The present study is undertaken to fulfill the following objectives –
(i) To collect data for the calculation of time headway of different vehicles on six lane urban roads under mixed traffic condition.
(ii) Use actual field data collected from the traffic monitoring sites on the six lane urban roads to determine free-flow speed (FFS).
(iii) To establish a relationship between the headway and free flow speed for six-lane urban road under mix traffic condition.
The traffic condition on Indian roads is heterogeneous in nature. It consists of fast vehicles as cars, other motorized vehicles and slow vehicles as bicycles. These vehicles widely differ in their physical, size, motive power, control and guidance system as well as performance capability. The difference in static and dynamic characteristics of different value affects the traffic flow.
The Indian traffic characteristics are fundamentally different from those in developed countries, due to mixed traffic flow. This complex traffic scenario, prevailing particularly on urban roads in developing countries, poses a serious challenge to traffic planners and engineers who are on the lookout for suitable solutions. Solutions to the traffic problem can be found through systematic study of all the relevant characteristics of mixed traffic, using appropriate models that will replicate the traffic flow in the field. The main hypothesis behind the project is to assess the relation between headway and free flow speed based on the actual data under mixed traffic flow condition.
On most of the urban roads in India, the traffic consists of an unsegregated flow of different types of vehicles. The traffic in most developing countries such as India is heterogeneous, comprising vehicl...

...ing those in downtown areas. Arterial roads essentially serve longer through trips; also provides access to abutting commercial and residential land uses. Collector streets provide both land access and traffic circulation within commercial, residential and industrial areas. Urban roads are ranked between local streets and multilane suburban and rural highways in street transportation facilities. Downtown streets are signalized facilities that frequently functions like arterials during peak traffic hours. The difference is determined basically by street function, control conditions, and the character and intensity of roadside development. Multilane suburban and rural highways differ from urban roads in the following ways: roadside development is not as intense, density of traffic access points is not as high, and signalized intersections are more than 3.0 Km apart.
The faster the wheels spin, the faster the car will go. Our project requires our car to go at least 3 meters. Our initial trials were successful because our car went 7,8, and then 9 meters. The car went 7 meters in 8 seconds with a speed of 0.875 m/s. It went 8 meters in 10 seconds with a speed of 0.8 m/s. It finally went 9 meters in 12 seconds with a speed of 0.75 m/s. It is what makes the wheel spin instead of just sliding on the ground.
The behavioral models of the traffic as a system has been developed and studied for several decades and the core behavioral models, Gipps’ car-following/acceleration model and lane-changing model are more or less enough to predict behavioral outcomes of vehicles in homogeneous traffic conditions with lane discipline. In mixed traffic conditions with weak/no lane discipline however, the behavior of a vehicle cannot be defined separately using the car-following and lane-changing models. The behavior of a vehicle under such conditions is very dynamic – depending on the behavior of other vehicles in its vicinity. Also, there exists a continuous interaction among the vehicles and therefore, every vehicle is influenced by its surrounding vehicles.
To study how a speeding car (speeder) can be caught by a patrol car, “Catch the Speeder Experiment” was done. Data showed that the speeder car has a constant velocity while the patrol’s car is continually increasing, which means that the patrol car’s is constantly accelerating with time. The position vs. time graph was analyzed to find out when the speeder could be caught by patrol car. It was found that the speeder with a constant velocity could be caught by a patrol car with a constant acceleration.
The fast population growth rate of humans means that the necessity for transportation vehicles is also enormously increasing. Studies have shown that in 1999 the worldwide number of vehicles registered was 700 million. From this huge number of vehicles, the US has a
“Error is part of the human condition”. While errors by road users trigger crashes, the environment in which these take place should no be ignored - - road layout – indirect influences – nature of the vehicle – traffic laws, enforcement or ack thereof (Hijar)

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 crossings. The also use this information to study the effectiveness of introduced schemes, diagnosing given situations and finding appropriate solutions, forecasting the effects of projected strategies, calibrating and validating traffic models.
Traffic jam is one of the most serious problems of urbanization, almost all the modern cities are facing different levels of traffic jam problems. In general, people can ease the traffic jam and not compromise the quality of life by a policy of sustainable development in two aspects including formulating a more efficient transport pattern and changing the urban construction.
Traffic control establishes a set of rules and regulations that people rely on to help avoid collisions and other hazards. With almost 160 million motorists and 3.8 million miles of public roads in the United States, traffic control on the highways is an important aspect of daily life. Without the control of speed there would be more fatalities than we already have now. Speed limits should be obeyed. A motorist going too slow could cause an accident. When everyone is traveling at the speed limit, a car comes up going 40 mph; if you break everyone will, too, perhaps causing a collision. Motorists depend on traffic control to avoid collisions and travel safely to their destination.
We all use vehicles for transportation. People usually go to their desired destination either by driving their own cars or traveling in public transportation. Actually, it might be tough to choose that which one is the best selection for people to travel. Many people choose one of them according to their comfort while traveling and both of them have advantages and disadvantages in different conditions. Public transportation and driving own car both shares differences and similarities in many aspects, such as facility, cost, and comfort as well as traffic jam and accident occurrence.
The primary point of traffic laws is safety, but also keeping order. Following traffic laws is one of the most essential aspects of driving and can increase your safety as well as of the people around you. Knowing the traffic rules in our region and applying them can prevent us from getting involved in an car accident and save us the pain and costs of a traffic ticket due to a violation. If we didn’t have any traffic laws there would be chaos on the roads and many disasters could happen.
Most of cities that people live are sequentially growing, daily routine of many people are also adapted for surrounding in the present. A lot of people have to spend most of their time with travelling though long distances to get from one place to another for connecting their businesses or other purposes by transportation. Most people use public transportation such as BTS and MRT to go each places while many people are using their own cars to travel. Thereby, both transportations have the same destination that is taking and moving people. People can choose vehicles from alter reasons depend on how people are responded to their needs by public transportation and private car that are different in convenience of travelling, expenditure of money and security of travel.
The development of urban transportation has not changed with the cities; cities have changed with transportation. This chapter offers an insight into the Past and the future of Urban transportation and is split up into a number of different sections. It includes a timeline of the different forms of transport innovations, starting from the earliest stages of urban transport, dating back to the omnibus (the first type of urban transportation) and working in a chronological order until eventually reaching the automobile. However, these changes in Urban transport did not happen for no reason. Different factors within society meant urban transport needed to evolve; points will be made on why society needed this evolution. In contrast I will observe the problems urban transport has caused in society as a result of its rapid progression. Taking account of both arguments for the evolution of urban transport, I will look at where it will go in the future.
Traffic congestion, is one of the major problems faced in the capitals and major cities in most countries. As with the increase in the growth rate, comes the growing demand for the use of transportation. This works with the response to the needs of the community.
