Abstract

Measurements from a Houston tunnel were used to develop fuel consumption-based emission factors for CO, NOx, and non-methane organic compound (NMOC) for on-road gasoline vehicles. The Houston NO x emission factor was at the low range of emission factors reported in previous (primarily pre-1996) tunnel studies while the NMOC emission factor was slightly higher than that reported in the previous tunnel studies.
