Daily patterns – The traffic volume generally varies throughout the week.
The peak is reached and dispersed over a longer period than the morning peak. The afternoon peak on the other hand is characterised by a generally wider peak. The peak in the morning is often more sharp by reaching the peak over a short duration and immediately dropping to its lowest point. Peak in the morning followed by a lean flow until another peak in the middle of the afternoon, after which there may be a new peak in the late evening. Hourly patterns – Typical hourly patterns of traffic flow, particularly in urban areas, generally show a number of distinguishable peaks.When analysing the traffic one must also be aware of the directional distribution of traffic and the manner in which its composition varies as it is important to deal with tidal flow. Monthly and yearly Pattern: The season-to-season variation throughout the year.Daily Pattern: The day-to-day variation throughout the week.Hourly pattern: the way traffic flow characteristic varies throughout the day and night.There are three important cyclical variations: In order to predict traffic flow volumes that can be expected on the road network during specific periods, knowledge of the fact is required that traffic volumes changes considerably at each point in time. Different methods of traffic volume count are as mentioned below – The various types and methods used to collect traffic data not only provide a good and valuable coverage of the required traffic information.

Traffic counting falls in two main categories, namely: manual count and automatic count.Traffic data collection forms the integral part of traffic volume study as it provides the raw data and includes primary survey. Traffic Volume Count can be done by various methods depending upon various factors like manpower available, budget, technology/instrument available, magnitude of traffic data required or to be collected which will then determine quality and type of vehicle classification to be adopted. The objectives covered in it includes identifying the hourly distribution of vehicles and peak hour, identify level of service and compare modal composition on different hierarchy of roads. To provide possible solutions and improvement suggestion for the problem identified. The purpose classified traffic volume count is to draw inferences on the basis of data collected.
