In this paper, energy dissipation (ED) rate and particulate matter emission (PME) rate were investigated by local measurements between the warning sign and the traffic bottleneck based on a two-lane NaSch cellular automaton model. The aim of this study was to present the variation trend profiles of ED and PME caused by traffic bottleneck with traffic flow states and associate it with particular factors. Factors including the exchange success rate of vehicles on the reduced lane, length of the lane reduction, setting distance of warning sign before the traffic bottleneck, speed limit, and safety distance were discussed in the periodic boundary condition by making comparison with a simulated benchmark case, respectively. Impacts from the injection rates and extinction rate of the lane were also been investigated in the open boundary condition. Results showed that proper location of the warning sign, reasonable speed limit, and keeping downstream uncongested have significant effect on reducing ED and PME.
