This research is focused on the development of a model for estimating arterial travel time by utilizing Automatic Vehicle Location (AVL) system-equipped bus as a probe vehicle. As an initial achievement, a prototype arterial travel time estimation model, applied to the bus arrival time estimation, was developed. The methodology adopted in this phase of the travel time estimation model was the o...

We consider a bus stop that is located a short distance upstream of a signalized intersection. A bus that dwells at this so-called " nearside stop " can impede queued cars upstream as they discharge during their green time at the intersection. Added car delays and residual queues can result. All else equal, the closer the stop's location to the intersection, the greater the potential damage to ...

The emphasis of this research effort was on using AVL and APC dynamic data to develop a bus travel time model capable of providing real-time information on bus arrival and departure times to passengers (via traveler information services) and to transit controllers for the application of proactive control strategies. The developed model is comprised of two Kalman filter algorithms for the predic...

Majority of the million plus cities in India are facing serious problems of traffic congestion and pollution due to the unprecedented and rapid pace of urbanization in last decade. City planners are providing solution to these twin problems by developing Mass Rapid Transit System including Metro and BRT in many Indian Metropolitan cities. The availability of transit network and pedestrian acces...

In this paper, data from an on-site survey in Seoul, Korea and the microscopic traffic simulation are used to evaluate the performances of Bus Rapid Transit bus stops operated on different placements to their nearest traffic signals: far-side, and near-side. The influence of Bus Priority Signal Systems is also analyzed. The results reveal that a near-side bus stop performs better under the curr...

In this report, we introduce a vision-based system to monitor for suspicious human activities at a bus stop. The system currently examines behavior for drug dealing activities which is characterized by individuals loitering around the bus stop for a very long time with no intention of using the bus. To accomplish this goal, the system must measure how long individuals loiter around the bus stop...

Enhancing a bus transit system is a possible solution to the growth of congestion in urban areas. Issues related to the safety of bus passengers, either on board or during their travel to a bus stop, should be considered. This article presents a GIS method to identify risky bus stops on a single bus route in the Serdang and Seri Kempangan area according to three attributes: location, characteri...

Effectiveness of the existing local bus stops as transition points in mass transportation system Dhaka metropolitan city area was investigated through a questionnaire survey among 120 randomly selected passengers at four namely, Azimpur, Jhigatola, Collegegate and Motijheel, between March June, 2004. Bus stop found one major factors for common people that influence standard services. Inappropri...

Recently, bus transit operators have begun to adopt technologies that enable bus locations to be tracked from a central location in real-time. Combined with other technologies, such as automated passenger counting and wireless communication, it is now feasible for these operators to execute a variety of real-time strategies for coordinating the movement of buses along their routes. This paper c...
