Effects of using Synthesized Driving Cycles on Vehicle Fuel Consumption

Creating a driving cycle (DC) for the design and validation of new vehicles is an important step that will influence the efficiency, functionality and performance of the final systems. In this work, a DC synthesis method is introduced, based on multi-dimensional Markov Chain, where both the velocity and road slope are investigated. Particularly,...

Update analysis of real-world fuel consumption of business passenger cars based on Travelcard Nederland fuelpass data

Het verschil tussen normverbruik en praktijkverbruik van voertuigmodellen uit 2013 is opnieuw toegenomen. Het verschil tussen het normverbruik en het praktijkverbruik is, echter, minder groot dan eerder werd gedacht.

Uncertainties in emissions of road traffic: Euro-4 diesel NOx emissions as case study

Potential benefits of Triple-A tyres in the Netherlands

Methodology and framework architecture for the evaluation of effects of ICT measures on CO2 emissions

Applications of Information and Communication Technologies (ICT) have been identified to have a significant contribution to reduce energy consumption and CO2 emissions in the field of transport. The mechanisms by which ICT have an impact on CO2 emissions can be very complex, and calculating this impact requires various models (e.g. traffic and...

Calibration of a microscopic simulation model for emission calculation

Emissions by road traffic can be reduced by optimising traffic control. The impact of this optimisation on emission can be analysed ex ante by simulation. The simulation programs used for this analysis should be valid with respect to the traffic characteristics that determine the emissions. Thus calibration of the parameters is a prerequisite....

De truck van de toekomst. Brandstof- en CO2-besparing anno 2013

In het demonstratieprogeamma 'Truck van de Toekomst' zijn diverse marktrijpe maatregelen onderzocht waarmee ondernemers binnen de transportsector brandstof kunnen besparen. Deze TNO rapportage kwantificeert de resultaten, zich richtend op brandstofbesparing, terugverdientijd en ervaringen van gebruikers in de praktijk

A velocity and payload dependent emission model for heavy-duty road freight transportation

The paper develops a forecasting model of emissions from traffic flows embracing the dynamics of driving behavior due to variations in payload. To measure of emissions at the level of individual vehicles under varying payloads a portable emission measurement system is used. This paper reports on a model based on data at the level of individual...

Real-time vehicle emission monitoring along roadsides

In the worldwide efforts to reduce the emissions of greenhouse gasses in general and those emitted by vehicles in particular, vehicle emission monitoring is important. It provides accurate knowledge of real-world emissions of vehicles as input for vehicle emission models. Real-time emission monitoring along roadsides can be used in dedicated...

Real-time monitoring of emissions with traffic data, simulation and air quality measurements

This paper investigates the possibility to decide when to apply a (dynamic) traffic management measure to improve the air quality or reduce CO2 emissions, based on a limited set of (measured) data. It is expected that a combination of monitoring and modeling is needed for reliable air quality estimations. Improvements in traffic and emission...

Impact of information and communication technologies on energy efficiency in road transport - Final Report

The application of ITS is seen as very promising to address the negative consequences of road transport. However, the mechanisms which have an impact on the CO2 emissions are very complex, while not much about this is known from existing studies. Therefore, the EC commissioned this study, ‘Impact of Information and Communication Technologies on...
