Investigating The Causes of Traffic Accidents for Duhok - Zakho International Road

University of Duhok (Issue: 2) (Volume: 21)

Traffic accidents are considered as one of the main causes of death in the world. In order to reduce number of accidents, traffic safety refers to the methods and measures used to prevent road users from being killed or seriously injured. In Kurdistan, more than 1,000 inhabitants are killed in road accidents every year and about 200,000 are injured. This study focuses on investigating the reasons of accidents occurring along Duhok-Zakho international road, and identification of high accident locations (HALs) using accident number, accident rate and rate quantity control methods. Data such as the type of accident, the causes for each type, the traffic flow and geometric design have been collected for nine segments of the road from 2013 to 2016. The results indicate that the rear-end collision is the highest frequency among other types of accidents and the year 2014 has the highest number of accidents. There is an urgent need for specific countermeasures to be implemented (e.g. installing more speed limit camera, lane marking). Hence, this study has shed light on this road to find the optimum solution for such safety problem.

Coordination of Traffic Signals on Arterial Streets in Duhok City

Civil and Environmental Engineering (Issue: 3) (Volume: 12)

The increase in levels of traffic congestion along urban signalized arterials needs efficient traffic management. The application of traffic signal coordination can improve the traffic operation and safety for a series of signalized intersection along the arterials. The objective of this study is to evaluate the benefits achievable through actuated traffic signal coordination and make a comparison in control delay against the same signalized intersection in case of being isolated. To accomplish this purpose, a series of eight signalized intersections located on two major arterials in Duhok City was chosen for conducting the study. Traffic data (traffic volumes, link and approach speeds, and passenger car equivalent) were collected at peak hours. Various methods had been used for collecting data such as video recording technique, moving vehicle method and manual methods. Geometric and signalization data were also collected for the purpose of the study. The coupling index had been calculated to check the coordination attainability, and then time space diagrams were constructed representing one-way coordination for the intersections on Barzani and Zakho Streets, and others represented two-way coordination for the intersections on Zakho Street with accepted progression bandwidth efficiency. The results of this study show great progression bandwidth of 54 seconds for east direction coordination and 17 seconds for west direction coordination on Barzani Street under suggested controlled speed of 60 kph agreeable with the present data. For Zakho Street, the progression bandwidth is 19 seconds for east direction coordination and 18 seconds for west direction coordination under suggested controlled speed of 40 kph. The results show that traffic signal coordination had led to high reduction in intersection control delays on both arterials.

Geometrical Design Errors in Duhok Intersections by Driver Behavior

University of Babylon, Engineering Sciences (Issue: 5) (Volume: 26)

In many situations,drivers if certain of the absence traffic monitoring systemtend to shorten their driving paths and travel time across intersections. This behavior will be encouraged if the geometrical design suffers from mistakes, or the geometrical design and road conditions make it harder for drivers to follow the correct routes.Sometimes the intersection arrangement is confusing for the driver to distinguish the right from the wrong track.In this study,two sites with large number of driving mistakes were noticed. One siteis a roundabout within the university of Duhok campus. The other isthe intersection just outside the University of Duhok eastern maingate. At both sites,the geometry is very confusing and encourage driving mistakes.The university roundabout which was the first site investigated,was not properly designed encouraging wrong side driving. Many traffic accidents took place at this roundabout.Wrong side driving reaches32% at peak hourin one approach. This was reduced to 6% when temporary divisional island was installed. The other approach hasa 15% wrong side driving and no remedy could be done to it.At the intersection near the university gate, wrong side driving reaches 56%of the traffic emerging from the main gate at peak hour. This was reduced to 14%when drivers are guided through direction sign. This percentage was reduced further to 9% with standing policeman. Key Words:Geometrical, Design, Intersection, Roundabout, Behavior, Wrong, Driving.

Effect of Aggregate Maximum Size upon Compressive Strength of Concrete

University of Duhok (Issue: 1) (Volume: 20)

Aggregates form 60% to 75% of concrete volume and thus influence its mechanical properties. The strength of normal concrete is affected by the maximum size of a well-graded coarse aggregate by two opposing ways. Concrete mixes containing larger aggregate particles needs less mixing water than those containing smaller aggregates. On the other hand, the smaller size aggregates give larger surface area for bonding with the mortar matrix. This study is a trial to cover these two points with testing three different useable concrete mixes in Kurdistan Region–Iraq which are 1: 1.5: 3, 1: 2: 4 and 1: 3: 6 (Cement: Sand: Gravel). In each mix, five maximum aggregate sizes were used which are 9.5 mm, 12.5 mm, 19mm, 25mm and 37.5 mm, the consistency of the all mixes is fixed for slumps of 25-50mm. According to the test results it is concluded that in general the compressive strength of concrete increases when the maximum size of aggregate decreases and the maximum aggregate size strongly influences the concrete strength. Test results also show that the optimum concrete strength is reached by using aggregates of 9.5 mm maximum size. We further concluded that for a specified strength, an economical mix can be produced by decreasing the amount of cement and using an appropriate maximum aggregate size.
