4. Microwave traffic flow detector

（1） Brief Introduction
 Microwave traffic flow detecting system is designed to detect the essential information on outward run flow, occupancy, average velocity and vehicle type, etc；
 The microwave traffic flow detector developed by Beijing Zhongjiaoguotong ITS Technology Co., Ltd came into the market in 2004, breaking up the monopoly of domestic microwave traffic flow detector market by the products of the two original overseas companies.
 Since the product was launched on the market, market competition has emerged. As a result, the selling price per unit has been lowered to about RMB 25,000 Yuan in 2007 year after year from the long-lasting RMB 50,000 to 60,000 Yuan before 2005.
 The share of our products in the domestic market share is increasingly rising, with 82 to 89 units of the Center accounting for 27%-28% of the whole expressway market which boasted 300 - 350 units in 2005 and with 95 to 100 units of the Center accounting for 31% - 33% of the whole expressway market which boasted 300 - 320 units in 2006 respectively.
 Our products have been successively put into application in Jiangsu, Guangdong, Anhui, Henan, Fujian, Beijing, Yunnan, Shanxi, Tianjin, etc.
