Capture, Analyze and Guide Traffic Flows:
Privacy-Compliant Road Management
Almost one million kilometers of traffic jams per year in Germany alone and around 30 years of valuable time lost by motorists: It is undisputed that a traffic turnaround is urgently needed. This is the only way to prevent cities and conurbations from collapsing, not to mention the ecological consequences and waste of resources. Nevertheless, the importance of individual mobility is enormous. Achieving this balancing act requires smart technologies and so-called Cooperative Intelligent Transportation Systems (C-ITS), which enable vehicles to be networked with each other and with the infrastructure. In addition, this enables comprehensive traffic statistics to be collected and utilized in real time.
Safe and Efficient: LPR-Based Travel Time Measurement With Route Mapping
License Plate Recognition - LPR for short - provides the perfect data for this. The use of time stamps and license plate data recorded by LPR sensors, as well as additional information, for example on vehicle type, make and model, makes it possible to collect comprehensive data on the actual traffic situation. However, this procedure is subject to stringent data protection requirements. They can be fulfilled, when intelligent LPR sensors reliably record the license plates of all passing vehicles and then encrypt the sensitive data directly and immediately on the edge device using a hashing process with a unique, non-reversible identifier. This ensures that the data is stored and processed completely anonymously.
CARRIDA 4.8 Supports Hashing and MQTT
CARRIDA has therefore implemented a hashing process in the latest version of its LPR software engine . The processing, i.e. the reading of license plates and the recognition of vehicle type and category, takes place directly on the smart sensor, so that only small amounts of data need to be stored or transmitted.
With a network of such smart traffic sensors, travel time measurements for individual vehicles can be performed between two or more sensors. Especially for this, CARRIDA supports MQTT for publishing reading results and images. The protocol enables connection to additional IoT devices and integration into networks. Only with this functionality, a system for path time measurement can be configured from several LPR sensors or the LPR data can be integrated into complex overall systems. To further improve data security, public key authentication for FTP actions and certificate-based authentication for HTTP data transmission are implemented.
LPR For Smart City, Toll Collection, Parking and Law Enforcement
The possibilities and application areas of LPR technology and intelligent vehicle-to-vehicle and vehicle-to-infrastructure communication solutions are not limited to the collection of traffic statistics: LPR and time-stamp recording can be used to detect and process routes taken by individual vehicles, for example, for fully automated calculation of a route toll or to calculate average speed for law enforcement applications. Artificial intelligence and Big Data analyses additionally help to observe trends and developments and to initiate appropriate measures for traffic planning and management.
Countless Applications - Current and Future
With LPR and hashed license plate data, it is possible to intelligently monitor roads . At the same time, identifying vehicles by license plate allows access to restricted roads or areas. License Plate Recognition can also be used to find, share and manage parking spaces , with booking of a parking space for a specific time and checking whether the registered vehicle is parked there. Or, as in the case of APCOA PARKING, to enable ticketless access to parking facilities using CARRIDA's technologies . In addition, numerous other applications are conceivable or have already been implemented, from smart speed displays with insertion of the recognized license plate to gratifications for particularly environmentally friendly driving behavior, etc.
Easy Integration on Any Device
CARRIDA offers the LPR library as software for easy integration into any stationary or mobile device. It can be implemented easily, quickly and cost-effectively and supports all common camera types. It can be installed and used on PCs running Windows or Linux as well as on ARM-based devices and mobile devices running Linux and Android. The software recognizes license plates from all countries and can thus be utilized worldwide.

Completely Ready to Use
CARRIDA also offers the software in combination with a specially developed and directly ready-to-use LPR sensor or as a construction kit for individual devices. The CARRIDA CAM Dragon+ / Basic+ is ultra-compact, can be installed and configured quickly and easily and is offered in two equipment variants depending on the required functionality. The robust sensor is available for different detection ranges and is ideally suited for outdoor use thanks to the IP67-protected housing and integrated heating. Data acquisition and processing as well as license plate identification take place entirely on the edge, with no further external computing unit required.
