3.0 APPARATUS

Stopwatch, paper and pen (to record data), safety vest

4.0 PROCEDURE

1. The site location is identified and traffic movements for the identified intersection are

sketched.

2. The data collecting sheet is prepared before conducting the test.

3. The numbers of vehicles turning left, right and go straight at selected approach is

counted. Typical duration of interval is 15 minutes.

4. The data is collected until time duration of one hour is achieved.

5. The data collected is analyzed and level of service for all direction is determined.

5.0 RESULT AND ANALYSIS

A non-signalized T-junction in front UMS library is chosen as our assessment location to

evaluate the suitability of traffic control and safety.

Afternoon 34 213 130 377

Evening 66 135 100 301

From the table above, the total vehicle volume for afternoon session is the highest followedby evening session. The traffic flow is the lowest during morning session because the

assessment is conducted on Sunday. Hence, peak session which is the afternoon session is

chosen when analyzing the data collected.
