving Study (NDS) data to conduct safety and driver distraction studies. One major benefit of using such a dataset is that it represents the overall vehicle fleet, driver population, and traffic conditions in the United States. There is potential to utilize this data in modal emission modeling at project level by acquiring second-by-second speed and acceleration to calculate vehicle-specific power, then assign data to different operating mode bins to estimate emissions. The primary focus of this study was to utilize SHRP 2 NDS data to estimate emissions of criteria pollutants for work zones in four-lane divided principal arterials with different configurations. The analysis also considered work zone principal areas and level of congestion. Overall, results showed that the work zone area type and configuration did not have any impact on emissions, although high congestion levels increased emissions, predominantly within the activity area. Further investigations that compared the different bivariate speed and acceleration distributions using the energy statistics showed that work zone configuration and principal area had a significant impact on vehicle operations.
