Compressed Natural Gas (CNG) Sweeper Operation Evaluation Several counties across California have begun to switch from diesel-powered street sweepers to CNG (Compressed Natural Gas) street sweepers, in order to comply with Federal and State air quality regulations. In this talk, we study the productivity and cost impact of using CNG sweepers as opposed to the diesel sweepers in Caltrans District 7. Our productivity comparison was based on lane miles (LAMI) data provided from IMMS. We analyzed resource usage data based on LAMI from 2002-2008 as recorded in IMMS. Maged M. Dessouky, Ph.D., is a Professor of Industrial and Systems Engineering, University of Southern California. Dr. Dessouky has an in-depth theoretical and practical understanding of models and heuristic methods for transportation system optimization. He received his Ph.D. in Industrial Engineering from University of California, Berkeley, and M.S. and B.S. degrees from Purdue University. He is the Area Editor of Planning and Scheduling for the International Journal of Computers & Industrial Engineering and of Transportation for the ACM Transactions of Modeling and Simulation. He was recipient of the 2007 Transportation Science & Logistics Best Paper Prize ("Optimal Slack Time for Schedule-Based Transit Operations") and is a Fellow of the Institute of Industrial Engineers. |

Revisiting the Estimation of Highway Maintenance Marginal Costs This research focuses on the estimation of highway maintenance marginal costs. Highway maintenance marginal cost has been estimated in the literature using the perpetual overlay indirect approach. This approach assumes that pavement overlay costs dominate maintenance costs and ignores other maintenance activities. This paper focuses on two questions. First, is it acceptable to ignore the less costly activities? Second, if multiple maintenance activities are to be considered, is it acceptable to ignore their interdependence? The results show that less costly maintenance activities cannot be ignored. Furthermore, if multiple activities are to be considered, their interdependence should be taken into account. Samer Madanat is the Xenel Distinguished Professor in the Department of Civil & Environmental Engineering, and the Director of the Institute of Transportation Studies at the University of California at Berkeley. His research and teaching interests are in the area of Transportation Infrastructure Management, with an emphasis on modeling facility performance, development of optimal management policies under uncertainty, and improving the sustainability of transportation infrastructure maintenance policies. |

THIRD SPEAKER HAS CANCELED. APOLOGIES FOR THE DISAPPOINTMENT. PLEASE LOOK FOR HIS PRESENTATION IN FUTURE SEASONS OF THE NEW RESEARCH WEBINAR SERIES.System-wide Ramp Metering as a Policy Tool to Induce Efficient Travel in a Freeway Corridor In this talk, we present results from a recent study of the potential for ramp metering to redistribute the costs of congestion and induce an efficient travel demand pattern. That is, to use access control to eliminate congestion inside the network. Modeling a freeway corridor during morning commute, we studied access control strategies under different corridor network configurations, considering a wide variety of bottleneck locations, commuters' distributions among origins, schedule delay functions, values of time on different facilities, the presence of HOV/HOT lanes, and so forth. Michael Zhang is a Professor of Civil and Environmental Engineering at the University of California, Davis. His research intersets include transportation systems operations, traffic flow theory, traffic control, dynamic traffic assignment, and intelligent transportation systems. |
