Abstract. Particulate matter (PM) and nitrogen oxides NOx (NOx = NO2 + NO) are key species for urban air quality in Europe and are emitted by mobile sources. According to European recommendations, a significant fraction of road freight should be shifted to waterborne transport in the future. In order to better consider this changed emission pattern in future emission inventories, in the present study, inland water transport emissions of NOx, CO2 and PM were investigated under real world conditions at the river Rhine, Germany in 2013. An average NO2/NOx emission ratio of 0.08 ± 0.02 was obtained, which is indicative of ship diesel engines without after-treatment systems. For all measured motor ship types and operation conditions overall weighted average emission indices of EINOx = 54 &amp;pm; 4 g/kg and a lower limit EIPM1 = ≥ 2.0 &amp;pm; 0.3 g/kg were obtained. EIs for NOx and PM1 were found to be in the range of 20–161 g kg−1 and ≥ 0.2–8.1 g kg−1, respectively. A comparison with threshold values of national German guidelines shows that the NOx emissions of all investigated motor ship types are above the threshold values, while the obtained lower limit PM1 emissions just within. To reduce NOx emissions to acceptable values, implementation of after-treatment systems is recommended.

Performance Measurement Systems

The inland waterway freight transportation system plays a vital role in the trade and commerce of the U.S.A. To ensure that the system performs at an acceptable level, routine monitoring and performance evaluation of the system is critical. Individual states are responsible for developing and implementing suitable performance measurement systems for their respective inland waterways. This paper focuses on surveying, reviewing, and synthesizing current performance measurement practices adopted by different states in the U.S.A. It finds that, among the 38 states with inland navigability, only 12 states have established performance measures to monitor the performance of their inland water transportation systems. To aid the states in developing and enhancing inland waterway performance measurement programs, the paper further outlines the current state of research on inland waterways, recommendations from various federal and maritime organizations, and also current practice outside of the U.S.A. Based on a scan of the publicly available data sources, the paper proposes a two-dimensional performance measurement practice from the perspectives of performance areas and infrastructure types. Such an approach will help state Departments of Transportation to identify system needs and deficiencies while offering a comprehensive picture of performance of an inland water freight transportation system.
