Assessing Level of Service, Capacity and Future Optimization of Roundabouts in Rajshahi City Using Sidra Intersection

This study investigates traffic flow challenges at the bustling Mintu Chattar roundabout Situated in Laxmipur Mor, Rajshahi, Bangladesh. Located in close proximity to a hub of hospitals and medical establishments, this intersection routinely witnesses traffic congestion, becoming a familiar occurrence in the area. From dawn to dusk, traffic officers are required to step in to manage the traffic flow of countless individuals commuting to hospitals, workplaces, educational institutions, and other destinations. Our capacity analysis using Sidra Intersection software reveals significant bottlenecks, particularly during peak hours, necessitating traffic police intervention due to inadequate control measures. The research identifies key contributing factors: insufficient entry and circulatory lanes, uneven traffic distribution, and high overall traffic volume. A detailed case study of the south leg highlights the severity of the situation, with Level of Service (LOS) dropping to F during evening hours, resulting in long queues (over 61 vehicles) and delays exceeding 82 seconds per vehicle. The integration of the design life model from SIDRA software has also illustrated the correlation between Level of Service (LOS) and capacity with the projected rise in traffic volume for the next five years. In order to improve traffic flow efficiency, the study proposes exploring design optimization of the roundabout. This includes investigating the impact of geometric redesigning, such as gradual expansion of approach lanes width, on capacity at the roundabout leg, considering both existing and future traffic scenarios.

Performance analysis, evaluation, and improvement of selected unsignalized intersection using SIDRA software – Case study

Abstract Significant social, economic, and environmental costs are associated with traffic congestion. The effectiveness of intersections makes a substantial contribution to the effectiveness of entire road networks. The three-leg at-grade Al-Husainea intersection, located 20 km from the center of holy Karbala city in Iraq, is subjected to serious congestion, resulting in an increase in delay time, reduction in capacity, and bad level of service (LOS). Therefore, it is essential to use advanced software tools to ensure that the current intersection can be controlled, evaluated, and improved. So, the major goal of this study is to use SIDRA, an acronym for signalized and unsignalized intersection design and research aid, software to evaluate the LOS of the Al-Husainea intersection, in which the traffic is assessed using the current LOS. LOS, delay time, and degree of saturation were the criteria utilized to evaluate the traffic flow performance. SIDRA is also used to assess benefits as a result of suggested changes in the design of particular junctions. The first stage is to gather field data regarding traffic volumes utilizing a method of traffic volume gathering. From 7 am to 6 pm, the SIDRA program gathered data for a full 7 days. The results showed that the LOS for the Al-Husainea intersection in the Al-Husainea arm is F, with an average delay of 52 s per vehicle and a saturation level of 0.86 v/c. Finally, it was determined that the Al-Husainea intersection needs additional improvements based on the study and findings from the SIDRA program, and some remedies are suggested in this study to improve the intersection traffic flow.

Turbo-Roundabouts as a Tool for Enhancing Urban Efficiency and Safety: A Case Study

Traffic jams occur when a volume of traffic influx produces a demand for space more significant than the road allows. Numerical field data addressing vehicle counts and statistical computer simulations are vital tools in determining a road’s serviceability and traffic level. Both have been utilized in this study. The primary objectives of this study are to conduct a comprehensive analysis of the traffic flow, measure the Level of Service (LOS), travel time, degree of saturation, delay time, and articulate a strategy to reduce traffic congestion at roundabouts. The study unequivocally concluded that the LOS at the eastern entrance is F level. The data on the number of vehicles that pass through the roundabout at the eastern entrance of Benghazi were recorded during the peak hours from (12:00 to 1:30) p.m. The mixed traffic stream was then converted to passenger car units (PCU) to be homogenously equivalent. The results of the systematic analysis of the gathered data indicate that the roundabout at Benghazi’s eastern entrance requires further development to alleviate the dire traffic conditions. To run an accurate simulation, the existing road layout was surveyed using surveying instrumentation, and the results were used to build a model. Acceleration and deacceleration lanes were proposed to improve the roundabout performance and reduce congestion. Then, the roundabout expansion proposal was introduced into the simulation to study its effectiveness in reducing traffic jams. The data were analyzed and tested using SIDRA software. The Level of Service at the roundabout’s lanes showed tremendous improvement as the Level of Service varied from A to B levels compared to the current LOS level of F.

