Driving Behaviour and Sustainable Mobility—Policies and Approaches Revisited

Climate change is receiving increasing attention in recent years. The transportation sector contributes substantially to increased fuel consumption, greenhouse gas (GHG) emissions, and poor air quality, which imposes a serious respiratory health hazard. Road transport has made a significant contribution to this effect. Consequently, many countries have attempted to mitigate climate change using various strategies. This study analysed and compared the number of policies and other approaches necessary to achieve reduced fuel consumption and carbon emission. Frequency aggregation indicates that the mitigation policies associated with driving behaviours adopted to curtail this consumption and decrease hazardous emissions, as well as a safety enhancement. Furthermore, car-sharing/carpooling was the least investigated approach to establish its influence on mitigation of climate change. Additionally, the influence of such driving behaviours as acceleration/deceleration and the compliance to speed limits on each approach was discussed. Other driving behaviours, such as gear shifting, compliance to traffic laws, choice of route, and idling and braking style, were also discussed. Likewise, the influence of aggression, anxiety, and motivation on driving behaviour of motorists was highlighted. The research determined that driving behaviours can lead to new adaptive driving behaviours and, thus, cause a significant decrease of vehicle fuel consumption and CO 2 emissions.

Green Driver: Travel Behaviors Revisited on Fuel Saving and Less Emission

Road transportation is the main energy consumer and major contributor of ever-increasing hazardous emissions. Transportation professionals have raised the idea of applying the green concept in various areas of transportation, including green highways, green vehicles and transit-oriented designs, to tackle the negative impact of road transportation. This research generated a new dimension called the green driver to remediate urgently the existing driving assessment models that have intensified emissions and energy consumption. In this regard, this study aimed to establish the green driver's behaviors related to fuel saving and emission reduction. The study has two phases. Phase one involves investigating the driving behaviors influencing fuel saving and emission reduction through a systematic literature review and content analysis, which identified twenty-one variables classified into four clusters. These clusters included the following: (i) FE f1 , which is driving style; (ii) FE f2 , which is driving behavior associated with vehicle transmission; (iii) FE f3 , which is driving behavior associated with road design and traffic rules; and (iv) FE f4 , which is driving behavior associated with vehicle operational characteristics. The second phase involves validating phase one findings by applying the Grounded Group Decision Making (GGDM) method. The results of GGDM have established seventeen green driving behaviors. The study conducted the Green Value (GV) analysis for each green behavior on fuel saving and emission reduction. The study found that aggressive driving (GV = 0.16) interferes with the association between fuel consumption, emission and driver's personalities. The research concludes that driver's personalities (including physical, psychological and psychosocial characteristics) have to be integrated for advanced in-vehicle driver assistance system and particularly, for green driving accreditation.

Review of Driving Behavior Towards Fuel Consumption and Road Safety

2018

One of the main concerns for automobile researchers is establish a driving method that is efficient to the engine and ensures road safety. Most studies categorized driver’s behavior based on aggressiveness while driving. It was found that aggressive drivers tend to provoke fast start and quick acceleration, driving at high engine revolution, and causing sudden speed change that are prone to road accidents. On the other hand, eco-driving which consists of gentle acceleration, coast-down deceleration, maintaining a steady speed and avoidance of high speed is much safer than the aggressive driving. At the same time smooth, experienced pattern in the eco-driving consumes lesser fuel in a statistically significant way. Driver’s aid system in modern cars have been invented to assist the driver into eco-driving were claimed to be effective. However, in the absence or failure of such system, drivers are suggested to drive by maintaining steady speed, avoiding sudden stop and harsh accelerat...

Eco-driving: behavioural pattern change in Polish passenger vehicle drivers

E3S Web of Conferences, 2018

In Poland, as in the rest of Europe, air quality depends primarily on emissions from municipal, domestic and road transport sources. The problems of appropriate air quality are especially important within urban areas due to numerous sources of emissions being concentrated in relatively small spaces in both large cities and small/medium-sized towns. Due to the steadily increasing share of urban population in the overall number of population, the issue of providing clean air will over the years become a more significant problem for human health, and therefore a stronger incentive to intensify research. The key challenge faced by a modern society is, therefore, to limit harmful substance emissions in order to minimise the contribution of transport to pollution and health hazards. Increasingly stringent emission standards are being imposed on car manufacturers; on the other hand, scant regard is paid to the issue of drivers, i.e. how they can help reduce emissions and protect their life...

