“…Using drive cycles in chassis dynamometer testing is not always representative of realworld driving cycles [13][14][15], they only cover a limited number of driving modes [16], and it can be seen as a weak point of emission estimation, as vehicles could conceivably be tested differently depending on their performance levels and usage characteristics [17].…”

Air pollution is becoming a very important issue for the transportation sector, particularly car emissions in urban areas, and there is much interest in evaluating the actual level of emissions. In this paper, a case study of a standard driving cycle in the urban area of Dublin city is presented. On-road, speed-time data was extracted by an on-board diagnostic tool, and saved into a data acquisition package. Firstly, the driving cycle was established for the urban area of the city; one car travelling different routes has been employed to implement this research and some representative results have been achieved. The second part of the project was to estimate the emissions from the same car using the driving cycle obtained and compare the results with those obtained by a gas analyzer attached to the car simultaneously in order to validate the methodology used in this paper.A representative driving cycle reflecting the real-world driving conditions is proposed and estimated vehicle emissions were compared with measured results. The method is easy to follow and the results are in a good fit to the estimated values.

“…The most popular macroscopic level emission models include MOBILE, EMFAC [21], COPERT [22] and IVE [23], which are widely used to assess numerous air quality planning functions but request only average speed as the indication of traffic conditions. This input requirement of average speed corresponds to a specific series of pre-defined driving cycles used in an in-laboratory environment [24]. These models, however, are insensitive to the distribution of vehicles' instantaneous modal events, which are needed when network control strategies are to be developed.…”

Environmental pollution in Urban Transportation NetworksIn the past decades, extensive research efforts have been made in the area of urban environment striving to improve the urban air quality and address the challenges emerged from public health and the preservation of the entire ecological system. Transportation-related emissions are the dominant source of urban air pollution, and the second largest source of carbon dioxide (CO 2 ) emissions in the United States, which emitted approximately 27 percent of total U.S. greenhouse gas (GHG) emissions in 2015 (Figure 1). Transportation has also been the fastest-growing source of GHG emissions. From the pre-industrial era (i.e., ending about 1750) to 2015, concentrations of the greenhouse gases (CO 2 , CH 4 , and N 2 O) have increased globally by 44 percent, 162 percent, and 21 percent, respectively [1].The greenhouse gas (GHG) emissions primarily come from burning fossil fuel for all modes of transportation (vehicles, ships, trains, and planes) [2]. Petroleum based fuel took over 90 percent for transportation, including gasoline and diesel fuels. Most of the transportation related GHG emissions are carbon dioxide (CO 2 ) emissions resulting from the combustion of petroleum-based fuels. More than 50 percent of transportation related GHG emissions are from passenger vehicles, lightduty trucks, sport utility vehicles, pickup trucks, and minivans. Other portions of GHG emissions are from heavy-duty trucks, commercial aircraft, ships, boats, trains, pipelines, and lubricants.In addition to GHG emissions, transposition also makes contributions to important air pollutants (68.4 percent CO, 60 percent VOCs, 49.1 percent NO x , 5.5 percent particulates and 1.3 percent SO 2 ) [3][4][5]. Moreover, NO x is not only a primary air pollutant, but also accounted for the production of free radicals in troposphere, which can promptly react with VOCs and lead to a large variety of secondary air pollutants that could be much more hazardous to the public health than the primary air pollutants in urban environments [3][4][5]. Dirty air has been linked to cancer, asthma, stroke and heart disease, among other health issues. In UK, roughly 40,000 deaths each year can be attributable to outdoor air pollution [6,7]. Curbing vehicle emissions has become an increasingly important task in urban environment. Monitoring and Strategies to Reduce Transportation EmissionsIn response to these challenges, a range of emerging technologies are adopted to reduce transportation-related emissions on urban roadway networks. Existing traffic monitoring networks enable adaptive traffic AbstractThis article reviewed the impacts of vehicle emissions in urban transportation network, the existing strategies to reduce such transportation emissions, the complexity of urban transportation environment network, and the development of vehicle emission models. The vanguard research needs are also proposed in developing emission and air quality models and simulation, and emission-oriented transportation management strat...

“…Thus a variety of tests have been carried out to more carefully describe local conditions for driving. Driving cycles have recently been developed for Athens [5], Edinburgh [19], Hong Kong [16] and for eleven cities in China [15], for example, as well as a panEuropean project to describe a set of coherent driving cycles for Europe [13].…”

“…Recent research papers have reported on using manufacturers' proprietary software and interface systems in order to communicate with the test vehicles [6,19]. Such experimental arrangements have the advantage of being able to potentially communicate with a given make of vehicle, such as Ford or Renault as in the case of the cited studies.…”

“…Other researchers, using external measurement devices, have focused of vehicle speed and acceleration [16,17]. The ability to connect directly to the ECU has allowed other researchers [6,12,19] to examine certain engine operating characteristics such as engine speed, temperature and throttle position, as well as the parameters mentioned above. Connection to the OBD network of sensors also allows for determination of air-and fuel-flow parameters, in order to better estimate fuel consumption and emissions in near real-time [12].…”

With increased numbers of vehicles on Irish roads, there is now a need to be able to scientifically assess the quantity of pollutant material to which populations are exposed. Traditionally, emissions have been determined using kinematic (vehicle speed) data but recent studies have identified that other parameters are of interest. The work in this Paper focuses on the development and testing of a purpose-built software system to extract onboard diagnostic data from a vehicle in order to derive a driving cycle and to use other engine characteristic data to better inform local pollutant and energy consumption models for Dublin. Comparisons with GPS data shows the system to be cost effective (price and computing overhead) and reliable.