Optimizing Performance at Signalized Intersections through Signal Coordination in Two Intersections of Nepal

Intersections in urban areas can often cause significant traffic delays due to the multiple directions of traffic flow. The Kathmandu Valley experiences chronic gridlock and congestion. This study aims to improve traffic flow at two busy intersections (Kanti Children's Hospital and Shital Niwas) in Kathmandu Valley, Nepal through evaluation of the existing traffic flow condition and reducing delays and queues using various alternatives and including signal coordination. A survey was carried out to collect morning peak hour traffic volume and geometrical features of the two intersections and developed a signalized intersection model in SIDRA software. The model was validated based on observed and modelled queue lengths for each approach, and the existing performance of the intersections was evaluated. Various alternatives were then developed to improve the performance of the intersections. Results showed that coordinating the signal systems significantly reduced the average delay time and maximum queue length at both intersections. Specifically, the average delay time was reduced from 106 seconds per vehicle to 26.5 seconds per vehicle at the Shital Nivas intersection and from 43.1 seconds per vehicle to 21.7 seconds per vehicle at Kanti Children's Hospital intersection. Similarly, the maximum queue length was reduced from 744.7 meters to 122 meters at the Shital Nivas intersection and from 456.2 meters to 147.7 meters at Kanti Children's Hospital intersection.

Performance Evaluation and Improvement of Main Road Intersections in Al-Bayda City Using Sidra Software

Intersections are one of the most crucial parts of urban transportation systems since they actively contribute to developing strategies to reduce traffic congestion. Congestion is one of the major issues that intersections face as a result of the growth in traffic, which cause lower service levels and longer waiting time. The main goal of this study was to evaluate the current traffic flow and Level of Service (LoS) at four signalized intersections at peak hours in the city of Al-Bayda utilizing sidra software. In addition, comparing the performance of traffic flow during the morning and evening peak hours at the selected intersections. The results revealed that the level of service of the four intersections was very low and ranged between F and D, which indicated that the delay time was very high, therefore, an improvement to these intersections was necessary. After exploring various alternatives, the level of service increased to B and D levels, which make the delay time acceptable in these intersections. In the morning period, the average delay time decreased by 43.6, 44.3, 32.3, and 42% for intersections no.1-4 respectively. In the evening period, the average delay time decreased by 45.8, 69.5, 57.5, and 52% for intersections no.1-4 respectively.

Optimization of Delay at Isolated Signalized Intersection Using HCS2010 and SIDRA Intersection 8 Software: a Case Study

Signalized intersections play a significant role in regulating the traffic stream in urban transportation networks. Extensive delay increases travel time cost and reduces Level Of Service (LOS). This study is conducted to determine delay at five isolated signalized intersections in Erbil city, Iraq using two software to improve intersection performance. The Highway Capacity Software (HCS+T7F) and Signalized and Unsignalized Intersection Design and Research Aid (SIDRA Intersection 8) software. An optimizing model following the Genetic Algorithm (GA) has been applied to optimize the signal cycle time using HCS2010(HCS+T7F) and SIDRA software in order to minimize delay at signalized intersections. The average delay value for all the intersections has been reduced after optimization using SIDRA delay model, which represents 21% reduction. On the other hand, by using HCS2010, the value has been reduced by 29% reduction, which is still higher than average field measured delay. In addition, SIDRA optimizing model has a lower optimum cycle time compared with HCS2010 optimize model. For better performance, the intersections should be optimized depending on the SIDRA.

Evaluating the Performance of Traffic Flow using SIDRA for Roundabouts in Ipoh, Perak

Due to rapid development and urbanisation, the traffic systems in Perak are developing and continuously growing in numbers. Evaluation of junction concerning capacity and safety is very important since it is directly related to delay, level of service, accident, operation cost and environmental issues. Traffic congestion happens due to delay and reduction of average speed during AM Peak hours at two roundabouts. This study aims to improve the traffic flow by determining the LOS at two different roundabouts. A traffic study was conducted at “Bulatan Bahagia” and “Bulatan Sultan Iskandar” in Ipoh. Sidra 5.0 application was used as an alternative to Highway Capacity Manual to analyze the junction and LOS performances. This analysis was carried out using SIDRA Software 5.0 to determine the LOS at “Bulatan Bahagia” and “Bulatan Sultan Iskandar” in Ipoh. This study provides recommendations to improve the roundabout performance. The result shows the improvement in the level of service from LOS F to LOS B and from LOS F to LOS D. The percentages of reduction for delay were 2 % and 5% respectively. The finding shows that speed on road has a direct correlation with traffic congestion. The speed improves up to 57 % and 20 %. The analysis indicates that Sidra application utilisation gives the best alternative design for intersections and improve the LOS due to sustainable traffic demand on both upstream and downstream roundabouts.

