Today, there are two major paradigms for vision-based autonomous driving systems: mediated perception approaches that parse an entire scene to make a driving decision, and behavior reflex approaches that directly map an input image to a driving action ...

The safety of vulnerable road users (VRU) (e.g., pedestrians, bicyclists) can be improved by sharing their position and context information with vehicles over a wireless communication channel. However, challenges exist in managing transmission in ...

Connected and automated vehicle (CAV) technologies are believed to offer tremendous benefits to the urban transportation system. Intersection control will also experience a transition process from the state-of-the-practice paradigm to a fully CAV ...

As vehicle communication standards mature, protecting vulnerable road users (VRUs) using vehicle communication technology is looming as a promising and useful application. The current vehicle-to-pedestrian (V2P) communication as stipulated by the ...

Traditionally, the vehicle has been the extension of the manual ambulatory system, docile to the drivers' commands. Recent advances in communications, controls and embedded systems have changed this model, paving the way to the Intelligent Vehicle Grid. ...

With Wireless Access in Vehicular Environment (WAVE) finalized for legal enforcement from 2020 after the recent move by the U.S. Government, data plausibility is still an unresolved security issue. In particular, an attacker may forge false position ...

Automakers have already started rolling out cars with communication capabilities. They become more than simple means of transportation - their mobility combined with networking lets them interconnect people and machines. Looking at the network part, the ...

People's driving behavior is influenced by different human and environmental factors, and several attempts to characterize it have been proposed. Nowadays, the standardization of the CAN bus and the increase of the electronic components units in modern ...

Due to the growth of intelligent and self-driving vehicles, there are a multitude of data-driven applications such as user monitoring or traffic modeling and control. Each application often uses its own data-collection platform, leading to a scattered ...

Control of conventional transportation networks aims at bringing the state of the network to the system optimal (SO) state. This optimum is characterized by the minimality of the social cost function, i.e., the total cost of travel of all drivers. On ...

Vehicular networks are envisioned to cover various use cases from safety related applications to infotainment. While there exist standardized solutions for exchanging single messages in a geographical area, coping with longer lasting flows of messages ...

We consider the problem of managing Firmware Over-The-Air (FOTA) updates for cars at a massive scale over a cellular network. This problem is constrained by factors like large number of cars, a need to perform updates quickly and securely, ability to do ...

Vehicular network architectures are being reviewed and re-designed to meet requirements for increasing data rates and flexibility driven in part by the adoption of Connected and Automated Vehicles (CAV) strategies. A progressive move from traditional ...

Broadcasting/multicasting offers a potential benefit for delay-sensitive applications in vehicular networks, since information could be delivered to multiple receivers simultaneously by a single transmission. However, conventional broadcasting schemes ...

Doppler effects on vehicular communication have been theoretically modeled by many researchers. However, very limited experimental studies have been conducted to investigate the impact of Doppler shift on the vehicle-to-vehicle (V2V) communication range ...

Pedestrians are particularly vulnerable traffic participants and, therefore, accurate localization and reliable communication between them and vehicles are of utmost importance to ensure their safety. A common method to determine distances between ...

RadioRateTransformer is a broadband wireless routing system that can implement ~10Mbps high-speed ad-hoc networks for mobile vehicles at 10km/20km/30km long distance per link. It legally leverages VHF/UHF radio's large transmission power allowed by FCC ...

This paper presents the development of a novel decentralized freeway merge assistance system using the Dedicated Short Range Communication (DSRC) technology. The system provides visual advisories on a Google map through a smart phone application. To the ...
