For beginners, submitting a paper for the first time is a very nervous thing. Before submitting your paper, make sure that you have read the magazine guides and understood their formats and requirements. Before writing an article, we suggest that you check the previous articles published by this journal to understand the review process and other requirements of this journal.

Next, you need to select a DOI (Digital Object Identifier) registry to create a DOI for your paper. DOI is a unique identifier that can be used to identify and quote your paper. You can select multiple registration agencies, but you only need to select one to create a DOI. Choose a reliable registration agency to ensure that your DOI is always valid.

Make sure that your paper has been peer-reviewed before creating DOI. This is an important step, because peer review can ensure that your paper meets academic standards and journal requirements. If your paper is rejected, please read the feedback from the reviewers carefully and make necessary amendments and improvements to your paper.

When creating DOI, you need to provide some metadata, such as title, author, journal name and publication date. Make sure you provide accurate metadata so that readers can easily find and quote your paper. Once the DOI is successfully created, you can add it to your paper and include it in the citation.

Make sure that you have carefully checked and revised your paper before submitting it. Check grammar, spelling and format errors to ensure that your paper meets the format and requirements of the journal. Finally, submit your paper and be ready to share your research results with colleagues and other scholars.

Doi means the diversion of people and vehicles; On the road, people and cars are completely separated, and each goes his own way without interference. Include footbridges, underpasses, pedestrian streets and pedestrian precincts.

The separation of people and vehicles completely separates people and vehicles without interfering with each other, which plays an important role in relieving urban traffic pressure. At the same time, it has truly achieved the goal from "people-oriented" to both people and vehicles.
