Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

Incremental improvement is the most common, near-term approach to upgrading railway corridors to achieve high speeds. However, investing in incremental improvement is expensive, efficient utilization of the investing is one of the objectives. Existing infrastructure or rolling stock can be improved in various ways to allow for increasing speeds and reducing travel time along a route. Each track section has a characteristic set of opportunities for increasing speed and their corresponding effect on travel time reduction, along with an associated set of costs. Similarly, each type of rolling stock has the potential to increase operational speed and reduce travel time, corresponding to a specific price tag. And investing in both existing infrastructure and rolling stock should consider the Life-cycle cost  （LCC）.
This research focuses on the development of a decision support process, Railway Route Improvement Optimizer (RRIO), using mathematical programming to identify the most cost-effective strategy for reducing corridor travel time given a prescribed performance goal and budget.  Based on information of the current network and traffic, and the available investment options, numerical results show that RRIO can successfully determine the optimal solution to which sections should be upgraded, the type of rolling stock that should be implemented, and the fleet size.  To improve the solution efficiency, we also developed a solution algorithm to improve the solution efficiency by nearly 85% and maintain the solution quality within 3% optimality gap.  With this tool, railway agencies can maximize return from capital investment and maintain reliable services at the same time.
