However, plans to overcome the lack of parking lots have not yet promoted efficiency. Therefore, application of Smart for parking lots is completely necessary, when traditional parking lots cannot meet the increasing demand for vehicles today.
In addition, it is also impossible not to mention the remarkable role of Smart parking lots. This is a network connecting devices together, in which devices can transmit information and data with each other without human intervention. Moreover, we apply machine vision in identifying vehicle license plates and available places, then transfer data to our website to be able to easily control and help customers to capture the status of the parking lot. Besides, we also encountered many difficulties in the idea and deploying a smart parking lot.
First, it can be mentioned as the process of collecting data on license plates so that the system can learn and identify Vietnam's license plates. Second, it is a challenge for us to design a website and send data to it, as we take a lot of time to be able to build a website and transmit data as well as information up completely. Finally, the system is almost complete when it is possible to identify and analyze the number of license plates, count the remaining space up to 90% and transfer data to the website correctly. Overview of traffic situation in Vietnam In metropolises, the large population entails that the moving needs of the people increases and directly increases individual vehicles.
City managers should solve some issues about flow traffic so that it minimizes traffic jams in peak hours, building additional infrastructure such as highways, undergrounds, expanding additional routes to meet the density of vehicles, and developing a lot of parking lots to serve the demand for residents. For instance, in some large cities of our country today, like Ho Chi Minh City, finding a parking lot in the city center is very difficult, because the car traffic daily in the city is always a lot bigger compared to the number of built-in parking lots. So, it is difficult for users to find a parking lot to send their vehicles. Traffic congestion in metropolises on peak hours (Source: https://www.com/transport/traffic-jams.html) Not only that, the lack of measures to develop static traffic in the city has contributed to slowing the progress of building new parking lots.
Besides, plans to overcome the lack of parking lots have not yet been effective because investors have not seen their potential. Currently, the condition of parking lots is gradually becoming a problem in big cities in our country on Tet holidays and as usual. Meanwhile, there are also a lot of spontaneous parking lots with the aim of profit from people's car deposits but does not guarantee security, quality management and especially making ticket prices very 2 expensive, making many parts of people dissatisfied. So, the demand for smart and safe parking now is currently extremely large.
The vacant lands become temporary parking, significantly affecting urban beauty. (Source: https://vietnamnet.vn/en/hcmc-faces-tremendous-pressure-on-parking-spaces-2077838.html) Spontaneous parking lots have lost the aesthetics of the urban area without meeting safety and convenience. So, we believe that the development of smart parking lot is an urgent need for our current situation. Demand for parking lot in Vietnam Realizing the reality of many shortcomings in car parking in Ho Chi Minh City.
Our team has launched a smart parking lot system. Thus, the product is highly appreciated for safety for users while saving time and employee costs. According to the statistics of Ho Chi Minh City Police, the average in the city occurred 50-100% of motorbike losses in which the hospitals, supermarkets, commercial centers, markets, etc. The main reason is because the crook used a fake ticket, the number plate or the car holder lost the ticket.
The idea of the parking system was born from there. With high security, our team decided to apply this model as the topic for our project. We will provide the actual data to persuade investors, potential partners or readers as your business will attract many customers in a growing business and can guarantee sales out defy competition. This is one of the most important parts of the business plan, including considering the size of the current market and market development trends.
Many the next part of the business plan as the production part, marketing, and the total capital you 3 need, will be based on the forecast about sales mentioned in this section. Here are the parts that we want to mention in product market analysis. Cars parked on a street affect other traffic (Source: https://e.net/news/news/vietnamese-cities-suffer-from-lack-of-parking-spaces-4552003.html) As we have seen, the needs of the customer are endless but the ability to respond is finite, so it is necessary to focus on the current urgent needs of our customers. Therefore, our team has focused on finding out and saving the needs of customers about products that we want to introduce to customers, a project that feasibility is quite high, meeting the need for the current urgent level.
