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

or will be supplied form a basis for proper design and control.

#e7uire4



-. &raw the intersection at a proper scale showing all e%isting geometric and

control features including traffic control devices.

/. >naly;e the appropriateness of the current geometric and traffic control

devices.

1. (uggest modifications and make proper geometric design for the intersection

including channeli;ation and draw using a proper scale.

3. (uggest modifications to traffic control and show suggested traffic control

devices for the intersection.

4. "heck whether a traffic signal is warranted.

5. If a traffic signal is to be installed. &esign the signali;ation plan showing

phases cycle length intervals split etc.
