Two breakwaters and some high-piled wharfs are planning in Dongjiakou Port area of Qingdao Port. Taking the case as an example, the paper established the hydrodynamic model and water environment model to research the impact of breakwaters and wharfs planning and construction on marine dynamics and environment. Simulation results demonstrate that the currents velocity are no longer changing from a distance of 2 kilometers away. The tidal volume is decreasing about 0.07% after the planning implementation. The suspended sediment caused by port construction has an adverse impact on water quality of surrounding waters. The conclusion can benefit for port planning and construction.","PeriodicalId":212840,"journal":{"name":"Conference on Smart Transportation and City Engineering","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124568478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, Rizhao Port has also strengthened the development of water-rail intermodal transport, and only by accurately judging and evaluating the current status of water-rail intermodal transport in Rizhao Port can enlighten and point out the direction for future development. This paper selects four secondary indicators of organization coordination, capability coordination, information coordination and government policy, uses the Topsis model to evaluate the coordination of the water-rail intermodal transportation system in Rizhao Port, and obtains the coordination of the water-rail intermodal transportation system in Rizhao Port is good, but the allocation of equipment resources in the port is still unreasonable, and all the production capacity of the corresponding equipment in the port is not fully utilized. At the same time, although the information coordination of the port is very good, it can still be further integrated with the information data of the railway system to form a more complete information platform, which will be more conducive to cooperation and communication between the two transportation systems.","PeriodicalId":212840,"journal":{"name":"Conference on Smart Transportation and City Engineering","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121057282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to the Spyro extremum principle, the lamp panel array is analyzed and designed, and the red, green and blue (RGB) three-color light mixing is analyzed according to the Glassman color mixing law and the light mixing principle of the International Commission on Illumination (CIE) standard chromaticity system. The feasibility of modulation is established; the functional relationship between duty cycle, chromaticity coordinates and correlated color temperature is established respectively, and the modulation simulation and experiment of three RGB channels are carried out by means of pulse width modulation. It can be seen from the verification results that controlling the RGB three-color LED lamp beads according to the duty cycle can accurately set the relevant chromaticity coordinates of each color light, and realize the chromaticity in different situations. The light panel is expected to solve the problem of signal color decay and chromaticity coordinate shift in special weather conditions.","PeriodicalId":212840,"journal":{"name":"Conference on Smart Transportation and City Engineering","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126004924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to promote the low-carbon process of the transportation industry, based on the differentiated charging of expressways, this paper constructs a carbon emission calculation model and a carbon pricing model from the perspective of carbon emission reduction income, and analyzes the carbon emissions under different charging rates of expressways and the economic benefits of carbon emission reduction. On this basis, the comprehensive income of the high-speed group is composed of two parts: toll income and economic by carbon emission reduction. Considering the benefits of carbon emission reduction, the formulation of highway toll rates can bring more environmental benefits under the condition of ensuring the actual economic benefits of the high-speed group. The results show that when the toll rate is 2.0 yuan/km, the high-speed group can obtain the optimal carbon emission reduction benefits and toll benefits. This study can promote the low-carbon process of the transportation industry and provide a reference for the amount and method of government subsidies to the transportation sector.","PeriodicalId":212840,"journal":{"name":"Conference on Smart Transportation and City Engineering","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116839401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
