Autonomous driving vehicles are becoming popular as a solution to reach safe, efficient and comfortable mobility. However, at early market penetration, autonomous vehicles based on Cooperative ACC (C-ACC) policies will have to co-exist in mixed traffic conditions with less autonomous vehicles, such as Adaptive Cruise Control (ACC) or conventional vehicles. In this paper, we introduce a simple c...

In this paper an uncapacitated multiple allocation p-hub median problem is discussed. The model minimizes the transportation cost based on inventory service level at hubs through double paths between hubs. Inventory service level is defined as the percent of inventory shortage of vehicles at hubs according to passengers demand and replenishment time of vehicles. A real data from 25 nodes of mun...

The objective of this project is to detect and track vehicles in a video and to classify if these vehicles are long vehicles or regular vehicles. The video will be recorded from a surveillance camera at a fixed perspective. And the camera is aimed at the central part of the intersection. Then the vehicles passing through the intersection will be recorded. MATLAB will be used as the main softwar...

The percentage of illegal parking in spaces reserved for the physically disabled was monitored under three sign conditions: ground markings, ground markings plus vertical signs, and vertical signs containing a message that concerned citizens were watching the spaces. Illegal parking dropped from 69.3% of 102 vehicles during the initial ground-sign condition to 57.3% of 36 vehicles in the first ...

Purpose: discuss actual application value of the diffusion theory in massive electric vehicle charging load. Method: introduce single vehicle charging process, extend it to charging process of two and multiple electric vehicles, abstract physical process of parallel charging of electric vehicles, introduce energy block concept and diffusion theory, and establish diffusion charging model of elec...

One of the big concerns of big cities is facing with the increase of fossil fuel vehicles in the roads. The cars intensify greenhouse gas emission in civic centers. One approach to reduce the emission is replacing the cars by Plug-In Electric Vehicles (PEVs). In spite of reducing the emission, PEVs have some adverse effect on electric distribution networks. Technical challenges such as load and...

The power required by flapping and fixed wing vehicles in level flight is determined and compared. Based on a new modelling approach, the effects of flapping on the induced drag in flapping wing vehicles are mathematically described. It is shown that flapping causes a significant increase in the induced drag when compared with a non-flapping, fixed wing vehicle. There are two effects for that i...

The introduction of semiautomated vehicles designed to operate with manually driven vehicles is a realistic near-term objective. The purpose of this paper is to analyze the effects on traffic-flow characteristics and environment when semiautomated vehicles with automatic vehicle following capability (in the same lane) operate together with manually driven vehicles. We have shown that semiautoma...
