Determination Of Headway And Average Travel Speed Of Vehicles
[Case study of post office-Kwara State Polytechnic permanent Site Car park Road]

CHAPTER ONE
1.0    INTRODUCTION
The determination of headway and average travel speed on a road network cannot be over emphasized as concerns the transportation. Headway and average travel speed are among the imperative parameters to be mentioned in the consideration of traffic flow. The efficient evaluation of headway and average travel speed is important for their contribution to the effectiveness of road network functionality therefore adequate management practices are needed.
Headway is a measurement of the minimum possible distance or time between vehicles in a transit system. It is commonly measured as the distance from the tip of one vehicle to the tip of next one behind it, expressed as the time it will take for the tracing vehicle to cover that distance.
Headway is a key input in calculating most overall route capacity of any transit system e.g the route of Ilorin post office to the permanent site of Kwara state polytechnic Ilorin.
Headway spacing is selected by various safety criteria, but the basic concept remains the same – leave enough time for the vehicle to safety stop behind the vehicle in front of it.
The safety stop criteria has a non obvious solution, however, if a vehicle follow immediately behind the one in front, the vehicle in front simply cannot stop quickly enough to damage the vehicle behind.
1.1     STATEMENT OF THE PROBLEM
There are parameters that contributes traffic flows which headway and vehicle average travel speed are among - the determination and proper management of headway and average travel speed is hereby important as the improper management of road traffic flow cause lots of hindrance in transportation and also affects the populace in their day- in- day-out activities.
When the number of traffic is dense, there tends to be a traffic jam which can definitely maximize the time spent by the motorist or other road users to get to their various destination. As the number of vehicle tends to rise at a particular point on a road channel, it brings about the flow density being extremely large and this may affect the normal spacing (headway) in between the vehicles that are present on that road channel. The speed of vehicle is also affected by high volume of vehicles present at a point on a given road E.g. post office to Kwara State- Polytechnic permanent site as the driver can only make use of the space available for them.
1.2     AIM OF THE PROJECT
The aim of this project is to determine the headway and average travel speed of vehicle on the Post office-Kwara State Polytechnic permanent site car park  road.
