Exploration of Short-Term Vehicle Utilization Choices in Households with Multiple Vehicle Types

Transportation Research Record: Journal of the Transportation Research Board, 2015
With the growing concerns of energy sustainability, greenhouse gas emissions, and climate change, there is an increasing interest in understanding vehicle ownership and utilization decisions better so that effective policies can be implemented to reduce the negative impacts of private automobile usage. Although there is a rich body of literature on the

Multiobjective Approach to Creating Bus Timetables with Multiple Vehicle Types

Transportation Research Record: Journal of the Transportation Research Board, 2012
In times of climate change and scarce resources, it is essential to reduce emissions and to use fuel as economically as possible. The transportation sector alone accounts for 44% of the energy use in New Zealand, with only about one-quarter of that amount being used by the transportation industry for transporting goods.

Study on Optimization of Vehicle Routing Problem with Multiple Vehicle Type and Vehicle Access Restricted Based on Genetic Algorithm

Applied Mechanics and Materials, 2013
In many cities, large trucks cant be used to delivery in the urban district, but in the suburbs all kinds of vehicles can be used. To solve the problem, this paper establishes the optimization model and designs a solving method using a genetic algorithm (GA), taking Zigong tobacco distribution center for example.

Hierarchical hybrid trajectory planning for autonomous vehicle considering multiple road types

Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2022
This paper combines A* algorithm and quintic polynomial to propose a novel hybrid trajectory planning method that can be used on both structured and unstructured roads for autonomous vehicle. The architecture of our approach can be generally divided into two layers.

Human control of multiple unmanned vehicles

Proceedings of the 1st ACM SIGCHI/SIGART conference on Human-robot interaction, 2006
The number and type of unmanned vehicles sought in military operations continues to grow. A critical consideration in designing these systems is identifying interface types or interaction schemes that enhance an operator's ability to supervise multiple unmanned vehicles. Past research has explored how interface types impact overall performance measures

Optimization Allocation of Aerospace Ground Support Vehicles for Multiple Types of Military Aircraft

2017
As an important class of support resources, the allocation of aerospace ground support vehicles (AGSV) has important impact on the sortie generation rate of multiple types of military aircraft (MTMA). In this paper, a general queueing model of AGSV has been built to describe the features of the support process of MTMA using the multi-class closed ...

Lipophilic Polycation Vehicles Display High Plasmid DNA Delivery to Multiple Cell Types

Bioconjugate Chemistry, 2017
A class of cationic poly(alkylamidoamine)s (PAAAs) containing lipophilic methylene linkers were designed and examined as in vitro plasmid DNA (pDNA) delivery agents. The PAAAs were synthesized via step-growth polymerization between a diamine monomer and each of four different diacid chloride monomers with varying methylene linker lengths, including ...