Comparative Study of Operational Performance between Roundabout and Signalized Intersection Using Sidra Software: A Case Study of Addis Ababa City

Abstract: Traffic signals and roundabouts controls are commonly used in several at-grade junctions in urban areas for maximizing traffic efficiency and safety by separating traffic movements in time. The intersection performance is measured by comparing the parameters like- capacity, degree of saturation, delay, queue length, fuel consumption, operating costs and emission, etc. This research paper provides a comparative study of operational performance between a roundabout and signalized intersection at Gergi-Imperial. The traffic data on all approach of the intersection were collected by video camera during the most congested days of the week. The traffic volume obtained in different classes of a vehicle was converted to uniform vehicle fleet by the passenger car equivalency factor. The geometric data for the selected intersections were measured manually. Data analysis and processing were performed using SIDRA (Signalized and Unsignalized intersection Design and Research Aid) intersection software to compare the traffic flow condition at the intersection. The performance measures such as Average delay, Degree of saturation and Level of service at each intersection were interpreted for comparison. The capacities of the signalized intersection were found to be higher than the capacities of roundabout. Signalized intersection was found to be better than the roundabout in terms of the degree of operational performance.

Improvements of some roundabout Intersections using capacity model Analysis

Several methods of analysis have been proposed to analyze the ability of vehicles to rotate and manoeuvre during roundabout intersections. Some models have been using formulas and calculations for extracting the results manually, while other models have been used to use the engineering software for the model. Given these differences, it may not be clear how best to use them in a particular situation. When comparing methods of capacity analysis, it will be useful to know how the various techniques are performed across a set of approaches Conflicting volumes. This paper reports on the ability of techniques to rotate multiple pathways based on maximum entry and exit traffic volumes using several methods of analysis. The research study the capacity model for some roundabout intersections in Hilla city, they are, (Al- Mohafada, Al-Saia and, Sahat Abn-Idreas). The capacity equations have been examined using some of the software programs, Highway Capacity HSC 2010, (Signalized Intersection Design and Research Aid) SIDRA, (macroscopic analysis and optimization software application). Synchro 10, to reach the best solutions to describe traffic capacity for each intersection within the study area. Data have been collected according to field survey include traffic volume for different types of vehicles and pedestrians, within antemeridian & post-meridiem (a.m&p.m ) Peak Hour Volume (PHV), Number of lanes, lane width, median width, shoulder width and pedestrians crossing included too, using video technique method. Comparing the capacity for each approach and intersections using the above software programs on the bases of several variables: V/c, delay time, LOS and queue length. It was concluded that all intersections appear with the level of service LOS (E–F) according to (V/c)>1 and increase the delay time. Also, LOS improved from (F to C) when adding one lane for each approach for Al-Mohafada roundabout intersection according to output SIDRA software, as well as it was found that SIDRA software program gives significant results on a capacity model due to take into account the geometric characteristics of the intersections and pedestrian movements and crossing. Likewise, the Syncro program creates simulations of the roundabout with the traffic volumes entering the roundabout intersection, through which it identifies the conflicting points inside the circular intersection and shows the delay in each approach and also shows the queue for each approach.

EVALUATION OF GEOMETRIC AND BEHAVIORAL FEATURES OF ROUNDABOUT BY USING SIDRA SOFTWARE

Computer simulation can be of high importance to analysis geometry regarding the signalized roundabouts and intersections that are related to systems of urban streets. The major goal of the presented research is analyzing geometry as well as the intersection classification that is related to traffic flow, as well as enhancing the capacity related to intersections for road networks, also relieving city’s congestions. Data on number of vehicles passing through Mudaffar roundabout have been recorded through the author of the presented study from seven in the morning to three after noon for 4 days. Sidra software was adopted to analyzed the data. The results have indicated that the level of service (LOS) regarding the present conditions in the discussed roundabout has been F, and with average delay (303.6 sec/veh). There are two proposals will be used to the developing of the roundabout. The best results indicated that the LOS for present condition of Mudaffar roundabout is C with (26.4 sec/veh) of average delay.

