Abstract:

This paper describes a recent study, which was conducted to assess the aggregated impact of the M-Tag electronic toll collection system deployment at three major toll plazas in the Baltimore Metropolitan Area. The study focused on the reduction in mobile emissions including hydrocarbon, carbon monoxide, and nitrogen oxide, for the peak hour periods. The analysis involved two major stages: (1) development of simulation and deterministic models used to generate traffic flow parameters, including speed and driving cycles for the study areas; and (2) employment of the traffic flow parameters from stage 1 to quantify the hourly emissions. Three scenarios were analyzed to quantify the air-quality associated with M-Tag deployment. The first scenario involved the pre-M-Tag deployment condition. The second scenario was based on the initial condition following the deployment of M-Tag, and involved market penetration levels ranging from 21 percent to 28 percent at the three toll plazas. The third scenario represented the current condition involving approximately 50 percent M-Tag market penetration level. A comparative analysis of the pre-M-Tag and post-M-Tag deployment scenarios showed 40 to 63 percent reduction of hydrocarbon and carbon monoxide, and approximately 16 percent reduction of nitrogen oxide in the study area. The results were similar for the simulation and deterministic models. It was also observed from the study that the performance of M-Tag system has improved significantly, because motorists are increasingly familiar with the system, resulting in fewer incidents of weaving-related problems at the toll plazas.
