The problems of LED display appliciations in the transportation5/29/2012
The application of LED display systems for improving the traffic order and traffic information services are play a crucial role. In China's urbanization process, the application of intelligent transportation systems brought new opportunities to LED display industry for transport applications. Due to the biased understanding on the traffic guidance systems and outdoor LED display products, traffic LED display still have many problems in the application on the market!
1. LED display hardware and software development is uneven, which focus on economies of scale rather than pragmatic. The intelligent of LED traffic guidance system is related to its hardware and software technologies development, and now it has large investment on hardware and inadequate investment in the comprehensive analysis of traffic dynamics model, algorithm and system control software, which make the traffic guidance information is mainly qualitative fuzzy information and lack of quantitative information. The traffic guidance system hovering in the low-level and has large gap of the intelligent requirements.
2. Selection and design of traffic LED screen products did not proceed from the actual needs and blind pursuit of the new. In practical applications, the traffic guidance system release of information for drivers, which need simple, clear and eye-catching. It should avoid the use of complex multi-gray-scale graphics and animated content, otherwise it will affect the viewing experience, and even lead to traffic accidents. At present, due to have not deep enough understanding of transport system, it lack of careful study on the specific needs of traffic-induced. So on the design and selection of traffic LED display, it blind pursuit of full-color LED display, high gray scale animation and other insignificant features.
3. The LED display design orientation is divorced from reality, ignoring the economic rationality. In the choice of LED display products, one-sided pursuit of product selection, brand, brightness and other factors, to the neglect of the structural design and take the appropriate measures to ensure the optical performance and quality stability of the LED material; did not consider the cost and maintenance costs increase.
