Study Behaviour of Passengers on Transit Operation

Nowadays, delays problem are important issue in preparing schedule for public transportation. It is related to behaviour of passengers, behaviour of transportation means and interaction with traffic. Behaviour of passengers are including: demand patterns of passengers, fare payment and waiting time in station and in-vehicle. Behaviour of transportation means included fleet size and frequency of operation. The most interaction between public transportation and others traffic is in traffic congestion. In this paper, we studies different behaviour of passengers duration operation time in two points: in-station and in-vehicle. They are including: arrival rate of passengers, kinds of fare payment and waiting time. For illustrate behaviour of passengers on delays problem we survey they affects in bus operation. Hence, a case study based on an actual public bus operation in Tehran, Iran is used to demonstrate it.

Balancing between Headway and Frequency Scheduling for Bus Service

Bus networks occupy less space in city streets, and compared to other kinds of public transportation, need less investment cost. An accurate bus operation schedule which considers actual arriving and departure time is essential for bus companies, due to high passenger demand. In real-world cases, there are daily differences in the frequency of bus dispatch from the terminal, and headway of buses between each bus bay along their route, depending on peak hour traffic and resulting congestion. In this research we studied effective parameters for preparation of proper bus operation scheduling. Measures are essential to ensure that buses receive priority over other traffic, if they are to be attractive to passengers. Finally, we suggest some solutions for lessening interval time in headway and frequency scheduling for bus services. Data obtained from an actual bus operation in the city of Tehran in Iran was used in this study.

Interaction between Bus Stops Location and Traffic on Bus Operation

In bus networks there are many stations used for boarding and alighting passengers along the bus route. In designing bus stop location three sides approach to be considered; the big picture, street side and curb side. Apiece of three sides have directly affects in the bus scheduling. The effectiveness of bus operation will depend on number of bus stops and its spacing. Basically, bus stations have two kinds: bus stop, use to service passengers in one bus line and bus interchange (terminal) use to share station between some bus lines. This article described a survey on bus stop location efficiency in bus operation where study on bus stop location in three points: near-side, far-side and mid-block were considered. It has been highlighted bus stop location in situation mid-block has higher efficiency than others situations.

Bus Scheduling Model for Adjustment Headway of Bus Carriers

Nowadays, the total volume of passenger trip demand has increased due to population and economic growth. In this situation , government policy encourages people to use public transportation for inter-city trips. In the meantime, buses are the most widely used in transit technology today. The most important issue in buses service is timely arrival. Due to the limited capacity of the streets and increasing car production, we cannot devote a specific lane to bus operation to separate their operation from other traffic. Generally, actual arrival time of buses in comparison to planned arrival time occurs in three scenarios : sooner, on-time, and later. This article represents different scheduling model to achieve timely arrival. For this purpose we tested two different scenarios by actual public bus operation. The data was obtained in the city of Tehran, since Iran was used in this study.
