Sustainability assessment (SA) is a complex appraisal method. It conducted for supporting decision-making and policy in broad environmental, economic social context, transcends purely technical/scientific evaluation. This paper focusses on the systematisation of knowledge sustainability evaluation, by addressing critical elements focussed domain experts. We make distinction between integrated SA. Our systemic approach outlines how to move from The fundamental differences involved concern...
Official laboratory-measured monitoring data indicate a progressive decline in the average fuel consumption and CO2 emissions of European passenger car fleet. There is increasing evidence to suggest that officially reported values do not reflect actual performance vehicles on road. A difference 30–40% between official real-world estimates was found which has been continuously increasing. This paper reviews influence different factors affect road laboratory. Factors such as driving behaviour,...
Rapid technological developments in autonomous unmanned aerial vehicles (UAV or drones) and an evolving legislation may soon open the way for their large-scale implementation last mile delivery of products. The use drones could drastically decrease labour costs has been hyped as a potential disruptor to parcel industry. Online retailers companies such Amazon, are already filing up patents development multi-level fulfilment centres "drone-beehives" that would allow deployment this technology...
Adaptive Cruise Control (ACC) systems are becoming increasingly available as a standard equipment in modern commercial vehicles. Their penetration rate the fleet is constantly increasing, well their use, especially under freeway conditions. At same time, limited information openly on how these actually operate and differences depending vehicle manufacturer or model. This represents an important gap because number of ACC vehicles road increases, traffic dynamics freeways may change...
The European Commission has been actively involved in the development of World-wide harmonized Light duty Test Cycle (WLTC) and corresponding Procedure (WLTP), is currently working to introduce them type approval (TA) procedure. present study analyzes estimates effects introduction WLTP on average CO2 emissions vehicle energy demands (VEDs) from different segments market. Twenty gasoline eleven diesel vehicles were tested current TA procedure NEDC, evolving WLTP. These tests then used as...
The Worldwide Harmonized Light Duty Test Procedure (WLTP), recently issued as GTR15 by UNECE-WP29, is designed to check the pollutant emission compliance of Vehicles (LDVs) around world and establish reference vehicle fuel consumption CO2 performance. In course development WLTP, Joint Research Center (JRC) European Commission has tested gaseous emissions twenty-one Euro 4-6 gasoline diesel vehicles, on both current type approval test procedure (NEDC) progressive versions WLTP. results, which...
After significant efforts from many parties, the World-wide harmonized Light duty Test Procedure (WLTP) has seen its light first as UNECE Global Technical Regulation and then procedure adopted in type-approval of light-duty vehicles Europe. The paper focuses attention on main procedural differences between WLTP New European Driving Cycle (NEDC), which is test-procedure currently used In general terms appears to be a improvement compared NEDC. two test procedures are identified their impact...
Automated calibration of microscopic traffic flow models is all but simple for a number reasons, including the computational complexity black-box optimization and asymmetric importance parameters in influencing model performances. The main objective this paper therefore to provide robust methodology simplify car-following models, that is, reduce (to calibrate) without sensibly affecting capability reproducing reality. To aim, variance-based sensitivity analysis proposed formulated "factor...
Calibration of car-following models against trajectory data has been widely applied as the basis for studies ranging from model investigation and benchmarking to parameter correlation analysis. Other theoretical issues, such inter- intradriver heterogeneity or multianticipative driving behavior, are also addressed in studies. However, very few these attempted analyze quantify uncertainty entailed calibration process its impacts on accuracy reliability results. A thorough understanding whole...
Road vehicles are characterized by increasing levels of automation and it is vital to understand the future impact on transport efficiency. Adaptive Cruise Control (ACC) one first most common automated functionalities available in privately owned vehicles. The effect ACC traffic flow has been widely studied making assumptions its operating strategy some important parameters such as response time desired headway. In literature, these usually set low values, based vehicle controller's...
In 2014 the United Nations Economic Commission for Europe (UNECE) adopted global technical regulation No. 15 concerning Worldwide harmonized Light duty Test Procedure (WLTP). Having significantly contributed to its development, European is now aiming at introducing new test procedure in type-approval legislation light vehicles order replace New Driving Cycle (NEDC) as certification test. The current paper aims assess effect of WLTP introduction on reported CO2 emissions from passenger cars...
Adaptive cruise control (ACC) systems are standard equipment in many commercially available vehicles. They considered the first step of automation, and their market penetration rate is expected to rise, along with interest researchers worldwide assess impact relation traffic flow stability. These properties currently discussed mainly through microsimulation studies empirical observations, being most common. Experimental observations can draw safer conclusions about behavior such systems, but...
Connected and automated vehicles (CAVs) promise to significantly improve road traffic. To a certain extent, this situation is similar the expectations at end of last century about positive effects that introduction Adaptive Cruise Control (ACC) systems would have had on motorway The parallelism interesting because ACC equipped represent first level vehicle automation are now widely available market. In light, studying impacts can help anticipate potential problems related its widespread...
Abstract Background Road transport is an important contributor to the European Union’s total greenhouse gas emissions. This study aims at summarizing methane (CH 4 ) and nitrous oxide (N 2 O) exhaust emissions from L-category, light-duty heavy-duty vehicles in Union.

The expectations for post-COVID recovery of transport activity point towards a gradual return to normality, once the pandemic is under control and mobility restrictions end. shock society economy has, however, caused number behavioural changes that can influence evolution sector. We analyse main factors future supply demand explore how they may affect trip generation, distribution modal split in passenger transport. combine several conventional innovative data sources with detailed strategic...
Abstract “Car dependence” emerges as an academic concept supported by decades of multidisciplinary research, which aims to understand the factors that drive car-based choices. The variety approaches and indicators used interpret this phenomenon underscores its multidimensionality highlights necessity for a comprehensive framework define operationalise it. This paper contributes goal conducting systematic literature review examines indicators, associations, meanings research in defining...
Researchers and practitioners commonly use car-following models for road traffic studies. Although dozens of have been presented so far, the one proposed by Peter G. Gipps in 1981 is still most extensively used. However, many features model are not well known or neglected common applications. In this context, current study summarizes analyzes main findings available scientific literature Gipps’ introduces some its novel that may improve capability to reproduce real trajectory data....
Common approaches to assess the evolution of CO2 emissions from road vehicles are usually based on (a) estimates future fleet composition, where most consider at a rather aggregated level, and (b) emission factors, which either certification data or statistically-provided functional relationships obtained real world test data, combination two. This approach has certain limitations in capturing effect new technologies related policy initiatives. The present study proposes method for detailed...
