We study a problem appearing at the end of a logistic stream in a warehouse and which concerns the timetabling of sorting slots necessary to accomodate the prepared orders before being dispatched. We consider a set of orders to be prepared on some preparation shops over a given time horizon. Each order is associated with the truck handling its transportation to its customer. A sorting slot is a...

In recent years, governments applied intelligent transportation system (ITS) technique to 8 provide several convenience services (e.g., garbage truck app) for residents. This study proposes a 9 garbage truck fleet management system (GTFMS) and data feature selection and data clustering 10 methods for travel time prediction. A GTFMS includes mobile devices (MD), on-board units, fleet 11 manageme...

BACKGROUND Associations between traffic pollution on the street of residence and a range of respiratory and allergic outcomes in children have been reported in developed countries, but little is known about such associations in developing countries. METHODS The third phase of the International Study of Asthma and Allergies in Childhood (ISAAC) was carried out in 13- to 14-year-old and 6- to 7...

The effect of trucks on the level of service is determined by considering passenger car equivalents (PCE) of trucks. The current version of Highway Capacity Manual (HCM) uses a single PCE value for all tucks combined. However, the composition of truck traffic varies from location to location; therefore, a single PCE value for all trucks may not correctly represent the impact of truck traffic at...

Using two years of crash and average annual daily traffic data we examine the locations and conditions linked to truck-involved crashes (accidents). A binomial logit model is used to describe how the probability that a crash involves a truck is a function of the percentage of annual average daily traffic that is accounted for by trucks, time of day, day of the week, weather conditions, mix of t...

The issue of truck accidents on urban freeways is a vital concern for both traffic managers and the general public. The passage of the Surface Transportation Assistance Act of 1982 and recently the North American Free Trade Agreement has increased the numbers of large combination vehicles on the highway system. The rise in truck volume (defined as vehicles exceeding 4.5 Mg (10,000 lbs), the int...

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...

This short article presents control designs of truck braking system. It describes design comparisons among the simple internal model control (SIMC), Ziegler-Nichol (ZN), Cohen-Coon (CC) methods, and the proposed bacterial-foraging-tabu-search (BFTS) metaheuristics. The proposed BF-TF algorithms are explained. The article also presents simulation results and discussions. Keywords—truck braking c...

Weigh-in-Motion (WIM) systems are used, among other applications, in pavement and bridge reliability. The system measures quantities such as individual axle load, vehicular loads, vehicle speed, vehicle length and number of axles. Because of the nature of traffic configuration, the quantities measured are evidently regarded as random variables. The dependence structure of the data of such compl...
