In recent years, eco-driving has proven to be an effective tool for reducing fuel consumption and greenhouse gas (GHG) emissions. Until now, most research carried out has focused on ordinary drivers applying eco-driving techniques on their usual routes. However, there is little research on professional driver couriers. This research is aimed at analyzing the effects that eco-driving has on fuel consumption and GHG emissions on courier deliveries in small cities such as Caceres (Spain). For this purpose, a real-life experiment was performed with professional drivers with Spanish post vans from the public sector company Correos. In the first period, driving was under normal conditions (non-eco), and after a theoretical training eco-driving course, there was a second driving period (eco). Driving parameters (speeds, accelerations, rpm, and consumptions) were recorded on all trips to analyze how effective the eco-driving was. The research concluded that eco-driving training does not correlate with more sustainable driving for professional drivers under pressure with the need to deliver packages on time. However, there is a trend in fuel savings when using higher capacity routes.

CO2 emissions reduction is a top element of transport policy agenda. Among other mitigation policy measures, eco-driving techniques have proven to be effective in reducing fuel consumption and CO2 emissions. The aim of this paper is to compare the impacts of adopting eco-driving in different cities, road segments, traffic, and driver features. It intends to gain an insight into how city size and driving characteristics can reduce fuel consumption and CO2 emissions in order to develop specific eco-driving strategies. Field trials were conducted in two Spanish cities (Madrid and Caceres). 24 drivers, with different driving experiences, drove two different vehicles (petrol and diesel) along roads with different characteristics. The experiment was divided into two periods of 2 weeks; after the first one, drivers received an eco-driving training course. The impacts of eco-driving were measured comparing before and after results. They showed that eco-driving is highly effective in reducing fuel consumption and CO2 emissions in both, large-congested and small, cities. Savings between 5% and 12% were achieved. The efficiency increases with road capacity and decreased with city size. Eco-driving appears to be more effective in small, uncongested cities. In addition, limiting speeds on high capacity roads has proven to be a good energy saving measure.

This research aims to find the most ecological itineraries for urban mobility in a small city (eco-routes), where distances are rather short, but car dependence is really high. A real life citywide survey was carried out in the city of Caceres (Spain) with almost 100,000 inhabitants. Research was done on alternating routes, traffic, times of day, and weather conditions. The output of the study was to assess fuel consumption, CO2, and regulated pollutant emissions for different type of vehicles, routes, and drivers. The results show that in the case studied, urban roads had fewer emissions (CO2 and pollutants) but there was an increase in the population affected by pollutants. On the contrary, bypasses reduced travel time and congestion but increased fuel consumption and emissions. Traffic conditions had a greater influence on fuel consumption in petrol vehicles than diesel ones. Therefore, there must be a balanced distribution of traffic in order to minimize congestion, and at the same time to reduce emissions and the number of people affected by harmful pollution levels. There should be a combination of regulatory measures in traffic policies in order to achieve that balance by controlling access to city centres, limiting parking spaces, pedestrianization, and lowering traffic speeds in sensitive areas.

La Administración Pública y el promotor privado buscan tener un conocimiento previo de los costes de cualquier edificación. Existen en la literatura numerosas metodologías que permiten realizar la valoración de un inmueble, pero siempre se ha realizado para viviendas urbanas en ciudades grandes o medianas. Esta investigación propone el uso de Inteligencia Artificial para el estudio de viviendas rústicas en pequeñas ciudades como la de Cáceres (España). La investigación propone un procedimiento de Redes Neuronales Artificiales (RNA) para conseguir por un lado estimar a través de un método automático el coste de construcción de la vivienda rústica y por otro, identificar los atributos más determinantes en su precio final. La RNA diseñada establece como variables más influyentes en el precio final del inmueble los espacios húmedos (baños y cocina), la superficie construida y la antigüedad por este orden, diferenciándose de las variables más determinantes en el precio de las viviendas urbanas en grandes o medianas ciudades que son la superficie construida y su ubicación.

