Derived from the population increase and urban growth, vehicle traffic has increased in the cities of Colima and Villa de Álvarez located in Mexico, and with it the problems of road safety and traffic management; the increasing number of roads and traffic lights implies recording the information of each one of these; Therefore, this article presents an information system for the management of intelligent traffic light infrastructure. In the software engineering process, the Agile Unified Process was used to manage the main risks early and guarantee the quality of the product during its life cycle. The system was tested at a prototype level with satisfactory results, as a result a web system contributes to improving road and citizen safety, since based on two vehicle data it connects with web services to other databases, and identifies Immediately form the incidents of vehicles that pass through the roads, including stolen vehicle, speeding and a panic button. The expectations are to scale it to the real environment, and make available to the corresponding authorities the information collected to favor decision-making.

Objective: To describe the systematization of the Nile tilapia cultivation process using a computer system for production and marketing traceability based on ISO 12877:2011 standard and web technologies. Design/methodology/approach: A documentary and field investigation were conducted to learn about the Nile tilapia production process currently applied; traceability was evaluated based on Double T and María del Carmen study cases, aquaculture farms located in the municipalities of Manzanillo and Armería located in the state of Colima, México; the process was contrasted with the ISO standard and the system was developed and implemented. Results: A Traceability System that records backward, internal, and forward procedural activities in the cultivation and marketing of tilapia. The system improves food safety control by registering lot care based on the ISO standard, resulting in well-defined traceable processes in the production and commercialization of the Nilotic tilapia. Limitations on study/implications: The results shown are related to the development and implementation of the system; however future work is yet to be carried out to assess its effect on the production and commercialization of farmed tilapia, as well as the efficiency of traceability. Findings/conclusions: The system was developed taking into consideration the necessary indicators for an ISO certification. Hence, aside from simplifying the registration and consultation of information, the producing company has the benefit of earning a certification for the aquaculture production process, creating additional value to its products.
