Research by Zhang et al. (2011) has demonstrated that vehicles tend to emit more pollutants in stop-and-start driving, e.g., when transitioning between free-flow and congested conditions. These pollutants take time to disperse and end up accumulating in the air at traffic lights. This will mean increased exposure to air pollutants for the people living along and near the roadway intersection of Rt. 413 and 213.

Research by Zhang et al. (2011) has demonstrated that vehicles tend to emit more pollutants in stop-and-start driving, e.g., when transitioning between free-flow and congested conditions. These pollutants take time to disperse and end up accumulating in the air at traffic lights. This will mean increased exposure to air pollutants for the people living along and near the roadway intersection of Rt. 413 and 213.

The queueing condition was modeled for the no build and build conditions and it was found that queueing in the PM Peak on PA 413 northbound will decrease, on PA 413 southbound will increase, and on PA 213 it will increase in the build condition due to updated timing and new traffic patterns. The overall intersection traffic volumes and queueing will be similar in the no build and build condition, with no major impacts as a result of the US 1 project.
