According to the official website of the Ministry of Communications, the Ministry of Communications recently issued the "13th Five-Year Plan for Urban Public Transport" (the "Outline"). The "Outline" proposes that it is necessary to study and promote the urban traffic congestion charging policy in a timely manner according to the urban traffic conditions; Adopt the "two limits" policy of motor vehicle purchase restriction and restriction, and avoid the normalization of the "two limits" policy. The cities that have already been implemented shall, in due course, study and establish necessary supporting policies or alternative measures.
Avoid the restrictions on the purchase of cars, the normalization of congestion charges research and advance on June 14, Wangjing Bridge, the evening peaks in both directions.

Focus 1 Cities should be cautious in adopting motor vehicle restrictions and purchases, and the “Outline” proposes measures to alleviate urban traffic congestion. It is worth noting that the “Outline” formulates various urban public transport development indicators during the “13th Five-Year Plan” period based on the urban population size. In cities with a population of more than 5 million, the proportion of green travel will be around 75%. The city bus station has a coverage rate of 100% at 500 meters, which means that citizens can find bus stops within 500 meters.
Alleviate urban traffic congestion, and guide all localities to establish differentiated traffic congestion control measures based on economic means and administrative means. According to the urban traffic conditions, timely study and promote the urban traffic congestion charging policy. Carefully adopt the "two limits" policy for motor vehicle purchase restriction and restriction, and avoid the normalization of the "two limits" policy; cities that have already implemented, timely study and establish necessary supporting policies or alternative measures.
Beijing, Shanghai, Guangzhou, Chengdu and other places have implemented policies such as restrictions and purchase restrictions, and some large cities have even adopted a two-limit policy. According to the "Outline", the above cities should study supporting policies or alternative measures in due course.
Focus 2 Standard development network to reserve taxis The reporter found that in the "Outline", it is necessary to strengthen taxi operation and dispatch management, make full use of mobile internet technology, and effectively reduce the taxi flight rate. This content requirement has been mentioned in the last year. On the one hand, it guides the parade taxis to provide operational services through telecommunications and the Internet, encourages the parade to expand the service functions, and uses the Internet and other technologies to realize the transformation and upgrading of the industry. service. On the other hand, the normative development network subscribes to taxis and implements license management for network booking taxi operators, vehicles and drivers. At present, it has been more than a year since the "Guidance Opinions" collected opinions to solicit opinions from the society, and it has not yet been introduced.
According to the traffic development plan of the 13th Five-Year Plan period in Beijing, the P+R parking lot that facilitates the public to transfer to the bus outside the central city will continue to increase. According to the person in charge of the relevant department of the Transportation Committee, the future P+R parking lot will be bound to the new The open track lines will be built synchronously, and the old lines will gradually improve such parking facilities, increase the proportion of parking and transfer, and reduce the amount of car trips in the central city.
Focus 3 The central city will realize the bus 500 meters on the “13th Five-Year Plan” period, and comprehensively promote the construction of “bus city” in cities above the city level. After 5 years of construction, the city will be able to get on the train in 500 meters. The proportion of green transportation in urban transportation will reach 75% or more. In cities with a population of 5 million or more, the on-time rate of public transportation should reach more than 75%. In the process of “bus city” construction, it will also actively promote the promotion and application of buses in new energy cities, promote the development of “Internet + city bus”, and innovate and develop various new service modes.
The reporter learned from the Beijing Municipal Transportation Department that Beijing strives to reach more than 90% of the passengers in the central city by the end of 2017. The distance from the nearest bus stop is no more than 500 meters. The average walking distance within the five rings can reach the rail transit station. During the five-phase period, this work will continue to advance. According to the person in charge of the bus department, a new generation of bus intelligent dispatching system is currently being researched. This system will start the vehicle according to the daily operation of the line, road condition information and vehicle allocation, and reduce the waiting time of the citizens.

PE Plastic Sheet

PE plastic Sheet, full name is Polyethylene Sheet.

Physical properties: PE plastic Sheet is the most simple structure of the macromolecular organic compounds, the world's most widely used polymer materials, composed of ethylene polymerization, depending on the density is divided into high density polyethylene, medium density polyethylene and low density polyethylene.


Classification of PE Sheet
(1) LDPE Sheet
Low density polyethylene Sheet (also known as high pressure polyethylene Sheet)

(2) LLDPE Sheet
Linear low density polyethylene

(3) MDPE Sheet
Medium density polyethylene

(4) HDPE Sheet
High density polyethylene (also known as low pressure polyethylene)


(5) UHMWPE Sheet

Ultra high molecular weight polyethylene

(6)Modified polyethylene sheet
Chlorinated polyethylene (CPE) and crosslinked polyethylene (PEX)

(7)Ethylene - ethylene copolymer
Ethylene/propylene copolymer (plastic), EVA, ethylene, ethylene butene copolymer - other olefins, such as octene POE, cyclic olefin copolymer, ethylene/unsaturated ester copolymer (EAA, EMAA, EEA, EMA, EMMA, EMAH).
Polyethylene, which has a molecular weight of 3 million to 6 million, is known as UHMWPE.

Ultra high molecular weight polyethylene is very strong and can be used for body armor.


Applications:
1. Papermaking industry: suction box board, scraper, molding plate, bearing, gear;
2. Mining industry: charging barrel, abrasive and adhesive-resistant back lining for warehouses;
3. Chemical industry: acid pump, filter plate, worm gear, bearing;
4. Food industry: packing machinery parts, bottle guide, screw, wear plate, slide way, stud weld, roller and other transmission parts;
5. Textile industry:buffer board;
6. Food processing industry: chopping block, refrigerating plant;

7. Wharf: anti-collision board.


Advantages:
1. Acid and alkali resistance, resistance to organic solvents
2. Excellent electrical insulation and static resistance
3, Can still maintain a certain touness even at low temperature
4. Extremely high impact strength
5. Low friction coefficient
6. Non-toxic
7. Low water absorption
8.Lower density than any other thermoplastic plastics (<1g/cm3)

Disadvantages:
PE Plastic sheet have Weak mechanical property, air permeability, easy deformation, easy ageing, brittle, brittle less than PP, easy stress cracking, surface hardness, easy to scratch.
Difficult to print, in printing, surface discharge treatment, cannot electroplating, the surface has no luster.
