Analysis Of The Performance East Circle Road Of Sidoarjo

Along with the increasing number of the population of Sidoarjo, this has an i mpact on traffic volume, it occurs on the road of Gedangan roads to Buduran, therefore carried out the transfer of road access to the East Ring Road with specialized for heavy vehicles, due to the transfer of the road, it is necessary to perform the analysis of the East circumference road performance. The research aims to determine the magnitude of the influence of heavy vehicle volumes on the road performance of the East Ring road. The performance Of the east circumference traffic by counting the Level Of Service (LOS) and calculating the volume Of the vehicle compared to the road capacity (degree Of saturation). Traffic volume Data surveyed for 2 days (6 and 10 August 2020), for 6 hours per day at 06.00 – 08.00, 12.00 – 14.00, and 16.00 – 18.00. The analysis of road performance is using the Manual road Capacity (MKJI) method with a degree of saturation (DS) as the main indicator of road performance. The results of the analysis showed the performance of the road on the condition of the excitation point 1 the value of saturation of 0.61 and in point 2 of the value of saturation 0.97 and the result of service level of roadway 1 is C (steady current speed and motion-controlled vehicles) and in point 2 is E (current unstable speed sometimes stalled close request of capacity).


Introduction
East Circle Sidoarjo is vital to access that is part of the whole ring road that circles the city of Sidoarjo and serves as an alternative way within the city. The road also plays a role to divert and facilitate the flow of traffic that crosses the cit y of Sidoarjo. The development that occurs in the city of Sidoarjo must certainly be in a good traffic management system and support infrastructure [1]. East Ring Road Sidoarjo According to its function is classified as a primary arterial road, i.e. the road that serves the main transport with the characteristics of a long-distance journey of high average speed and the number of entrances is limited as efficiently as possible, with the role of distribution service services for urban communities. The criteria on the primary arterial road are that the road is designed based on the lowest plan speed of 60 kilometers per hour based on the government regulation RI number 34 the year 2006. Minimum road width 11 meters [2]. This research aims to know the magnitude of the influence of heavy vehicle volume to the performance of the East Ring Road (East Drive), for the city of Sidoarjo certainly very much expect the city of Sidoarjo to be growing but still comfortable to be in the community in the city of Sidoarjo. Therefore, the city of Sidoarjo should still prioritize the smooth transportation that can certainly be done by implementing the transportation system and the appropriate traffic settings. [3]. The research was conducted on the East Ring road by collecting primary data and secondary data, primary data include road geometric data, side barriers, and traffic volume, while the secondary data include research location data and the population of Sidoarjo Regency according to the Indonesian population census in 2018, to solve this problem, planned traffic management is required so that the solution at one point will not cause problems at other points. To plan this traffic management, it is important to know the behavior of traffic characteristics such as volume, speed, and density. By knowing the volume and speed of a road segment, it can be obtained the performance value of the road. [2].

Geometric Conditions
Geometric roads are one of the main characteristics of the road that will affect the capacity and performance of roads if burdened traffic. In Indonesia Road capacity Manual (MKJI) 1997 [5], among which is included in the geometry of the road as follows : 1. Road type: Different types of roads will show different performance on certain traffic loading, for example, divided and undivided roads, one-way roads. Types of urban roads listed in Manual Road capacity Indonesia MKJI 1997 are as follows : a. A two-way two-lane path without median (2/2 UD) b. Two-way four-lane path 1) Undivided (without median) (4/2 UD) 2) Divided (with median) (4/2 D) c. Two-way Split-Lane Street (6/2 D) d. One-Way road (1-3/1) 2. Traffic path width: Free current speed and capacity increases with a wide increase in the traffic path. According to Sukirman's View (1994), The traffic lane is the entire road section that is reserved for vehicular traffic. The width of the traffic path is the most defining part of the road crossing width. 3. Shoulder/Curb: As the boundary between traffic paths and sidewalks is very influential on the impact of roadside barriers on capacity and speed. The road capacity with the Curb is smaller than the shoulder road. Further capacity decreases if there is a fixed barrier near the edge of the traffic path, depending on whether the road has a curb or shoulder. 4. Presence or absence of a median, well-planned median increases capacity

Side Barriers
Side barriers, namely roadside activities that can cause conflict and affect the movement of traffic flow and reduce the function of road performance. Pedestrians crossing or walking cause traffic to pause to wait for passing vehicles while pedestrians cross. There is lost time due to stop and wait, causing a reduced road capacity due to increased travel time for a road section. With the market activities around the road, the activity on the road is increasingly higher. In MKJI 1997. The high level of side barriers also caused many traders who used sidewalks to sell and the existing condition of sidewalks that could not be passed by pedestrians, so that pedestrians prefer to walk on the road shoulder. (Conny Maretia P. Putri, Symposium X FSTPT, 2007) The side barrier level is grouped into five classes as a function of the incidence of side barriers along with the observed road segments. Almost cities/markets, trade activities Very High VH Source : [5] Side barriers are particularly influential for the capacity and performance of the road, while the criteria for side barriers are divided into 4 weights: a. Pedestrians (weight = 0.5) b. Public transport and other vehicles stop (weight = 1.0) c. Slow vehicles (e.g. Becak, horse carriage) (weight = 0.4) d. ehicle out of the land next to the road (weight = 0.7)

