In metro cities, cars are not allowed to exceed the displayed speed limit. However, many drivers still choose to speed, which is a major contributing factor to accidents. To address this issue, an easy-to-use road speed check system has been implemented to automatically detect traffic crashes in smart cities. This system uses a photovoltaic (PV) input power supply source, which captures the light emitted by the sun on solar panels and converts it into energy. In addition, the system utilizes an IR sensor to measure the speed of vehicles by detecting their distance and time. The infrared sensor detects a car in front of it, allowing for the calculation of time. A proximity sensor is also used to detect the speed of vehicles, regardless of their material configuration. The ESP8266 interface camera is used to capture live images in traffic, which are then transmitted to a specific IP address. Furthermore, the GSM Communication Device allows for the transmission of vehicle speed information through digital cellular communications, such as GSM (Global System for Mobile Communications). The output of this system accurately reflects real-world traffic data and has been tested through a comparison examination of individual speed measurements
