Each student must submit a laboratory report for each project on due date.
You will work as groups. However each student mustsubmit his!her own
report.
"opying others# reports is absolutely not allowed. It may result in a 0E#'
grade in the project.
You must show your calculations clearly in the report.
Each report mustcontain a discussion and conclusion section. $his section
may include discussion of the theory data analysis conclusions of the project
observations and comparison between the e%perimental values and e%pected
values. &iscussion of the sources of error may also be included in the
discussion.
You should read the project before you come to the class with reasonable
understanding of the theory and the idea behind the e%periment.

Intersection Analysis an Control
&ac6groun4
It has been noticed that traffic congestion in ablus and in other urban areas in the
?est Cank are most severe at key intersections. Proper intersection design and
control is very important in assigning right of way improving traffic flow through the
intersection and enhancing safety.
Intersection design features include number of lanes lane widths proper
channeli;ation curb radii etc. Intersection control features include proper
installations of traffic control devices including signs and markings. >t specific
intersections and if warranted traffic signals must be installed. $o evaluate the
performance of an intersection capacity and level of service analysis are usually
performed.
Fiel Stuy4
$his study focuses on intersection design and control at key intersections.
First4intersection approach geometries have to be identified. Ne5t4an inventory of
control measures at the approaches and of e%isting traffic control devices at the
vicinity of the intersection is to be performed. $his in addition to the peak hour traffic
volumes at the intersection considered which you have performed in ab. >ss. o. 3
