Direct video measurements of surface street truck traffic at eleven intersections and line segments in communities adjacent to southern California ports document that volumes of portrelated trucks often reach 400-600 per hour for several hours, immediately upwind of ‘sensitive’ land uses such as schools, open-field parks and residences. The diurnal fluctuation of trucks on surface streets varie...

Container movement by trucks with time constraints at origins and destinations is modeled as an asymmetric “multi-Traveling Salesmen Problem with Time Windows” (mTSPTW) with social constraints. A two-phase exact algorithm based on dynamic programming (DP) is proposed that finds the best routes for a fleet of trucks. Since the m-TSPTW problem is NP-hard, the computational time for optimally solv...

The application of multi-agent platform for real-time adaptive scheduling of trucks is considered. In case of unpredictable events the system works adaptively and doesn’t stop to restart the plan from the beginning. Different models of cargo transportation for truck companies having own fleet are analysed. The results show that using adaptive scheduling in real time it is possible to create sig...

T amount of pollution that a vehicle emits and the rate at which it consumes fuel are dependent on many factors. The U.S. Environmental Protection Agency (EPA) has developed a series of computer models that estimate the average emissions for different types of highway vehicles. This fact sheet is one of a series on highway vehicle emission factors. It presents average annual emissions and fuel ...

A particular routing problem is considered: a customer asks to load a quantity at one place and to transport it to another one. The aim is to determine the daily routes of a fleet of trucks satisfying the requests of a set of customers. Several constraints must be considered: maximal duration of the daily routes; time-windows at the loading points; request of a particular type of trucks. Severa...

This paper analyzes an integrated inventory control and transportation problem with environmental considerations. Particularly, explicit transportation modeling is included with inventory control decisions to capture per truck costs and per truck capacities. Furthermore, a carbon cap constraint on the total emissions is formulated by considering emission characteristics of various trucks that c...

The objective of this study was to assess the effects of projected truck traffic on the highway system of Texas in consideration of the social and economic vitality of the State. The study included the evaluation of the costs and benefits for a twenty-year planning horizon. Alternative scenarios of future truck traffic were assessed. The study did not consider the effects of changes in the size...
