|Standard number:||21/30410831 DC|
|Status:||Draft for Comment|
This standard 21/30410831 DC BS ISO 23795-1. Intelligent transport systems. Extracting trip data via nomadic device for estimating CO2 emissions is classified in these ICS categories:
- 13.020.40 Pollution, pollution control and conservation
- 13.040.50 Transport exhaust emissions
- 35.240.60 IT applications in transport and trade
- 43.040.15 Car informatics. On board computer systems
The scope of the standard is to specify a method for the determination of fuel and CO2 consumption to enable fleet managers to reduce fuel costs and Greeen House Gas (GHG) emissions in a sustainable manner. The fuel consumption determination is achieved by extracting trip data and speed profiles from the GNSS receiver of a nomadic device, by sending it via mobile communication to a data base server and by calculating the deviation of the mechanical energy contributions ofAerodynamic,
Acceleration / Braking,
relative to a given Reference Driving Cycle in [%]. As the mechanical energy consumption of the Reference Cycle is known by measurement with a set of static vehicle configuration parameters, the methodology enables drivers, fleet managers or logistics service providers to calculate and analyse fuel consumption and CO2 emissions per trip by simply collecting trip data with a satellite equipped nomadic device inside a moving vehicle. Besides of an on-trip and post-trip monitoring of energy consumption (fuel, CO2), the solution also provides information about eco-friendly driving behaviour and road conditions for better ex ante and ex post trip planning. Therefore, the solution also allows Floating Cars to evaluate the impact of specific traffic management actions taken by public authorities with the objective of achieving GHG reductions within a given road network.
The nomadic device is not aware of the characteristics of the vehicle. The connection between dynamic data collected by the nomadic device and the static vehicle configuration parameters is out of scope of the present document. This connection is implementation dependent for a software or application using the described methodology which includes static vehicle parameters and dynamic speed profiles per second from the nomadic device.
Considerations of privacy and data protection of the data collected by a nomadic device are not in scope of the present document which only describes the methodology based on such data. However, software and application developers using the methodology need to carefully consider those issues. Nowadays, most countries and companies have to be compliant with strict and transparent GDPR regulations and have the corresponding approval boards and certification regulations in force before bringing new products to the market.