The transportation sector is one of the largest emitters of greenhouse gases. Eco-driving has been shown to be a very efficient driving technique to reduce consumption and CO2 emissions into the atmosphere. Specifically, this paper investigates, based on the psychological characteristics and perception of the driver, the variation in different fundamental parameters of driving when driving conventionally with respect to an eco-driving. This research has been carried out on four types of routes and different levels of service in a small city with no congestion problems, such as the city of Caceres. Drivers are men and women in an age range of 21 and 44, driving diesel and gasoline cars, a first week with normal driving and the second after having received an efficient driving training course. This research concludes that eco-driving reduces the fundamental parameters of driving in a conventional style in all types of drivers, with a greater reduction in those with less experience in years of driving. Therefore it would be advisable to establish eco-driving policies in the driving schools since implementing these measures in novice drivers is easier and more efficient than in experienced drivers

Small cities with less than 200,000 inhabitants do not usually suffer from chronic congestion problems. However, private vehicles are used excessively, making it necessary to implement measures to encourage further use of public transport and pedestrian mobility to make it more sustainable. Bypasses improve level of service (LOS) by removing cars from the city center, leading to significant reductions in overall travel time. Most studies so far have been conducted in large cities suffering chronic congestion problems, so the aim of this research is to analyze the effects of bypasses in small and non-congested cities through the construction of a traffic model in Badajoz (Spain), starting with the allocation of the origin-destination travel matrix derived from surveys and traffic counts conducted at the southern and eastern accesses. The traffic model describes the mobility in potentially-capturable future southern traffic relationships and allows insights into different alternatives in the construction of a new high LOS road. This research concludes that small cities with no chronic congestion problems should plan bypasses as close as possible to the city, since they are the most economical, produce greater traffic capture, greater time savings, and eliminate the largest number of CO2 emissions from the urban center. The more distant alternatives have a higher LOS, however, these are longer and more expensive solutions that also capture less traffic and thus eliminate less CO2 emissions.

Despite technological advances in engines and fuels, the transportation sector is still one of the largest emitters of greenhouse gas (GHG). Driving patterns, including eco-driving techniques, are a complementary measure for saving GHG emissions. Most eco-driving studies so far have been conducted in large cities suffering chronic congestion problems. The aim of this research is therefore to analyse the potential of driver behaviour for reducing emissions in a small non-congested city. Driver performance parameters such as travel speeds, number of stops, revolutions per minute, and maximum acceleration-deceleration are also studied. The methodology is designed to measure the effect of both eco-driving and eco-routing under real traffic conditions. A campaign was carried out in the city of Caceres (Spain) to collect data on various types of roads under different traffic conditions. This research concludes that eco-driving leads to CO2 savings on all routes and road types of 17% in gasoline engines and 21% in diesel, although travel times are increased by 7.5% on average. The shortest route is also the most ecological, regardless of the traffic volume and characteristics, implying that consumption in non-congested cities depends mainly on distance travelled rather than driving patterns in terms of number of stops, speed and acceleration.

This paper describes the methodology used for the construction of a traffic model in Badajoz (Spain) starting with the allocation of the origin-destination travel matrix derived from surveys and traffic counts conducted in the southern and eastern accesses of Badajoz. The traffic model describes the mobility in potentially-captable future southern traffic relationships and allows the calculation of savings in travelled distance and travel times on the current situation. The traffic model allows to know different behaviours of the possible alternatives in the construction of a new high-capacity road. The model is able to select the one which captures more traffic and produces a bigger saving in travel time, meaning, the one which produces a better socioeconomic improvement. The research concludes in favour of the nearest corridor to the city centre, being this one the more crowded and the one that produces greater time savings. It is also the corridor that allows giving the Southern Bypass a dual purpose of collectingdistributing in the city of Badajoz.