Driving style and traffic measures-influence on vehicle emissions and fuel consumption

Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2004

This paper describes the influence on vehicle emissions and energy consumption of different vehicle parameters and driving style as well as of traffic measures taken in order to increase transport safety or to reduce traffic jams. This should allow the Flemish Regional Government to perform more realistic modelling of the impact of transport on air pollution. The methodology is based on on-road measurements, roll-bench emission tests, vehicle simulations and regional emission modelling (for the Flemish Region, which encompasses the northern part of Belgium and is one of three entities that constitute the Federal Kingdom of Belgium). A vehicle simulation programme (VSP) has assisted in the assessment of the individual vehicle parameters (weight, gear shifts, tyre pressure, etc.). Different drive styles (sportive, EcoDriving, etc.) were measured on-road and evaluated on a roll-bench. Typical speed profiles corresponding to different traffic measures such as roundabouts, phased traffic...

Promoting Sustainable Mobility Through Car Use Reduction: The Importance of Situational Factors

Journal of Sustainability Science and Management, 2020

Rising car ownership and use worldwide is in several respects a threat to the environment. Transport researchers and policymakers have suggested and implemented policy measures to reduce car use and encouraged pro-environmental travel behaviour. The success or failure of these policies depends on a robust understanding of the factors influencing car use behaviour and most importantly situational factors facilitating car use. A sound understanding of the situational factors is the key to the effectiveness and success of car use reduction policies. This study examines the importance of car use facilitating situational factors in the promotion of sustainable mobility in urban areas. Data were obtained in a cross-sectional survey of 691 motorists in Lagos, Nigeria through purposive sampling technique, while the data analysis was done using partial least square structural equation modelling (PLS-SEM). The results indicated car access, time pressure and car use intention contributed 43% e...

DRIVERS' ADAPTIVE TRAVEL BEHAVIORS TOWARDS GREEN TRANSPORTATION DEVELOPMENT: A CRITICAL REVIEW

The transportation professionals integrated the concept Green in various dimensions of transportation, such as, green vehicle, green highway. The current study has established a new dimension to green transportation, which is called Green Driver as whom substantially contributes to less emission and fuel consumption, and higher-safety. The research established the driver's Green Adaptive Travel Behaviors (GATB), in particular, that is referred to voluntary personal and lifestyle behaviors on less energy consumption and emission. The methodology was designed into two phases. Phase one was to investigate driver's GATBs through systematic literature review process and content analysis method. The second phase was to verify greenery value impact (GVI) of the finalized list of drivers' GATBs through an expert input study and Grounded Group Decision Making (GGDM) method. Total twenty six (26) GATB factors have been determined. Amongst, the factor 'F27-Dangerous overtaking' has received the highest value (97%) followed with 'F3-Slow once realizing bike lanes for cyclist crossing' (91%). In contrast, 'F4-Realize visual Obstacles to manage the speed' and 'F21-Brake with smooth deceleration' has received the lowest value (77%) among other factors. Two of the initial factors;'F5-Use traffic calming devices' (55%), and 'F24-Change highest possible gear' (69%) could not reach the 70% saturation; hence, they have been dropped from the list of GATB factors. Indeed, the GATB efforts are not limited to technology and practice; but also can include education and enforcement to driving regulations in order to interconnect driver, technology, environment, and vehicle. The research concluded with an innovative technique used as the decision support tool to evaluate the greenery grade of any individual driver on committing to less emission, less fuel consumption, and higher safety in traveling. As future study, the Green driver behaviour index assessment model will be developed based on this study outputs.

A Study on Eco – Driving Behaviour Of Passenger Car Users In Chennai

Auto industry is one of the fastest growing industries of the world. India is producing one out of every ten automobile made in the world. Auto industry is responsible for 15-20% of global carbon dioxide emissions and 80% becomes users’ responsibility (JAMA). Many people are aware of the world’s environmental issues and various countries had organized campaign to make people aware of this concept. The rising cost of fuel has brought the need to save fuel. Drivers do not realize the amount of influence their driving style has on fuel consumption, potentially leading to significant unnecessary emissions and increased fuel cost. Therefore there is a need to understand the car users’ eco-driving behaviour. The primary data was collected from 400 passenger car users of Chennai, India with the help of a structured questionnaire. The independent sample t test and descriptive analysis was performed and it is found that the driving behaviour depends on their gender, age, marital status and size of the vehicle but in other hand education and income did not had that much impact on their driving behaviour. Therefore the government and local authorities need to push awareness of ecodriving among the passenger car users.
