1, the layout has changed, such as Beixin Road, which used to be mixed with people and cars, but now it is motor vehicles, buses, sidewalks and blind roads, arranged in turn.
2. The width has changed, such as Friendship Road, which used to be a two-way four-lane road, but now it is a two-way six-lane road.
3. Higher security and humanization. There is an isolation belt and a safe passage in the middle, which was not used before.
4. Set up electronic police at major traffic intersections (78 in the city) to warn drivers to abide by laws and regulations at all times.
5, more humane, manifested in the addition of blind roads, road signs, slogans and so on. (such as a drop of wine from the driver, two tears from relatives, etc. )
6, more and more clean!
7. This is more convenient. Ring highway network (O+X type) has been built, and the convenient transportation conditions are equivalent to those of an international metropolis.
Changes in the environment
1. 1 atmospheric environment
1. 1. 1 status
In 2005, the city's atmospheric environmental quality showed an improvement trend. The main components of air pollutants are particulate matter, sulfur dioxide and nitrogen dioxide, in which sulfur dioxide and particulate matter account for a large proportion. Pollutants mainly come from waste gas from coal-fired facilities, automobile exhaust and secondary dust from urban roads and construction sites. The air environmental quality in the central city is still Grade III. In 2005, the main pollutants in the ambient air of counties and urban areas were total suspended particles, of which Luanxian and Laoting reached the second-class national standard of ambient air quality, while Luannan, New District, Tang Haixian, Fengrun, Qian 'an, yutian county, Qianxi and zunhua city reached the third-class standard. See figure 1- 1.
1. 1.2 Emission status of air pollutants
In 2005, the emission compliance rates of soot, industrial dust and sulfur dioxide in the whole city were 98.63%, 97.98% and 98.24% respectively, all higher than the previous year. The emissions of soot, industrial dust and sulfur dioxide in the city are 1.837 million tons, 236,500 tons and 3 1.65438 respectively.
1.2 water environment
1.2. 1 status
Among more than 80 rivers in this city, Douhe, Luanhe, Lihe, He Lin, Huxiang and Shahe are the six major rivers. In 2005, six major rivers were routinely monitored 12 times, with 13 monitoring sections and more than 30 monitoring items. The results show that the water quality of the reservoir section in the upper reaches of the river is generally good, reaching Class II water quality, while the water quality of the river section below the reservoir dam site is generally poor due to the pollution of domestic sewage and industrial wastewater flowing through towns.
In 2005, the county-level monitoring stations in our city monitored 16 rivers, of which Class II water quality accounted for 16.7%, Class III water quality accounted for 20.8%, Class IV water quality accounted for 6.2%, Class V water quality accounted for 14.6%, and inferior to Class V water quality accounted for 37.5%.

1.3.3 main control measures
The city vigorously carried out community garbage bagging treatment, strengthened and standardized garbage removal management, effectively avoided garbage accumulation and random floating, and ensured Nissan Nissin; Closed garbage transfer stations will be established in all concentrated communities in the city, sealed garbage transport vehicles will be purchased, sealed collection and transportation will be implemented, and all domestic garbage will enter the garbage disposal site for safe landfill. Strengthen the supervision of medical waste, and all medical waste in the urban area will be transported to the cleaning medical waste treatment company for harmless treatment.

1.4.2 atmospheric environment
Tangshan has built an automatic monitoring system for ambient air quality 65438-0986. At present, there are supply and marketing cooperatives (commercial areas), radar stations (clean areas) and materials bureaus (traffic areas) in operation. The main monitoring items of ambient air quality are inhalable particulate matter, sulfur dioxide and nitrogen dioxide. See figure 1-5.
General situation of urban air quality
In 2005, the average annual concentration of inhalable particulate matter in ambient air in Tangshan was 0.095mg/Nm3, which was 0.0 17 mg/nm3 lower than the previous year. The average annual concentration of sulfur dioxide is 0.085 mg/Nm3, which is basically the same as that of the previous year, but still exceeds the national secondary standard by 0.42 times. The annual average value of nitrogen dioxide is 0.043 mg/Nm3, which is basically the same as the previous year and reaches the national second-class standard. (see table 1-4)