The Environmental Impact Reduction of Highway Traffic Congestion using Sustainable Tool

The global environment is mainly affected by the increase in traffic volumes at intersections in terms of air pollution. Serious solutions are needed to avoid air pollution specially in the crowded in congested intersections. Recently, the concept of sustainability and sustainable tools has been found to minimize congestion and excess emissions of the gaseous pollutants problem to some extent. The current study focused on a critical intersection in Baghdad city which is Shaab-Selekh intersection. Shaab-Selekh intersection can be classified as the most congested intersection for its high traffic density, especially in the morning and afternoon peak hours. This study evaluates the level of service, estimating the environmental impact (air pollution) due to traffic congestion, and propose set of sustainable tools to reduce air pollution associated with reduced congestion traffic. In order to reach these objectives, many factors were considered such as traffic volumes and counting time periods (morning and afternoon peak hour) in December 2018 by (video recording technique and manual counting). In addition, SIDRA software version 5.1 was used to evaluate the level of service for the intersection and indicated that it equal to LOS F, and to estimate air pollutants (CO2, HC, CO, NO2). This study will also compare air pollutants for the study area with international standards and the congestion cause negative impacts on the environment.

Existing Road Performance of the New Development of Sibu Central

The proposed development of Sibu Central hinges on the fact that it attracts high number of visitors from all over Sarawak. The development of Sibu Central would definitely improve the surrounding areas in future as Sibu Central will be one of the landmarks for Sibu. This development therefore will automatically generate more road traffic which will affect the performance of the existing road. The performance of the existing road was evaluated by two signalized intersections surrounding the proposed development of Sibu Central. It was carried out in order to determine the current traffic volume data, upon the completion of Sibu Central and 5 years after the development was completed. The road performance of Intersection 1 and Intersection 2 was analysed by using Sidra software. It was found that the existing road was still within the satisfactory performance, as the Level of Service (LOS) was in the range of LOS A until LOS D. This was due to the current traffic volume that was still under the capacity of the existing road which also influenced the satisfactory result for Volume by Capacity (V/C) ratio, average delay and queue length of all directions in Intersection 1 and Intersection 2. This result will not be adequate as the capacity of the road still remains unchanged due to the fact that the traffic volume keeps on increasing every year. The deterioration of the existing road in Intersection 1 and Intersection 2 was established in this study based on the performance of LOS, V/C ratio, average delay and queue length.

Simulation of traffic flow in unsignalized roundabout using SIDRA software evaluation in Baghdad City

For evaluating the urban roads as well as the express ways, the simulation software are considered to be of high importance. The experts of transportations are concentrating on dissemination and arrangement regarding roadways’ traffic jams. The main aim of this present work is to analyze the present situation of traffic in Wahran round-about Baghdad/Iraq/according to certain consistent traffic count using SIDRA software through calculating the level of service, delay time, travel time, and degree of situation. The author of his work recorded the number of vehicles passing Wahran Roundabout for two peak hours, morning peak hour from (7:30 to 8:30 a.m.), while the evening peak hour from (5:30 to 6:30 p.m.). The performance related to the present intersections has been assessed through the use of a simulation model. The results have indicated that the level of service (LOS) related to Wahran Round-about is F of (111.3 sec/veh) average delay and degree of saturation has been (1.737 v/c).

A Case Study on Roundabout under Congestion: Proposal to Improve Current Traffic Operation

Roundabouts are progressively being utilized on occupied arterial streets for traffic quieting purposes. Be that as it may, on the off chance that one indirect leg is close to a conveyance center point, for instance, stopping territories of strip malls, the passage traffic volumes will be especially high in pinnacle hours. On the basis of the Al-Turkman Roundabout, which is one of the most important roundabouts in Baghdad city, linking the areas of east of Baghdad to the city center in the area of Bab Al-Moatham. This area is characterized by its high traffic volumes (congestion), especially at peak periods causing a low level of service (LOS) with increased travel time delay, costs, and CO2 emissions. The research relied on the use of the SIDRA software to assess these variables by collecting traffic volumes in this area. The research proposed a series of planning procedures which are divided according to serial time scales. These planning procedures are to address the problem of congestion and traffic jams in the area, improve the level of service, and reduce travel time, cost and CO2 emissions. The research concluded that the application of the planning proposals in the study area has improved the level of service from E and F to C, reduced travel time by 16%, reduced costs by 25% and reduced CO2 emissions by 29%.

