Illegal Driver Behavior at Signalized Intersections

University of Duhok (Issue: 2) (Volume: 22)

This paper deals with two common driving offensive cases at signalized intersections: 1-The sudden change in lane on the beginning of the green interval to pass the intersection using the right turning lane. 2-Theforced emerging through queuedvehicles passing T intersection on the through approach, always green lane.The objective of this study is to observe and count the percentages of those impatientdrivers on four intersections during peak hour period. The data was collected withinDuhok city at two intersections, for each of the above mentioned cases. Video camera was used to collect the flow of vehicles ineach case. Traffic counting was carried out on the video using thelaptop keys and EVENT computer program. Peak hour period for the four intersections was (5:00pm -6:00pm) according to a comprehensive previous study for traffic in Duhok city.The total hourly traffic flow was collected on the diagnosed approach. The percentage of the offensive drivers was collected relative to the total traffic flow at the approach during the same period.For the first case, the analyses of data shows that: The percentage of offensive vehicles to the total flow of the approach was 11% at Biraintersection. Larger rate was noticed at Mamintersection reaching 27%. Adding painted street markers did not change the tendency to break the regulations.For the second case, the data was collected at two intersections, namely Safin, and Sulav. The percentage of the offensive vehicles waswithin 20% for the two intersections.Off peak period observations did not show any obvious change in drivers behavior.

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.

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.
