In order to we need to study new ways to improve urban plan transportation services investment or management decisions harmonize demand for the growing capital of the population.
So, In this paper we are determine the factors affecting the operation of public transport of Ulaanbaatar have been studied and recommendations for further improved network planning
Today, there is an urgent need to create a public transport system by planning, upgrading and improving urban transportation services with urban planning and demographics and increasing the quality and accessibility of public transportation.
So, it is time to research the current situation of urban public transport services and to develop a dynamic growth trend and to develop strategic solutions, implementing measures and network planning models.
It is important to socioeconomic importance of improving network planning based on passenger demand to develop public transport services as the basis for future urban planning in Mongolia.
This study contributes to the research evidence-base within the UB context by addressing the gap in knowledge relating to the pre-travel information-seeking behaviours of everyday public transport users, which takes account of preferred information sources and use of technology for seeking information as well as journey planning stages.
Our research was based on passenger planning theory, system approach, economic analysis, mathematical statistical methods, regression and correlational analysis. Within the theoretical and research work has been carried out in urban traffic management, demand, supply, network and passenger traffic.
1.Public transportation Planning models, their stages and roles.
The traditional approach or «Four stages» is widely used in transportation planning in international practice. Each stage of the «Four stages» methodology has a specific purpose and describes the key roles of each stage:
- First stage. Trip Generation
Total load size of public transportation. Total passenger traffic between Ulaanbaatar and its districts is determined. The main data for this calculation are: the number of people, the number of households in the household, the number of household vehicles, the number of land use units (how many factories, businesses, shops, etc.) and the drivers and drivers of traffic.
- Second stage. Trip Distribution
The direction of distribution of the total traffic curve is calculated from which city to city, district to district.
After the Traffic Analysis Zone (TAZ) is issued, the «Traffic Factor» determines which area of the traffic will be intensified from the zone to which the traffic is intense.
- Third stage. Mode choice
The movement is made by all types of vehicles (by car, by bus, taxi).
Based on the type of transportation of the population in the capital city, the capacity of the public transport vehicle, the interval, the length of the passenger, the rotation time, and the number of buses.
- Fourth stage. Trip assignment
Along the road network, how many movements are created and the traffic load will be allocated to each road and route.
The «Traffic Distribution Modeling» is a computer modeling and allocates traffic to the preceding stages on the road network, and what traffic is the traffic on which traffic is measured, traffic conditions, classification, public transport schedules, prices, traffic alerts, etc. do it.
The design of the public transportation service system will make comparisons of traffic load and general traffic load conditions when planning urban and transport plans. Adjust your modeling at this stage.
