Description

Technical Field [0001] The present invention relates to a method for expressing a service level of road capacity analysis,

The present invention relates to a service level expression method of road capacity analysis, and more particularly, to a service level representation method of road capacity analysis. More particularly, the present invention relates to a method of expressing a service level of a vehicle passing through an intersection and a road, To a service level representation method of road capacity analysis.

At the time of the city's growth, government-led large-scale construction projects were dominant as measures to solve transportation problems. Recently, as the population abruptly stopped, the redevelopment and reconstruction projects to improve the existing residential environment and improve the quality of the city are actively pursued rather than the external growth, and the private role and efforts for solving traffic problems are urgently required.

Currently, according to the principle of beneficiary burden, the traffic impact assessment system is legislated to induce private companies to voluntarily solve traffic problems caused by development projects.

The traffic impact assessment is the analysis and evaluation of the impacts on the transportation system of the development area or the surrounding area of the development site in advance when implementing a business that causes or may cause a large amount of traffic demand, .

The purpose of the traffic impact assessment is to examine the appropriateness of the size and nature of the project in light of the current status of land use and traffic system in the area, And to consider them in the planning process. Third, if the implementation of the project has a ripple effect on the traffic system in the surrounding area, or if the necessity of public investment is required by this, it is necessary to identify the cause and the beneficiary It is to determine the principle of cost burden.

However, at present, there is a lack of support system to make accurate decision making by the traffic impact assessment review committee members.

Therefore, even if the traffic impact assessment is carried out before the development project, serious traffic problems are caused on the surrounding roads after the completion of the project and it becomes a social problem. In order to solve this problem, there are cases in which citizens need to prepare additional measures.

Therefore, in order to improve the effectiveness of traffic impact assessment, it is necessary to accurately diagnose traffic problems caused by development projects and effectively provide service levels for road traffic facilities so that review committee members can understand them.

FIG. 1 is a view for explaining a grade of a service level at an intersection and a street provided by the road capacity manual, and FIG. 2 is a view for explaining a method of expressing the service level of FIG.

Referring to FIG. 1, average lag information at intersections and roads and service level as a result of road capacity analysis are the most frequently used information for traffic management services such as traffic impact evaluation, which is performed to solve urban traffic problems. Service levels for these intersections and entrances can be identified in the breakdown tables provided by the Road Capacity Manual (2013, Ministry of Land, Transport and Maritime Affairs) according to signal intersection analysis.

Meanwhile, as shown in FIG. 2, in order to express the traffic lag in the horizontal direction, the horizontal lag display method is used in which the horizontal line is divided into the vehicle traveling direction and displayed as a color lamp.

This transverse lag expression method has a problem that lag information can not be expressed for the entire intersection and it is difficult to visually identify the lag when the width of the road is not wide. In addition, although the traffic jam occurring after the vehicle arrives at the intersection mostly occurs in the transverse direction of the city center, the conventional transverse lag display method displays only the lag information for the entire transverse direction, There is a problem in that it does not fit the actual traffic situation.

However, the analyzing apparatus 100 may be implemented as a large-capacity data storing means, Can be implemented.

FIG. 4 is a flowchart for explaining a method of expressing a service level of road capacity analysis according to an embodiment of the present invention, and FIG. 5 is a view for explaining a map of a transportation planning route according to FIG.

4 and 5, the traffic impact assessment decision support system collects information on the development sites when the development projects such as building construction, land development, and road construction are performed (S1). At this time, The information may be at least one or more of the following information: the area of the area, the floor area, the number of buildings, the number of households, the length and width of the road, the type of road lane (eg, two lanes, four lanes, six lanes) .

The analysis apparatus 100 calculates an average value of the vehicle passing through a traffic facility including an intersection and a road within a predetermined radius based on a development site and calculates a service level based on the road capacity analysis for the traffic facility. S2)

The service level of the traffic facility is an index that describes the status of the traffic facility and is expressed as A, B, C, D, E, F, FF, FFF. The criterion that distinguishes service levels from intersections and roads is that the distance between the intersection and the street (the value for ideal roads and traffic conditions) when the vehicle is operated at a limited speed with no traffic at all The average lag value of the vehicle, which represents the time spent, is used.

The analysis apparatus 100 displays intersection names and cross names of the respective intersections in the form of symbols in the intersection and the cross section on the street grid map including the development site. Expresses the service level of the intersection as a whole and the service level of the street as a color lamp according to the level of the service level calculated and expresses the average lag value of the vehicle at each intersection and the street as a numerical value to complete the transportation plan street grid map. (S4 to S6)

5, the analysis apparatus 100 expresses an intersection as a first symbol 510 and a transverse direction as a second symbol 520 on a street network map, and the first symbol 510 And the second symbol 520 may be formed as a polygon having a tip portion.

The analysis apparatus 100 displays a service level rating for the intersection in the first symbol 510 and a color lamp of a color corresponding to the service level rating, The numerical value of the intersection name (for example, Middle East intersection, intersection intersection, etc.) and the average lag value of the intersection (for example, 94.0, 99.6, etc.)

In addition, the analysis apparatus 100 displays the grade of the service level and the average lag value (for example, E (95.3), D (66.1), etc.) in the second symbol 520 on the road network map And is expressed by a color lamp of a color corresponding to the grade of the service level and expresses a name of a street (for example, a house, a fresh water, a waterway, etc.) on one side of the second symbol 520.

At this time, the second symbol 520 is a polygon formed with leading ends 521 and 522 to indicate an approach direction of an intersection, and the leading ends 521 and 522 are connected to the first symbol 510. That is, the first peak 521 of the second symbol 520 indicates the approach direction to the middle east intersection and the second peak 522 indicates the approach direction to the intersection.

As shown in FIG. 5, the service level of the horizontal direction upstream and the descending line, that is, the approach direction of both sides of the crossing intersection, is F (124.5) and FF (238.0).

The second symbol 520 determines the length and width of the polygon by applying the length and width of the polygon, and bisects the polygon to apply the inlet of the polygon. In addition to the pentagon, the second symbol 520 may be a block shape, arrow shape, or similar shape.

Therefore, the analysis apparatus 100 uses the map of the transportation plan road network as an evaluation index when performing the traffic impact assessment to compare the changes in the service level of the transportation facilities before and after the development project for the development site (S7).

FIG. 6 is a view for explaining an example of a traffic plan road network map applied as an evaluation index of a traffic impact evaluation according to an embodiment of the present invention, and FIG. FIG. 8 is a view for explaining an example of a transportation plan cross-country map represented in the airline phase according to an embodiment of the present invention.

6 to 8, it is important for the analysis apparatus 100 to compare and analyze changes in the service level of the transportation facilities before and after the development project for the development site. In order to establish appropriate transportation measures for the development project, It is necessary to simultaneously grasp the analysis results of the entire intersection and the width of the surrounding area.

Accordingly, the analysis apparatus 100 can effectively grasp the results of traffic analysis around the development site through the traffic plan road map when the traffic impact assessment is performed. That is, as shown in FIG. 6, the traffic plan road network map simultaneously expresses the service levels of the road and the intersection, so that the shape of the symbol on the map, the color of the symbol, and the numerical value are displayed. The results of the analysis can be confirmed.

Such a traffic plan cross-section map can be applied not only to a two-dimensional space map but also to a three-dimensional space map or an aerial photograph, as shown in Figs. 6 and 7, and also includes first and second symbols representing an intersection and a cross Dimensional symbol or a three-dimensional symbol.