Flow and traffic composition
Based on MKJI 1997 the main function of a road is to provide transportation services so that road wearers can safely and comfortably drive. The parameters of traffic flows that are an important factor in traffic planning are volume, speed, and traffic density. [5]

Level Of Servis
Level of Service" is the level of service of a road that describes the quality of a road and is the limit of operating conditions. The level of service of the road indicates the quality of the road measured by several factors, namely speed and time of travel, density, delay, traffic flow and saturation current, and degree of saturation [5].

Speed Observation Method
Vehicle speed can be observed and calculated by moving observer methods. One of the methods developed on how this moving observer is the Moving Car Observer method. This method is done by collecting data that includes travel time as well as traffic flow both in the direction as well as in opposite directions with observer vehicles. With this method, you will get the average speed of the vehicle on a track when the moving vehicle is obtained by dividing the length of the path divided by the time the vehicle moves through the line. [5]

Method
The research was classified in descriptive research, this study was conducted to give a more detailed picture of a symptom or phenomenon. As a first step is the collection of data needed to support research to get the correct data, this type of data is divided into 2 namely primary data and secondary data. Surveys are conducted for primary data in the form of Total vehicles counting on the East Ring Road, Data on traffic volume surveyed for 2 days (6 and 10 August 2020), for 6 hours per day at 06.00 -08.00, 12.00 -14.00, and 16.00 -18.00 Moreover, to obtain the data it is necessary a way to collect it. Related to the problem, to obtain traffic volume data is by Manual Count, which is the traffic calculation simply, counting each type of vehicle through an observation point on a road. The calculation, capacity in Manual Road capacity Indonesia 1997 uses traffic volume of three types of vehicles, namely light vehicles (LV), heavy vehicles (HV), and motorcycles (MC). Heavy vehicles include buses and trucks or vehicles with a total wheel of more than 4 pieces. Light vehicles include passenger cars, common forces such as Bemo and taxi, pickups, car boxes, and small trucks. Motorcycling is all kind of a two-wheeled motor vehicle. The survey power required to record traffic volume is 3 (three) people on each road segment with PEN/pencil and paper equipment with a 15minute time pattern and by making bar marks on the table. Secondary data is also used to support the calculation of traffic performance with data on the population of District Sidoarjo in the year 2018.

Road Goemetrik Data
Geometric data is the data that contains geometric conditions from the road segment being researched. This data is the primary data obtained from a survey of road geometric conditions directly. The geometric Data of the Ligkar East Road section is as follows.

Traffic
The traffic composition that crosses the East Ring Road section is as follows. a. Motorcycle (MC), a two-or three-wheeled vehicle b. Lightweight vehicle (LV), a four-wheeled motor vehicle with two-axle is 2.0 -3.0 m (including Oplet passenger vehicle, Microbus, pick up, and small truck) c. Heavy vehicle (HV), which is a motor vehicle with two axles is more than 3.5 m, usually wheeled more than four (including bus, truck 2 as, truck 3 as, and truck combination) 3. Side Barriers Side barriers in this study, including : a. Pedestrian ( PED) b. Parking and slow vehicles (PSV) c. Slow moving vehicles (SMV)

Traffic Condition
Traffic flow data is the primary data obtained directly through field observation, this traffic flow observation is done for 2 days yes it is Monday and Thursday on August 6 and August 10, 2020. Observation time is adjusted with the busyness that occurred on the road of East Lroundabout, observations conducted during the peak hours of the assumption is at 06.00-08.00 at the peak of the morning, at 12.00-14.00 on the top of the day, and at 16.00-18.00 at the peak of the afternoon [6].
Observations are done for 2 hours per 15 minutes. Here the traffic flow data at peak hours obtained from the field, for overall traffic flow data can be seen in the appendix. 1. Survey results of traffic flows and side barriers: Point 1 morning Peak   2. the performance of the eastern periphery of Sidoarjo district in existing condition based on the value of the degree of Point 1 is approaching the standard limit of 0.61 where the standard limit set in Indonesia Road capacity Manual (MKJI) 1997 only 0.75 and Point 2 has exceeded the standard limit of 0.97 where the standard limit set in the Indonesian Road capacity Manual (MKJI) 1997 is only 0.75 3. For the results of the level of service that can be from the calculation then the level Of service or Level Of service that can be in the point 1 is = C (stable current speed and motion-controlled vehicles) and in point 2 is E (current unstable speed sometimes stalled demand nearing capacity) 4. Conducting socialization or counseling of traffic order in the form of traffic signs or sanctions in order not to cause a potentially infringing deed of traffic and reduce activities besides the road that can obstruct the visibility of the driver and will be able to enlarge the volume and capacity on the road segments 5.
