# GIS-Based Multi-Objective Routing Approach for Street-Based Sporting-Event Routing
## 1 Introduction
### Literature Review  
#### 1.2.1 Limitations of the Street-Based Event-Planning Process  
The planning of a typical street-based sporting event is under the auspices of competent government and event organizers. Governments lack expertise in sports, and event planners focus on the success of events [5]. The difference between these two perspectives creates a significant amount of time in decision making because of the differences in requirements. Moreover, when an event planner lacks urban and social information about a venue, it causes problems in devising an event route that is unsuitable for the conditions of the host city [1]. In addition, since street-based sporting events require the occupation of public roads for a relatively short period of time, the negative impact is sometimes not considered in the success of the event, even if citizens are inconvenienced.  
Route searches for existing street-based sports events are subjective and inefficiently planned through media, such as web maps. First, a route suitable for the physical conditions

of the track required for a sports event was searched through a web map. Subsequently, surveys on the current status of the route explored through on-site inspections and the investigation of obstructions were conducted. Field visits are time-consuming. In fact, four weeks were spent on field research at the 2022 Jamsil E-PRIX. In addition, if factors that make it impossible to hold an event are identified during site surveys, the route is searched again. Such manual route searches in the planning stage are inefficient and lack objective evaluations of the selected route, and searches for various alternatives are impossible. Street-based sporting events, such as bicycle races and marathons, as well as the Formula E World Championship, are very diverse and frequent all over the world. In other words, it is necessary to propose a digital-based objective decision-making process to solve inefficient processes during the planning stages of numerous street-based sports events.  
The route searches for current distance-based sports event can be performed more quickly and efficiently using the GIS-based routing methodology suggested in various previous studies. The GIS environment provided by the government includes information regarding the infrastructure of a city. This can be used to efficiently conduct obstruction investigations in a digital environment during the early stages of planning. Moreover, it is possible to search for a route that considers the city infrastructure in the initial route search. In addition, through the integration of GIS and BIM environments, a city model can be visualized, and an evaluation model can be created [7], which can be used as a decision-making model suitable for street-based sports events. Therefore, in this study, we propose a comprehensive decision-making framework based on GIS-routing-BIM, which can be used to solve the problems of current street-based sports events; to this end, we selected a specific city, conducted an experiment, and discuss the results in this paper.
