The alarm system for vehicles is commonly used to expose the burglars publicly to make a scene. If the vehicle owner is far away, it will be hard to distinguish the threat to the vehicle from the intruder. To deter such crime, there should be a safer pro- tection mechanism for vehicles around the globe. Moreover, overcrowd parking lot problems have always been an issue. Nevertheless, it became even worse with the progressing urbanization and population expansion. Anyone may have experienced that moment of panic when you realize you have no idea where you parked your vehicle. Note that, the keyless remote control of vehicles has a short-range radio transmitter. It usually can reach up 5–20 meters. Therefore, this paper develops a proposed system that is used for detecting vehicle location using Global System for Mobile Communications (GSM). It is basically capa- ble to switch ON and OFF vehicle alarm system to detect the location of the ve- hicle in a crowded area. PIC microcontroller that has been embedded in the sys- tem programmed using C language. The intelligent proposed system also de- signs to enhance the security feature for the transportation era. The proposed system offers better service and cost-effective for the vehicle owners.

Increased number of ve- hicles on the road continuously confirmed intelligent transport systems are inevitable. Recently, the automotive manufacturers companies are working and competing to- gether with substantial technology organizations to deliver the most exceptional, most comfortable, and most secure vehicles on the market. The existing vehicle alarm sys- tems have lock and alarm employed within vehicle. If a thief can manage to pick the lock, then it becomes easy for the thief to stop the alarm and steal the vehicle without the vehicle owner’s knowledge. To avoid such situations, there must be a better secu- rity system for the vehicle. Global System for Mobile Communications (GSM) and Short Message Service (SMS) technologies are frequently utilized for wireless data transmission [1-3]. The iJIM ‒ Vol. 15, No. 04, 2021 85
