Numerous sensing technologies tackle the challenging problems of traffic-monitoring infrastructure, including intersection control, speed tracking, vehicle counting and collision prevention. TI’s 77 GHz millimeter-wave (mmWave) radio-frequency complementary metal-oxide semiconductor (RF-CMOS) technology and resulting mmWave sensors have inherent advantages with respect to environmental insensitivity/ robustness, range and velocity accuracy and system integration. TI’s simplified hardware and software offerings—including evaluation module (EVM) references, reference designs in the TI Designs reference design library, software libraries and code examples—make mmWave sensing technology truly accessible and enable you to quickly evaluate and demonstrate its capability in an application.
Transportation systems are an important component of the infrastructure necessary to move individuals and freight quickly, efficiently and safely around the world. These pieces of infrastructure focus on sensing conditions around trafficked areas and collecting data that can help the infrastructure react to changes. Traffic engineers use the data to build statistics and help target future infrastructure investments, while drivers use the data to help manage their routes. The value of this information is obvious, since the intelligent transportation systems market is forecasted to reach more than US $63.6 billion by 2022.
mmWave sensing technology detects vehicles such as cars, motorcycles and bicycles, at extended ranges regardless of environmental conditions such as rain, fog or dust. TI’s mmWave-sensing devices integrate a 76–81 GHz mmWave radar front end with ARM® microcontroller (MCU) and TI digital signal processor (DSP) cores for single chip systems. These integrated devices enable a system to measure the range, velocity and angle of objects while incorporating advanced algorithms for object tracking, classification or application-specific functions.