The Cause, Effect, and Possible Solution to Traffic Congestion on North Nicosia Roads, Cyprus: Experimental and Theoretical Approaches

Objectives: To analyze traffic congestion at North Nicosia intersections in Cyprus. Eight intersections in North Nicosia ware considered and analyzed using experimental and theoretical approaches. Methods/Statistical Analysis: Field data were collected and analyzed using SPSS software to find the most congested intersections in North Nicosia. Moreover, this paper presents a comparative analysis of the operational efficiency of intersections under a range of traffic conditions with different volume and turning ratios using SIDRA software. Average delay time, the degree of saturation, Level Of Service (LOS) and travel speed were used represent the operational efficiency of the intersections. Furthermore, SIDRA software produces many Measures Of Effectiveness (MOEs) of which four (HC, CO, NOX, and CO2 ) were chosen for analyzing the environmental impact of intersections. Findings: Based on the field data and SPSS results, it is found that Gönyeli, Göçmenköy, and Yenikent intersections are the most congested intersections in North Nicosia. Results of the current case demonstrated that the level of service for the intersections in North Nicosia is F with average delay and degree of saturation ranged from 10 to 51 second/veh and 0.42 to 1.03 veh/c, respectively. It is concluded that North Nicosia intersections need further developments to reduce traffic issues. Based on SIDRA results, it is observed that LOS of the proposed intersections was B for Gönyeli, D for Göçmenköy and C for Yenikent intersections. In addition, statistical tests showed that the decrease in MOEs in all proposed intersections was statistically different from the emissions that occurred in the current cases. Application/Improvements: The proposed intersections could be used as a viable alternative to cut down vehicular emissions, making intersections more environmentally friendly and reducing the traffic issues.

Turbo Roundabout Usage in Lieu of Conventional Roundabouts for the Jordanian Traffic Conditions

The main objective of this study is to check the possibility of upgrading at-grade roundabouts to Turbo roundabouts considering the Jordanian driving conditions. It is also to check how such upgrade is going to affect performance measures of the studied areas including safety, capacity, queue length, delay, and level of service (LOS). Thus, three roundabouts were selected and analyzed using SIDRA software under off-peak, morning peak and evening peak traffic conditions to obtain the actual capacity, queue length, delay, and LOS values under the current design. Then two designs were applied for each roundabout according to Dutch design guideline manual using TORUS software by changing inner radius and opening width. The generated designs were analyzed using VISSIM software under the original traffic conditions, to evaluate the effect of introducing turbo roundabout system as a replacement to the conventional roundabout system. The results of this study indicate that turbo roundabouts offer higher capacities, less delays and better LOS compared to existing intersections. In addition, introducing turbo roundabouts might offer higher safety levels than conventional roundabouts; as conflict points were reduced from 32 on two-lane conventional roundabouts to only 12 on the proposed turbo roundabouts. Consequently, reconstruction of intersections was warranted.

Performance Evaluation of Grade Separation Within the Selected Major Intersection in Addis Ababa City

Urban City Traffic Management introduced various remedies to decongest traffic and to reduce the severity of accidents, such as providing traffic signal controls at the intersecting roads at different levels, or grade separating the traffic movement towards different directions. One type of grade separation is Road Underpass or Flyover. The construction of Road Underpass or Flyover poses some doubts whether it is effective or ineffective on the point of views of the travelers or motorists. It is for this reason that this research sought to evaluate the performance and effectiveness of Road Underpass structure on traffic flow at the major intersection, specifically the Wellosefer intersection in Addis Ababa City. The primary data used the existing traffic volume recorded between 7:00 AM – 6:00 PM from Monday to Friday. While the secondary data obtained from the Consulting Office before the improvement of Wellosefer intersection, including the previous study, which served as the control analysis for the research. From these data, the analyses provided results on vehicle travel time and delay for a case before and after improvement of the intersection. SIDRA Software was used to analyze the traffic conditions of the intersection. Based on the findings of the study, a case before Improvement of Wellosefer Unsignalized T-Intersection indicated with an average delay of vehicles of about 535.7 seconds, and a travel time of vehicles of about 574.7 seconds. On the other hand, a case after Improvement of Wellosefer intersection, three alternatives considered; such as 1) Signalized T-Intersection, 2) Roundabout, and 3) Road Underpass with Roundabout at the upper level. The results of the first alternative showed the Signalized T-intersection indicated an average delay and travel time of 344.3 seconds and 365.0 seconds, respectively. It means, there could be a reduction of 15.4% in average delay if signalized intersection implemented. The second alternative, a case of Roundabout using the same traffic data at current condition, the results indicated the motorists and commuters would be experiencing an average delay of about 355.8 seconds and average travel time of 390.0 seconds. The third alternative considering Road Underpass with Roundabout at the upper level, the results revealed that there was a significant reduction in average delay of vehicles of about 42% from the Unsignalized T-Intersection. Comparing this result with the Signalized intersection using the same traffic data, it showed that there was a significant decrease in average delay. Therefore, the findings of the study, a combination of Road Underpass and Roundabout at the upper level as in the case of Wellosefer intersection performed well than the other traffic control design alternatives.

