In brief Calculating carbon emissions for less than truckload (LTL) is more challenging than for other modes of transportation. Each LTL truck combines a wide mix of freight from many shippers, with varying origin-destination pairs. Without visibility to the details about individual shipments on that truck, accurate carbon emission estimates at the shipment level can be difficult to obtain. Gra...

We deployed a recently proposed single loop detector based, real-time freeway truck traffic volume estimation algorithm to a County-level traffic database. The scale-up of the algorithm is achieved by adding an extra layer, consisting of a spatial filtering component for removing noise and an aggregation component for efficient analysis. All calculations could be done in real-time to produce a ...

The Ports of Long Beach and Los Angeles are the largest container port complex in North America and fifth largest in the world. Growth in U.S. Pacific Rim trade has put pressure on the landside transportation systems serving these two ports. In order to address this growth and mitigate environmental impacts, the ports are implementing new operational strategies and infrastructure improvements. ...

16 Freight movement complexity and a lack of truck trip data limits freight modelling’s practicality 17 and application. Most publicly available truck movement data is reported at higher geographical levels 18 than detailed analysis and modelling require. The current Freight Analysis Framework (FAF) provides 19 freight data based on the Commodity Flow Survey (CFS) conducted every five years wit...

VMT and vehicle classification are vital inputs in the design and operation of an efficient transportation infrastructure system. In particular, heavytruck VMT is important as the number of heavy vehicles on a road affects traffic operations, safety, and pavement performance. Research has revealed that current methods used in the estimation of heavy-truck VMT are often less accurate than those ...

For articulated vehicles met in robotics and transportation fields, even for an experienced operator, backing-up leads usually to jack-knifing. This paper presents a fuzzy logic controller for back-driving a truck-trailer vehicle into a predefined parking task. The truck-trailer link system is equipped with a kingpin sliding mechanism acting as an anti-jackknife excitation input. By applying fu...

Agricultural transportation is often characBACKGROUND terized by seasonal and cyclical traffic flows that unfavorably affect the logistical efficiency of the marketing system. Congestion problems are an important link in the arise in the truck-to-ship intermodal grain export grain marketing system. Currently, 66 transfer system at the Port of Houston. Seaport elevators operate in the U.S. and t...

This paper focuses on the procurement of full truck-load transportation service with the view to ensuring sustainability in transport logistics. The carrier assignment problem (CAP) involved in truck load contract auction is studied using a complete enumeration method and heuristic approach. Performance of both methods is compared in terms of solution quality and computational time based on the...

At cross docking terminals incoming deliveries of inbound trucks are unloaded, sorted, moved across the dock and nally loaded onto outbound trucks, which immediately leave the terminal towards their next destination in the distribution chain. Accordingly, a cross dock is a consolidation point in a distribution network, where multiple smaller shipments can be merged to full truck loads in order ...
