Smart traffic systems already contribute to solving many road transport issues, be it in terms of safety at traffic lights or speed limits – or when it comes to restricting certain areas or lanes to specific road user groups. Moreover, with respect to the growing interconnectedness of systems with the further digitalisation of road monitoring, modern ITS is a prerequisite for smart city solutions, enabling safer roads and less air pollution through constant traffic flow, making city life safer and easier.
Mobility is a basic need in our modern society. Even in densely populated cities and metropolitan areas, individual mobility in a car remains a popular means of transport which also provides protection from personal encounters with strangers such as on public transport – a fact that must be highlighted in times of a global pandemic. Road protection, safe mobility and security matters play an important role to maintain and improve the effectiveness of road traffic. All these aspects can nowadays be controlled, enforced and connected by the latest generation of intelligent traffic cameras.
Metropolitan areas will continue to attract more people in the years to come and, with this, road traffic will increase in density. As such, control and limitation of individual traffic is one measure of many communities to manage traffic flow and quality of life in densely populated areas. In the recent past many cities have established limited traffic zones (LTZ) and congestion charges which help reduce traffic jams and air pollution in a bid to improve quality of life. These zones need to be monitored and tolls need to be charged.
Data gathered from smart traffic cameras can be used here to continuously identify the vehicle and recognise the number plate which enables authorities to automatically charge the owner for entering the LTZ. Another tool to control traffic flow in dense urban areas is prioritising traffic lanes for vehicles which carry more than one passenger, be it buses, taxis or private cars containing several people. This also needs to be constantly monitored with efficient smart camera technology to guarantee that only designated vehicles use priority lanes – and to allow for sanctions on unauthorised lane use.
Maintaining and enforcing smooth coexistence in dense road traffic requires smart tools to monitor compliance with traffic rules by all road users. Traffic lights belong to the most critical areas that need to be monitored. An efficient way to perform red light violation enforcement is the installation of permanent smart cameras on such critical scenes – such as the Tattile Smart TL2L traffic light, which automatically detects light status using camera-based image analysis.
Every time a light turns red, the violation mode activates and the system creates a virtual trigger on the road surface. Once a vehicle crosses this virtual line causing a violation, the intelligent camera takes a picture of the licence plate, which is then used to create a detailed evidence report.
