13 5. The Impact of the Project - Results 5.1. Technical Performance All new equipment installed has worked properly after the calibration and adjustment process. It has been assured the full system operability at the evaluation time Results Results are indicated as follows: - From the safety point of view, as it is reflected in the following table, it is showed the accident evolution among 2010 and 2011 in the specified segments (A-7 kp (Benalmádena Málaga) and MA-21 kp 0-5) ACCIDENTS YEAR ROAD KP ACCIDENT NUMBER WITH SLIGHTY FATALITIES/INJURED FATALITIES INJURED INJURED 2010 A MA A-7 / MA MA Almost 26% accident reduction has been achieved in A-7 evaluated segment with a significant fatalities reduction (83%). Regarding MA-21, although the number of accidents has slightly increased (33%), the fatalities are the same in the compared period. It is expected to study deeper the reasons because of this fact happens. When analyzing similar data split per departments under the management of the related TCC, it is kept the data homogeneity and it is observed an improvement (reduction) of accident number in all departments (10.3% in the best case) although there are two departments (Almería and Granada) which increase number of fatalities and injured people. It should be also analyzed in depth how this statistics could be improved.

14 - From the congestion point of view: As it is reflected in the following table, the evolution is positive in congestion reduction from 2010 to A-7 Benalmádena Málaga Segment Traffic Jam Year Number Almost 65,2% has decreased the congestion in the analyzed segment which proves that all the equipment deployed eases and helps to manage efficiently the traffic movement. To complete this analysis it has also been studied all the departments under the management of the related TCC in the same period. Department Traffic Jam Number Year 2010 Traffic Jam Number Year 2011 Almería Granada Jaén Málaga Total It has also been reduced slightly the traffic jam numbers, almost a 44,9% less congestion. It is worth mentioning Málaga area since due to the new west and north axis, the congestion has been reduced almost 62%. This general result (incident and traffic jam reduction) implies also a travel time saving which can be related (although not verified) with a pollution decreasing Reliability of Results All these results and conclusions have been achieved from the database which contains all data related to traffic issues. As it can be consulted in the Annexes, it has been selected two periods of time in order to compare all data got before the installation of ITS new infrastructure and after the installation. With a very simple statistical process it has been possible to reach the conclusions. The accuracy is high since the data are real with a very low error margin Overall Assessment It is a fact that the new ITS equipment installed in the studied segment has contributed to improve efficiency to adopt better traffic management decisions and to ease the road user his/her travel since the information showed is accurate and clear. It also contributes to improve the safety and the benefits in the environment are collateral because of the reduction of traffic jams. 11/07/ Information via VMS. A-7 Segment (Malaga Benalmádena)
