Introduction
1.1. Traffic Survey:
Traffic engineers and planners need information about traffic. They need information to design and manage road and traffic system. They use the information for planning and designing traffic facilities, selecting geometric standards, economic analysis and determination of priorities. They use this to justify warrant of traffic control devices such as signs, traffic signals, pavement markings, school and pedestrian

These variations are needed to establish expansion factors for future use. Using expansion factors, AADT can be calculated from short count.
Flow fluctuation on different approaches at a junction or different parts of a road network system.
2.2. Objectives:
The purposes of carrying out traffic volume count are designing, improving traffic system, planning, management etc.
2.2.a. Design purposes:
Structural and geometric design of pavements, bridge, and other highway facilities. Structural design is based on repetition of wheel load on the pavement in entire design life. AADT is needed with traffic growth rate to compute design wheel repetition. Geometric design is based on peak hour volume to avoid congestion.
Intersection design including minimum turning path, channelization, flaring, traffic control devices viz. traffic signs, markings, signals based on approach volume and turning proportions.
Pedestrian volume study is useful for designing side walks, pedestrian crossing etc. 2.2.b. Improvement purposes:
To allocate limited maintenance budget rationally, it is important to know the traffic volume carried by a particular roadway section in order to decide the importance of the road and fixing its relative priority.
In order to improve the roadway operating condition, it is important to know the traffic volume.
To examine the existing operating/service condition of a roadway section.

As a result of an increased population inhabiting one area, traffic congestion is often a major issue resulting from urbanisation. In London, traffic is evidently a problem. As it would be expected from a capital city home to more
Traffic jams are feared and hate by many due to the challenges like wasting time. While traveling from one place to the other one always wishes to reach the destination early enough, but in the case of the traffic jams this usually changes. A person is often late to work, class or any other place a person was wishing to be. In some of the case, people have lost their jobs since they could not make it to work on time due to the traffic jam. It is important to identify that traffic jam in Los Angeles is more of the increase in the number of vehicles (Bento et al. 44). It has been identified that in the days when the fuel prices are low there tends to be a large number of vehicles in town unlike when the prices are high. The increase of the motor vehicles and the jam has led to people engaging into other activities while driving.
Traffic and Hwy Ops provided a recommendation that ICE policy cannot be applied to this project since this is an existing project prior to the Sept. 2013 ICE implementation date. However, unofficially, the traffic volume on SR 29 would require multiple-lane roundabout and introduce concerns for merging and weaving movements. Built year unconstrained vehicle volumes are 8600 for the AM peak hour and 9100 for the PM peak hour. These numbers are based on the all movement which would drive through the intersection.

Austin, Texas has a problem with traffic congestion. The solutions is Mike Heiligenstein and the Central Texas Regional Mobility Authority. The popular city in Texas is constantly growing; consequently the traffic problems are a significant issue. The traffic problems in Texas can be managed, but not eliminated. According to the Central Texas regional Mobility Authority,(CMRMA), a technical solution is the key to managing the difficult traffic congestion. Traffic solutions involve more than the creation of new roads and highways. Mobility Authority strives to create innovative solutions to manage traffic issues in Austin, Texas.
It is important to modify and preserve the transportation system because the number of people using transportation routes is constantly increasing. This means the government must rebuild or replace bridges, pave roads and offer safer more reliable transportation routes that have less traffic and congestion.
At the present moment, the city is in dire need of modifying other means of transportation in order to minimize heavy traffic congestion that we have experienced over the past year. With a new institution of higher learning opening up traffic will get worse once students start enrolling in college come next spring. Therefore, our immediate attention has been focused on addressing this issue so that we can come up with a permanent solution without scapegoating or externalizing the
The number of left turning vehicles per cycle is examined next. If there are less than two left turning vehicles per cycle during the peak hour, then a permissive left turn phase is adequate. It there are more than two left turning vehicles per cycle, the next parameter, speed limit, is assessed. Data collected showed that on average there were three left turning vehicles per cycle during the peak hour. If the speed limit or 85th percentile of the opposing approaching were greater than 45 mph, a protected left turn phase would be warranted. The observed speed limit at the intersection was 35 mph.

As the transportation engineers calculate data for accidents, they also go out and see how adequate the roadways and intersections are for travel to ensure safety while proposing implementation of improvements. First, I would have them look at the different areas and population, what kind of transportation is being used to transport through them (capacity and volume for vehicles to travel through). Also, I
Intersection checks are utilized for timing movement signals, outlining channelization, arranging turn denials, figuring limit, investigating high crash convergences, and assessing clog
density of vehicles is defined as the number of vehicles per unit length. It was mea
For depressed curb inlets at a cross-slope of 2%, the experimental results seem to be greater than the empirical results from both theoretical methods except for curb inlet A. Curb inlets B and D have longer upstream transitional lengths than A which means that they intercept more flows than A. It was observed that more flow is intercepted at a lower road cross-sectional slope
The relationship between people and traffic is down to how people behave on the roads they use and how they deal with the rules associated with this, as well as accepting that others need to use the same space whether this is at the same time or separately. Traffic is viewed in Buchanan's report as an agent
The development of every nation hinges on the effectiveness of their transportation systems. Movement of goods, services and people to and from work is made possible by transportation systems. The importance of effective transportation systems cannot be over-emphasized. A lot of countries are facing Transportation problems and my country Ghana is no exception. A trip of about 30 minutes can take about an hour or more due to traffic jams. This is seriously impacting productivity and has been a topical issue in the country. The situation is the same in Uganda where I currently work. To this end, Transportation Engineers are needed to design roads/ highways that will stand the test of time, plan effective traffic management systems to reduce travel
