1.0Introduction. Running speed studies era conducted over a specified route for determining quality of service between the alternate routes. The rate of movement of a vehicle in distance per unit of time also known as speed. The common unit is km/hr. running speed is calculated by dividing the total distance by the total running time (only the time vehicle is in motion) for the route. All stop-time delays are excluded.

2.0Aim of Experiment. The objective of the study was predetermined as: a) To observe the pattern of running speed trend.

3.0Apparatus. The equipment used in this experiment is; a) Stopwatch

4.0Method i)

The study area was selected and the location preferably is a straight stretch section of road (100 meter). Point A and point B

was marked as the beginning and end of the test section ii)

respectively. There at least two members at each point. One more point was

iii)

added that is point C at the junction to set the delay time. Select the position from where the drivers will not be aware that

iv)

their vehicles are being recorded. Each observer records the last three or four digits of the plate number of each car that passes, together with the time at which

v)

the car passes. The delay time was observed and recorded (vehicles stopped at

vi)

traffic light or etc). Match the times of arrival at the beginning and of the test section for each vehicles number recorded. The difference between these times was recorded as the travelling time of each vehicle (minus delay/stop time if applicable)

OF VEHICLE

i) Running speed= total distance Total time Total distance from point A and point B in meter (42.86m) Total time is difference between point A and point B exclude stop time.

ii) Average running speed = 60.91 ÷ 10 = 6.091 m/s

6.0 Discussion From the experiment, we conduct this experiment to know the number of vehicular conflict and also reduce delay. This type of traffic signal is traffic actuated signal, the operation of this type of signal is varied according to the demand of traffic as register by the actuated of vehicle or pedestrian detector at one or more approaches, the traffic signal indication are not fixed length, but is determined by and confirmed within certain limit to the changing traffic flow. Sometimes, certain interval may be omitted when there is no demand. The problem that we faced during the experiment is we cannot ensure when the vehicle is straight way. Sometimes that vehicle is turn to the left or right or make a U-turn and does not give signal. From the experiment we could know how to solve traffic conflict and time sharing solution that is to allow right of way for particular movement at a particular time. Besides, space sharing solution was practiced to convert crossing conflict into weaving conflict.

7.0 Conclusion By doing this experiment, we achieve the pattern of running speed at Jengka City Centre main junction. We can conclude that the two route of the junction have more numbers of vehicles compare to another two route. This situation gives the cause of delay effect. Some vehicles take time to pass the junction. From research that we had made, we suggest the installation of the traffic light at this junction, The proper traffic signal design must be construct in way to produce smooth running speed pattern.
