The evaluation was based on traffic monitoring indicators, measuring the change in red light, public transport lane and speed infringements and surveys, measuring public awareness and acceptance of the implemented system.
The key results were as follows:
• Red light infringements decreased significantly – The number of red light infringements dropped 9,5 times, from 0,95% to 0,1%;
• PT lane infringements decreased significantly – The number of PT lane infringements dropped 4,4 times, from 7,95% to 2,2%;
• The level of speed infringements after the implementation was low – only 0,3% of drivers passing the two cross-sections were exceeding the speed limit;
• The awareness was increased – the awareness of the enforcement cameras increased from 50% to 62%;
• The acceptance was decreased – the acceptance of the enforcement cameras decreased from 82% to 77%.
The most important barrier encountered during the measure was: High legal demands on the enforcement system. This made the preparation of the system and the procurement very complicated and time-consuming.
The most important driver encountered during the measure was: Common understanding on the importance and the need for the measure between all involved partners. All discussions were focused on the details and results of the measure, not the usefulness of the measure.
The most important activity – Due to the need for a general understanding of the system, many meetings were organised to include all partners involved in the implementation of the measure.
Recommendations for measure replication:
• Traffic enforcement system 3 in 1 – The measure is replicable for cities that need to capture 3 different types of traffic infringements by the same enforcement camera;
• System with high judicial reliability – the fines for traffic infringements are issued automatically but in the case of an appeal by drivers there is always strong evidence available for each infringement in the form of pictures.
Recommendations for process:
• Need for specific competence: implementation of the enforcement system requires specific knowledge about legislation and technical specifications.
• Too many different partners for a pilot project: measures in the CIVITAS initiative have limited time for implementation (4 years). When many partners are involved in the preparation and operation phase, it may present a risk for the implementation timetable.
• Early start is crucial: this measure should have been the first to begin at the start of the MIMOSA project, at least by the end of 2009. With so many important partners involved and a complicated legislative process the arrangement of the procurement takes years.
