Collaborative Road User Safety Service

Term Definitions Collaborative Safety Device (CSD) A device that allows road users to record and share the safety-related behaviors of other road users. Collaborative Road User Safety Service (CRSS) A system that collects, analyzes, and distributes road user safety information. Annotated Event When an initiating member submits a report about a safety-related behavior of a target road user's vehicle. Annotation Request A report submitted by an initiating member that contains identification information and safety data of the target vehicle. Safety data Information describing the safety-related behavior of the target road user's vehicle, e.g., reckless driving, speeding, etc. Vehicle identification data Information used to identify the target vehicle, e.g., license plate number, vehicle description, etc. Initiating Member A CRSS member that initiates an Annotated Event. Target Member A CRSS member whose vehicle is the target of an Annotated Event. Confirming Member A CRSS member that is requested to confirm the Annotated Event information. Confirming Device A CSD device used by a Confirming Member. Confirmation Request A request sent by the CRSS to a Confirming Device to confirm the Annotated Event information. Confirmation Response A reply from a Confirming Device to an Confirmation Request, containing Confirmation Data. Confirmation Data Information provided by a Confirming Device to support or refute the Annotated Event information. Annotated event weight score is a score that indicates the credibility and severity of an annotation event. Composite safety rating is a rating calculated based on the annotated event history associated with a specific vehicle or member. Crypto tokens are digital assets used to incentivize CRSS members to participate and provide high-quality data. Incentive transactions are transfers of crypto tokens that occur when CRSS members participate in specific events. Authorized data subscribers are specific entities that can access road user data collected by CRSS. Self-correcting incentives are incentive mechanisms that automatically adjust when specific conditions are met. Distributed application network is a decentralized network used to store CRSS data. Distributed ledger is an immutable record of data stored in a distributed application network. Smart contract is a self-executing contract deployed on a distributed application network.

Short answer question

What is the main goal of the Collaborative Road User Safety Service (CRSS)?

Answer: The main goal of CRSS is to improve road safety by leveraging the power of the road user network. It allows users to report unsafe driving behaviors and provide early warnings to other users based on the data collected.

What key information is included in the annotation request?

A: A callout request contains identification information of the target vehicle, such as a license plate number or vehicle description, and safety data, such as a description of the unsafe driving behavior observed. It also includes GPS data from the initiating device.

How does CRSS utilize GPS data?

A: GPS data is used to determine the location of the initiating device, estimate the location of the target vehicle, and identify confirming devices that may be in the area. It can also be used to analyze road and traffic conditions.

What is the purpose of a confirming request?

A: The purpose of a confirming request is to verify the validity of a callout request submitted by an initiating member from multiple sources. Confirming members may be asked to confirm the presence of the target vehicle or provide additional information.

How does CRSS use sensor components and telemetry data?

A: Sensor components, such as cameras or accelerometers, and telemetry data, such as speed or braking data, can be provided by confirming devices to support or refute information about a callout event and provide a more objective record of driving behavior.

What is the significance of the callout event weight score?

A: The callout event weight score represents the confidence and severity of the callout event. It is calculated based on factors such as confirmation data, operating conditions, and historical data.

How does the composite safety rating affect incentives in CRSS?

A: The composite safety rating reflects the overall safety record of a particular vehicle or member. A higher rating can lead to greater rewards or fewer penalties, while a lower rating can lead to stricter penalties or fewer rewards.

How can authorized data subscribers use CRSS data?

A: Authorized data subscribers, such as law enforcement agencies, insurance companies, or research institutions, can use CRSS data to identify dangerous driving trends, investigate accidents, or develop strategies aimed at improving road safety.

What is the role of self-correcting incentives in CRSS?

A: Self-correcting incentives provide a dynamic incentive mechanism for improvements in driving behavior. For example, if a driver maintains a good driving record for a specific period of time, the penalty initially imposed for a violation may be reduced or eliminated.

How does distributed ledger technology enhance the functionality of CRSS?

A: Distributed ledger technology, such as blockchain, enhances CRSS by creating a secure, transparent, and tamper-proof record of transactions. This helps ensure the integrity of the data and the overall reliability of the CRSS.
