Home-interview survey is one of the most reliable types of surveys for the collection of origin and destination data. The survey is essentially intended to yield data on the travel pattern of the residents of the household and the general characteristics of the household influencing trip making. The information on the travel pattern includes a number of trips made, their origin and destination, the purpose of the trip, travel mode, time of departure from origin and time of arrival at destination and so on. The information on household characteristics includes the type of dwelling unit, number of residents, age, sex, race, vehicle ownership, number of drivers, family income and so on. Based on these data it is possible to relate the amount of travel to household and zonal characteristics and develop equations for trip generation rates.
The rapid growth and sprawl of urban area have generated a substantial increase in travel requirements which resulted in traffic-related problems such as:
· Increased journey times,
· Mixing up of local and long-distance traffic,
· Inadequate public transport facilities, and overcrowding
· Inadequate terminal and parking facilities
· Transport bottlenecks
· Land use development ahead of transport infrastructure
· Increasing environmental pollution
· Increasing road fatalities and injuries
In order to develop a comprehensive transportation plan for the entire region to overcome the deficiencies and to propose additional infrastructure facilities, RSM estimates the present-day travel patterns and predict them for targeted planning years.
The fundamental measure for establishing the travel pattern is through capturing information on trips made by residents of the study area. These surveys by RSM would provide required data to analyze the characteristics of observed travel and yield information on Origins and Destinations by various modes of travel, time of day and the distribution of trips by various purposes. Information about household characteristics, socio-economic condition of the residents is also captured to correlate trip making pattern with socio-economic characteristics and to be able to predict the same for future years. This information is used primarily for the planning of transportation systems and particularly in the location, design, and programming of the new or improved highway, railway, public transit facilities, and services. This survey is being done in on sample basis to be capture and conduct survey in about (1.5% - 2.5%)of households within the study area.
