The major goal of this paper is to investigate the use of GPS technology in public transit systems with a particular focus on services-on-demand types of transit systems (dial-a-ride, jitney, door-to-door services, taxi, etc.). The paper argues that such services have a greater potential than traditional bus or rail systems for luring SOV drivers out of their automobiles and into public transit, given the opportunities afforded by GPS and advanced communications technology for more efficient scheduling and control for these services. The paper reviews advantages and disadvantages of various forms of public transit and then discusses ways in which GPS technology has advanced automatic vehicle locator (AVL) systems that have already contributed to improved operations of fixed-route bus systems. The paper then reviews available literature on costs of this technology and its impact on overall operating costs.

This thesis introduce a methodology for calculating OD flow of bus stops
based on the data of intelligent card of public transit. First, the date for deducing OD
flow of bus stops and the process of data preparing are expatiated, then analyzing
the characteristics of intelligent card of Beijing public transit, with the data and
characteristics all the possible interchange route-pairs, interchange stops and
interchange directions can be estimated. Identifying number of transfers for each
route-pairs, based on the data of intelligent card. Finally, the methodology of
calculating the OD flow of bus stops of the whole Beijing is introduced.

Using a lateral driver assist system for snowplow operators as an example, the impact on driver performance of subtle changes in control laws was explored. The display for the driver assist system provided integrated information on current lateral position, road orientation and curvature, and a prediction of future location. Changes in driver performance were seen by modifying the gains for terms within the prediction control law. Most notably, removal of the prediction feature or road orientation led to substantially decreased performance. Gain increases above one in the road orientation term led to improved speed, lateral positioning, and steering wheel standard deviation due to the stability improvement of the driver assist system.

Effective travel time prediction is very important to many advanced traveler information and
transportation management systems. In many travel time prediction approaches, the link
travel time accumulated database (DB) and real-time link travel time information are used to
predict the link travel time. Especially, the link travel time accumulated DB, which extracts
the periodic (i.e., daily, weekly, etc.) patterns of link travel time, is believed having direct
influence on the accuracy of travel time prediction in normal traffic status. In this paper, an
automatic updating approach of link travel time accumulated DB is proposed to enclose the
long- and mid-term changes in the road traffic status caused by variations in the road
conditions (changes in road networks, etc.) and socio-economic development (changes in
vehicle ownership rate, etc.), and then improve the accuracy of the DB constantly. By
applying the approach to a probe information system in Nagoya city, it is confirmed that the
advancement of DB is useful to improve the road network coverage of travel time
information, and the accuracy of travel time prediction.
