“…Several authors have concluded that eco-route navigation has great potential for reducing fuel consumption [20][21][22][23]. However, this concept is somewhat complicated to implement, since the optimal speed profile for reducing fuel consumption and CO 2 emissions may produce an increase in some types of pollutants, such as CO and HC [24,25]. Ericsson et al [26] conclude that emissions could be reduced by around 8.2% by choosing an eco-route.…”

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 CO 2 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.

The safety evaluation of geometry features design based on actual driving behavior has always been a basic concept of highway design. However, current design methods, including both the design speed method and operating speed method, are still far away from real-world driving conditions. In this work, we propose a new alignment design method which can take into account typical handing patterns (driving styles) of human drivers and can pay special attention to dangerous driving behaviors. The core of the proposed method is forecasting the trajectories of typical direction control patterns within roadway width, which can be used by drivers. Then, forecast the driving speed of typical speed control patterns on the basis of the curvature of the preview trajectory just determined. Mathematical programming method was used in this study, whereby the objective functions and constraints were developed to model the typical driving patterns. This article provided five direction control patterns and four speed control patterns to designers so that they could select an appropriate pattern to predict the trajectory and speed for the designed road. Finally, the trajectory and speed are used to control the geometric features of the road. Geometric features can determine the driveway shape, such as curve radius, deflection angle, spiral length, tangent length, roadway/lane/shoulder width, and any or all of these can be adjusted by the designer. Meanwhile, as more than one driving pattern is optional and vehicle performance, driving stability, and ride comfort restrictions are introduced to trajectory/speed decision-making, the new method more closely approximates to real-world driving than conventional methods. The application example shows that the proposed method is especially suitable for the horizontal alignment design of low/medium design speed highways that traverse rugged terrain.

“…Regarding intercity routes, tests conducted during both the peak and the off-peak hours have shown that the faster routes can reduce CO 2 emissions by up to 30%. In a related research, Bandeira et al (2013) investigated a way to generate information about emissions for drivers faced with a choice of routes. According to their results, the choice of a route can substantially affect emission rates of the analyzed pollutants and that smoother driving styles can also result in considerable emissions reduction.…”
