    after the braking action the pace car accelerates back to 100 km h see camera 12 The shock caused by this action is clearly evident among the braking cars following Also clearly evident is that the effect of the shock lasts some time because the vehicles take longer to accelerate than they do to brake This is consistent with the Japanese film in which a shockwave is shown A range of braking actions is used to create an optimal shockwave to top Results To determine the improvement in traffic flow four aspects were analysed namely Traffic intensity Finish line Density Time headway Below the following film is used to explain each aspect in detail JavaScript is uitgezet Om de content af te beelden heb je een browser nodig die JavaScript ondersteunt Adobe Flash Player niet geinstalleerd of ouder dan 9 0 115 The film shows a scenario in which the group of vehicles fitted with the advisory system grey and the reference group red are visible The pace car travelling upfront is emphasised by means of the colour blue and a circle The pace car performs two braking actions which result ultimately in a shockwave that travels through the following vehicles Traffic intensity The traffic intensity is the number of vehicles that travels over a section of road per hour An improvement in the traffic intensity means that in total more vehicles can travel over that section of highway thereby increasing traffic flow On average the traffic intensity of the group of vehicles with communication is 12 higher than in the original situation There are even spikes of up to 25 Thus sizeable differences are evident in the area of traffic intensity At present research is continuing into how we can further increase this traffic intensity Finish line As well as the traffic intensity a finish line scenario was also analysed An imaginary finish line was positioned alongside the last camera Level with this camera the advantage of the group of vehicles with advisory system was determined compared to the reference group the group of vehicles without the system Averaged out across all three trips the equipped group achieved an advantage of more than three vehicles at the last camera Once again there were spikes of up to seven vehicles advantage among the vehicles equipped with communication Density The traffic density is the number of vehicles per kilometre per lane The density is determined by the distance between two vehicles otherwise referred to as the distance headway maintained by drivers The closer vehicles drive to one another the higher the traffic density Density and traffic intensity depend greatly on the driving speed at higher speeds drivers will be inclined to increase their distance headway This has the effect of reducing the density of the group of vehicles When the weight of traffic increases drivers are inclined to drive closer together and their speed necessarily decreases Figure 2 shows the average density compared to the average speed for all experiments Fig
