【正文】 funds input, A 卷 第 21 頁 / 共 106 頁 stake setting. According to statistics, last year the city has erected building control zone peg 820, construction control area boundary markers 815 . the second is highway greening and beautification work enhance the road area remediation effectiveness. Will highway greening and beautification work as road area remediation of a key, invite garden experts to guide the design of green, the implementation of high standards for ecological landscape highway activities to create, five years, I board greening mileage of more than 900 kilometers, appropriate road greening greening rate of 100%, effectively enhance the city road greening level and grade, adds a sharp scenery line for **********. Third, rectification of illegal construction and occupation of the road has been checked. By through the town, crossing the road on many occasions to carry out concentrated rectification actions, to clear the remnants of the wall, broken Archives of highways in strict accordance with the wall of building structures and the illegal deposits, remediation along the Jeeves, Jeeves placed advertisements and vehicle maintenance, car washing and other acts, standardize and purification on both sides of the highway billboards and other non road signs, I city of national and provincial highway basic elimination of the dirty, chaotic, poor, blocking A 卷 第 22 頁 / 共 106 頁 phenomenon, highway traffic environment purification, landscaping. (2) to strengthen the management on the basic data management. The level of the archives management regulations, formulate the file management system , the establishment of the road, the implementation of the file manager, file collection, filing, sorting, filing, confidentiality, custody, borrow, identification pin Destroy the standardization. 2, standardized management, enhance service image (a) evaluation system to further improve in order to strengthen and standardize guidance and assessment of each county (area) bureau of highways management work, the Bureau developed a *** City Highway Bureau highways management assessment implementation measures (Trial). To regularly check for half a year, yearend assessment and irregular random sampling bined, taking the spot road inspections, sampling sections, listening to the reports, archives data check, for each county (area) bureau of highways management work implementation of the special assessment. According to the annual prehensive assessment appraisal score results, evaluation of outstanding, excellent pliance and Not up to the standard of four grades. And in accordance with the level of assessment, the award on behalf of dial highway management funds. Total score is above A 卷 第 23 頁 / 共 106 頁 95%, is excellent, 10 million yuan reward。 total score of 90 94 for excellent, 8 million yuan reward。 for the total score of 80 89 points for standard, reward 50000 yuan. On the total score is less than 79 points for nonpliance unit, circulate a notice of criticism. (II) Sheung inspection work to further standardize a is in place to ensure the inspection. National and provincial trunk highway patrol monthly not less than 20 days, State Road a week of not less than 3 times, dart a week of not less than 2 times. The second is to explore and promote the electronic patrol monitoring. City highway patrol vehicles are installed on the highway patrol vehicle monitoring system。 highway law enforcement personnel are equipped with a recorder for law enforcement, on the process of supervision and law enforcement to ensure evidence has played an effective role.

The fourth is the establishment of highway maintenance and inspections mechanism. The city39。s 19 country and provincial trunk highway maintenance center equipped with the CPPCC keeper, and to develop a road of the Chinese people39。s Political Consultative Conference tube member A 卷 第 24 頁 / 共 106 頁 responsibilities. According to statistics, in 2020 (on the road. Day.... Stop the road mileage, 17 cases。 clean up debris on both sides of the road 20 , demolition billboard 30, demolition chaotic scaffolding house 3, clean Lane Hawking 15.) (3) road permit work to further strengthen the implementation of administrative licensing system, strengthen the supervision and administration of the licensing. Strict implementation of the Guangdong Province highways license implementation measures . According to the provisions of the road approval procedures and processes to carry out road license, do according to the law, the license in accordance with the law, shall be subject to examination and approval of the. Implement the collective examination and approval, to strengthen supervision. Highways and approval of business implementation of technical review of administrative approval and separation, the audit focused on the more plex involved in the road licensing matters, collective decisionmaking, to improve the scientific nature of the road administrative examination and approval, reduce approval corruption risks. Second is to promote the In administrative permission of information technology to improve service quality.
