Abstract

Interchange stations with their many connecting modes and lines are central for a high-quality public transport system. Bus access at the station needs to operate reliably and efficiently in order to prevent congestion and queues. To this end, a conceptual simulation model for evaluation of bus terminal operations is presented in this paper. It is based on discrete event simulation and able to describe the detailed movements and interactions that occur between vehicles at larger terminals. The model has a modular approach, where common spatial sections at terminals are represented by modules that can be easily combined into many different terminal layouts. An implementation of the model is presented and, as a first sensitivity test, applied in a numerical experiment representing Norrköping interchange station in Sweden. The results indicate that the model can be a useful tool in planning processes.

Highlights

A high-quality public transport system is becoming increasingly important for cities all over the world hoping to reduce the pollution and congestion caused by car traffic
An important factor for a reliable and punctual service that facilitates fast transfers is the capacity of the bus terminal, here defined as an area separated from other motorized traffic modes that has two or more bus stops. e capacity is the amount of vehicles that can use the terminal without causing excessive congestion and queues
We propose a discrete event simulation model for terminal capacity analysis

Summary

Introduction

A high-quality public transport system is becoming increasingly important for cities all over the world hoping to reduce the pollution and congestion caused by car traffic. All parts of such a system need to be well-functioning, and, in particular, its transfer nodes and interchange stations need to have a reliable and efficient operation without introducing unnecessary delays into the system. Ese nodes and stations have a high impact on the system as a whole since they connect the various lines and modes of the system, facilitate transfers and make it possible to achieve a high degree of connectivity within a city or a region While this is important, it is a vulnerability. There are typically train platforms, waiting areas, and commercial facilities competing for the limited
