Abstract:
The city of South Jakarta is a dense metropolitan city because it has a high population growth rate. Due to this population growth, the city of South Jakarta has experienced additions, expansion of social facilities and infrastructure as well as transportation to serve the needs of its residents, one of which is the Lenteng Agung-West Tanjung Flyover Development Project. The infrastructure built has an impact on traffic congestion on the performance of the Lenteng Agung-Tanjung Barat road and Pasar Minggu intersection. The purpose of this study is to determine road performance and to know strategies that can be used to overcome the impact of traffic congestion. The method used in this analysis and discussion is based on the Indonesian Road Capacity Manual (MKJI), 1997 and conducts a field survey for the performance of roads and intersections without signals. The results of the research obtained on the performance of the Unmarked Intersection road are the largest traffic volume of the Unmarked Intersection which is obtained from the survey results on Friday 18 December 2020 and the peak hours are at 06.30-07.30 WIB With the degree of saturation DS = 0.66, the delay at the intersection is 10.85 sec / pcu and the chances of queuing are 36.97% -17.96%. In the analysis of the Lenteng Agung road section, the highest level of service was obtained on Monday, November 16 2020 in the morning at 07: 30-08.30, with a degree of saturation of 0.98 having a service level of E, which means the flow is unstable. Meanwhile, in the afternoon, 16: 00-18: 30 with a saturation degree of 0.53 and has a service level of B.Keywords:

In this study presents to study of traffic volume and Level Of Service at vejalpur cross road in Ahmedabad, which is one of the fastest developing city of India. Ahmedabad is a rapid growing city suffering from traffic jam. The increasing of traffic volume at unsignalised intersection has been arising problems like road accidents, conflicts and congestion. The objective of this study to analyze prevailing traffic condition at vejalpur cross road. The traffic volume count is carried out at intersection for each approach and regarding Level of Service calculated. In this study Traffic Volume Count is carried out by video graphic method. Due to mixed nature of traffic it gets difficult to accommodate all the sorts of traffic on these roads. The essential problem arises during the height hours of the day when the traffic volume is highest on the road. The data was analyzed for the peak hour of traffic.

Traffic is a major problem in the modern era with the increase in population there is the increase in the number of vehicles, road users which end in congestion of traffic. The static road infrastructure is almost the same and unable to cope with changes like congestion, unpredictable travel time, delay and road accidents that taking a serious shape and due to this there is need to control the road traffic with help of traffic control optimizer. In spite of measures being taken to migrate and reduce traffic, it becomes major concerned faced by the metropolitan cities during the planning of cities it has emerged as one of the main challenges for developing cities. To find out appropriate measures there is the necessity of identify magnitude of traffic congestion. The construction of new road or widening of existing road is not feasible every time it will result in additional traffic congestion the total available space within the city for the construction of the road, railway, and other transportation is restricted. This study focuses on the implementation of movable traffic dividers to solve the traffic congestion problem in metropolitan cities.

Urban road intersections are a major factor that influences the effectiveness of traffic flow systems.This paper is aimed at examining the performance of road intersections in the Lagos metropolitan area using the "Y-junction" of Oga-Ikorodu (Lagos, Nigeria) as the case study.The study examines the delay factors, time wastage and traffic conflicts.The study uses a reconnaissance survey, delay analytical tool, vehicle spot speed study and traffic volume survey to assess the level of delay, economic loss and traffic flow interruption.The study reveals that there are varying Levels of Service (LOS) obtainable at different times of the day on different carriageways, while Ayangburen Road records the best LOS of B in the morning, the afternoon and evening recorded C and D respectively.A different scenario holds for both Lagos and Sagamu as they record the worse LOS of E in the evening peak.In a related manner, the percentage of vehicle stoppage falls between 41.1%-87.8%indicating that vehicles tend to experience a stop scenario than not-stop at each approach especially during the peaks.It is therefore pertinent to note that the road intersection operates at a very low level of service especially during the evening peak when controlled by traffic wardens.It is therefore recommended that a Diamond-at-grade intersection be constructed in the area instead of the round-a-bout.The introduction of an automated traffic control system with full control of access and total removal of on-street parking will remove the road users' burden in that area.

A computer simulation is important for the analysis geometry of freeways and urban streets systems.Transportation specialists can study the formation and removal of congestion on roadways. Theintersection is one major cause that has a significant effect on travel time, delay, level of service, queues,stop, performance index, degree of saturation and capacity. The target of this paper research is toanalysis the geometry and intersection classification of traffic flow to provide useful information forengineers to design the roads with the shortest travel time and enhance the capacity of road networksand relieve the congestion in cities.The data required for the study were mainly collected from through video filming technique also thecalculation and evaluation are constructed with the aaSIDRA software in the 2011.

The problem with traffic congestion is particularly expressed in urban areas where possibilities for physical increment of capacity are limited or impossible. Significant in the approach to solving this problem is the usage of Public Transport (PT) and the implementation of various advanced control measures that can improve the quality of overall public transport system. The main objective of this research is to explore the possibilities of implementation of adaptive traffic control on signalized intersections giving priority to public transport vehicles through urban traffic network in the city of Zagreb. The possibilities of implementing public transport priority (PTP) technique in the city of Zagreb are analyzed because of specific traffic situations on defined corridors (location of stops, distance between intersections, etc.). With proper usage of PTP techniques (e.g. adequate detector positions, good estimation of PT vehicle arrival time at intersection) the total tram travel time can be significantly reduced. The Level of Service at intersection may be approximately retained because cross-street traffic demand was not ignored. According to technological level of traffic control system in the city of Zagreb, global implementation of PTP is not possible. So, for each intersection the PTP algorithm was developed separately, but mutual traffic influence of all intersections on the corridor was considered. The cooperative concept application within urban traffic control is considered as well.

Abstract Numerous regions in the city of Baghdad experience the congestion and traffic problems. The study area is located at Karkh side in Baghdad City. The geographical area situated among several streets; 14th July Street (section in Ring road No. 1), Demishq Street, Mansure Street and 14th Ramadan Street. The main intersections in these streets are; Shaljya Intersection, Demishq Intersection, Dilal Intersection, Gailani intersection, and Topji Intersection. The proposed road starts from the Gailani intersection and jointed with 14th July Street (Ring road No. 1) with length (1.9 Km). The study area is facing a low level of service during traffic congestion resulting from an inefficient and poor road network. The main purpose is to study constructing a new road to reduce the environmental and congestion impacts on the transportation system at selected roads. The percentages of expected generated traffic that will be serviced in the suggested rout are 23% and 52 % from the peak hourly volume counting in location 1 (Shaljya Intersection). On the other hand, at location 2 (Demishq Intersection), the percentages of generated traffic transported to the suggested rout are 22% and 23%. By using Highway Capacity Manual (HCM), the required lanes for the suggested road are 3 lanes for each direction. According to findings, construction of the suggested road is important to improve the road network in term the traffic and reduction the vehicle emissions at present routs.

In recent years, with the accelerating process of urbanization, the pressure of urban road traffic is increasing. The refined traffic design and precise traffic management are conducive to the development of urban roads. Taking the intersection of Yanta North Road and Youyi East Road in Xi'an as an example, aiming at the traffic problems existing in the intersection and the road section, this paper puts forward the reconstruction suggestions based on the refined traffic design concept. In this paper, a new signal timing scheme is calculated, and SNYCHRO software is used to simulate and evaluate the intersection before and after the reconstruction. The evaluation of the decrease of average saturation and the improvement of the overall service level of the intersection is obtained. This scheme can effectively reduce traffic congestion and provide reference for other similar urban road design.
