16. Abstract This report summarizes the findings of an independent evaluation of the FHWA Cross-town Improvement Project (C-TIP), which was deployed in Kansas City and Chicago in various periods from October 2010 through September 2011. The Dynamic Route Guidance (DRG) and Real-Time Traffic Monitoring (RTTM) components of C-TIP achieved measurable dray truck travel time savings and emissions reductions in operational tests. Separate deployments of in-cab smart phones running the C-TIP Open Source Architecture Package with drayage companies in Kansas City and Chicago achieved measurable reductions in bobtails even as revenue loads grew or remained stable. Simulations of the Intermodal Move Exchange (IMEX) component of C-TIP revealed the potential to reduce bobtails through better information sharing between cross-town railroads and drayage firms. There were some operational constraints to full utilization of C-TIP in Kansas City. Changing railroad business practices, along with a generally low level of economic activity during the test, contributed to a lack of railroad participation in the program. More broadly, the test experience suggests that the intermodal industry probably lacks the collaborative mentality to make a cooperative dispatch platform work. Nonetheless, this initial deployment of C-TIP technologies did prove the concept that such applications can provide public and private sector benefits including congestion mitigation, emissions reductions, and truck travel time savings. The results suggest that future research may be best targeted towards freight information exchange, improving the truck dispatch operation, and in providing real-time information and tools to support truck routing decisions. |
