Necessity of Connected Vehicles
Necessity of Connected Vehicles
Vehicle wireless communication can provide a lot of new applications, the most delicate of which are class of security applications that can minimize accidents and save thousands of lives. The automotive industry is continuously working to build a dedicated short-range communication technologies (DSRC) for use in automotive and automotive communications. The effectiveness of this technology largely depends on the rules of joint interaction. This article will allow the reader a good understanding of the DSRC technology for automotive communications, including the DRSC value, the experts who can develop it, use it and, most importantly, its benefits.
WHAT IS DSRC?
DSRC (Dedicated Short Communication) – a two-way wireless communication with short and medium range, providing very high data transfer is critical for active security applications based on communication. The FCC-03-324 (FCC) Federal Communications Commission has allocated 75 MHz of spectrum in the 5.9 GHz frequency band for use in security and mobility application systems Intelligent Transport Systems (ITS). Communication based on DSRC is one of the top priorities of the Research Office of the Joint STI Program (JPO) in the Office of Research and Innovation Technologies US Department of Transportation (ROTA). Cross-modal program conducts research using DSRC and other wireless technologies to provide secure and interoperable communications, which helps prevent traffic accidents of all kinds and to increase mobility and environmental benefits in all modes of system transport.
Commitment to DSRC US DOT communications for active safety contributes to safer driving. Applications to ensure the safety of vehicles using the connection between vehicle (V2V) and vehicle (V2I), need reliable and reliable wireless communication in extreme weather conditions and short-term delays; All of which are facilitated by DSRC.
WHO ARE THE EXPERTS THAT CAN DEVELOP THE DSCR TECHNOLOGIES?
Device manufacturers, application developers, representatives of the automotive industry, telecommunications, consumer electronics and other industries whose products pass alerts on vehicles, infrastructure or personal communication devices that travel.
HOW DOES IT WORK?
V2V and V2I applications, using the DSRC, may have the potential to significantly reduce many of the most deadly types of real-time message failures, warns the driver of imminent danger, such as a deviation from the roadside; Nave stopped suddenly; Of the collision in the union; The availability of neighboring communication devices and vehicles; Curves closed or slippery road ahead spots. V2I convenient services such as electronic parking payment and payment services can also be communicated through DSRC. Anonymous information from electronic sensors of vehicles and devices can also be transmitted through DSRC to provide better information on traffic and driving conditions for travelers and transport managers.
Connected Vehicle ITS applications provide connectivity
• Among cars that can prevent accidents
• Between vehicles and infrastructure to ensure safety, mobility and environmental sustainability
• Between vehicle wireless devices, infrastructure and passengers to ensure continuous real-time communication to all users of the system
DSRC support technology to prevent failures and mobility
• Active security requests
• Secure, reliable communications
• Low latency data transfer rate
• Immune to extreme weather conditions
• The tolerance of multipath transmission
• The technology is based on interoperability standards
Why was DSRC developed and to what benefit?
DSRC has been designed with the primary goal – to provide technologies that support application security and communication between vehicle-based devices and infrastructure to reduce collisions. Today DSRC is the only alternative to a wireless network, which provides:
• Licensed bandwidth Assigned: for secure and reliable communications. It is intended primarily for application security vehicles in the FCC Report and Order FCC 03-324.
• Quick assembly to the network. Active security applications require immediate communication and frequent updates.
• Low latency: Active security applications have to recognize each other and to send messages to each other in milliseconds without delay.
• High reliability, if required: a high level of reliability of the connections required for active safety applications. DSRC is under high mobility vehicles and provides resistance to extreme weather conditions e.g. rain, fog, snow, and so on.
• Priority security applications: Security applications in DSRC given priority compared to unsafe applications.
• Interaction: DSRC provides interoperability, which is the key to the success of deploying active security applications using a common standard. It supports both V2V, V2I and-bond.
• Security and privacy: DSRC provides authentication and privacy security posts.
DSRC allows the use of the most reliable, high-speed vehicles for shock safety
DSRC offers a broad cross-section of connectivity dedicated to ensuring the safety of ground transportation
DSRC-based communication is the foundation for the integration of security applications, and mobile applications
Potential DSRC transport services for public safety and traffic management
• Warnings about blind spots
• Forward collision warning
• Warning in front of sudden braking
• Do not miss the warning
• Avoid collisions and help with movement
• When approaching the emergency alert on the vehicle
• Checking vehicle safety
• Signal priority of the vehicle or emergency vehicle
• Electronic parking and toll fees
• Commercial vehicle inspections and security controls
• Signature by car
• Warning of a rollover
• Data on the state of transport and travel, and to improve passenger service
Finally, following the deployment of DSRC by its service can potentially provide important road safety, traffic management and environmental benefits. These services can support a safer, faster and more environmentally friendly journey on the roads of our country. However, these benefits could be seriously undermined – and possibly extinguished – harmful interference from new untested DSRC devices.
