Emissions from motor vehicles are the primary cause of deterioration of urban air quality. Altering driver behavior can potentially contribute to the reduction of emissions and pollutants. Previous studies revealed that unnecessary acceleration and hard braking inresponse to sudden changes of traffic signals causes significant wasted energy.  Providing drivers with advance information about traffic signal status can potentially result in modifications of driving behavior so that drivers will exhibit smoother driving profiles. These smoother profiles provide benefits particularly by reducing hard braking in front of intersections when the green signal phase ends. This paper, through both analysis and simulation, investigates the potential benefits on emissions and energy consumption of making traffic signal status information available to drivers. Safety benefits of this approach are also discussed.

Urban development is  worldwide facing severe socio-economic challenges. On the one hand,
mobility demand is still increasing bringing economic wealth, on the other hand, residents and
tourists want policy makers to set up “Green High Tech Districts“  with excellent subway
systems and bicycle lanes to attract more visitors and consumers. Tourism and cheap airlines
started to boost global competition among cities for more international visitors, so modern
cities have to balance increasing mobility requirements and environmental standards – a
difficult task for transport policy.

Toyota City has established the “eco-driving declaration system” to create an environment for
a majority of its citizens to launch ecology-conscious driving. This paper reports on the
effect of the practice and study of measures to promote dissemination of further
ecology-conscious driving.

This paper considers how ITS can be harnessed to reduce harmful emissions and therefore
enhance air quality and reduce the effect on climate change from CO2. It does so from two
angles; firstly it considers the benefits that can be achieved by managing and reducing highway
congestion through the use of technology based systems, and secondly, it considers the balance in carbon use between the building and operating of traffic congestion management schemes and the resultant reduction in emissions from traffic. The CO2 produced when constructing, operating and decommissioning technology schemes is often overlooked. To determine the true impact that an ITS scheme has on CO2 emissions it is essential to quantify both the benefits and dis-benefits over the life of the scheme. This is illustrated with a case study of the UK M25 J15 to 16 Variable Mandatory Speed Limit (VMSL) Scheme. Whilst the calculations relate to the specific example (M25 VMSL) the principals can be adopted, and further refined, for other ITS schemes.

EcoDriving is a style of driving which will help you to save both money and the
environment. The method can be applied to every kind of vehicle, and at present there are
four concepts each focusing on different types of vehicle.
• EcoDriving for motorcars
• Heavy EcoDriving for heavy motor vehicles
• Working EcoDriving for utility vehicles
• EcoDriving Rail for railroad engines
The concept of EcoDriving was brought to Sweden by Swedish National Association of
Driving Schools (STR) in 1998, and was developed and adapted to Swedish conditions in
collaboration with public authorities and business companies.
With EcoDriving we know it is a quantifiable success. We began work of the concept of
EcoDriving more than 10 years ago. With more than 50,000 drivers properly trained,
motivated, supervised and incentivized we have the data to prove it is more than a fad; it is a
permanent lifestyle change with positive impact on the Environment, Economy, Corporate
bottom line and Individual quality of life.