Simulation of traffic flow in unsignalization intersection using computer software SIDRA in Baghdad city

Computer simulation is a vital means for the examination of expressways and urban lanes and streets. Transportation experts concentrate on the arrangement and dissemination of traffic jams on roadways. The objective of this study is to calculate and analyses the travel time, delay time, degree of saturation, and level of service and travel speed in Jordan intersection in Baghdad, Iraq using Sidra software. The number of vehicles passing Jordan intersection was recorded by the author of this work from 7am to 3pm for four days. A simulation model has been used to assess the performance of the current intersection. Results demonstrated that the level of service (LOS) for Jordan intersection is D with (35 sec/veh) average delay and degree of saturation (0.996 v/c). It was concluded that Jordan intersection needs further developments like using intelligent transportation system application (ITS) to regulate traffic signals, whereby reducing traffic jam, using closed circuit TV (CCTV) might assist traffic office in identifying jam point to reduce traffic jam.

A Study of the Flyover-Bridge Intersection – Improved Junction

To reduce a traffic congestion at an at-grade intersection near a big city, one method is construction the special bridge at the old junction in two directions on one of the main highways. It facilitates the traffic volume in the directions of the bridge, but the infrastructure cannot fully solve all of the problems especially on the secondary road. Under the bridge, although it relieves the traffic congestion at the crossroad, still uses the same control similar to the situation “before” such as the fixed time control plan of the traffic signalization. After controlled by this method, it was found that about 30-35% of all traffic volumes diverted to the bridges, and time delay reduced to 30% over the same period. This research is one part of author thesis work, presents the issues that still be found in the existing flyover area and suggesting improvement more benefit such as creating a new cycle phase time and improving the physical area. The SIDRA software is used to determine and point out the appropriate fixed time plans, and using the process of a Road Safety Inspection (RSI) to audit on fields and presents some serious of the traffic problems.

Evaluating the Performance of Traffic Flow in Four Intersections and Two Roundabouts in Petaling Jaya and Kuala Lumpur Using Sidra 4.0 Software

Delays represent one of the indirect costs in terms of frustration, loss of time and discomfort to the drivers. On the other hand, it represents a direct cost in terms of fuel consumption/wastage on road networks during idleness and inactivity. Extreme delay at signalized intersections reflects the incompetence in the signal timing because of consecutive signalized intersections on the particular site. The traffic parameters performance is not a feasible method or practice. Furthermore, one of the significant ways to improve the performance of the network is by coordinating traffic signal in intersections. This study was done to highlight the ability of improving the level of service (LOS) of four intersections; two of them with four legs and two with three legs as well as two roundabouts in Kuala Lumpur and Petaling Jaya using SIDRA software version 4.0. In addition, the study aims to compare the results between each peak hour in terms of percentage of change in the variables and the delay. Moreover, consideration of geometric delay should be taken into account when comparing delays in peak hours in the morning and the evening peak hours. The results obtained show that the morning period is better than the evening period for the value of delay, queue, journey time and speed that was obtained from practical measuring in the study area. The average reduction of delay in the study area before and after optimization of SIDRA software is from 3489 Sec to 1571 Sec in the morning period as well as 5093 Sec to 1663 Sec in the evening period. The percentage of reduction was about 45% and 33% -respectively.
