Effects of Real-Time Passenger Information Systems on Perceptions of Transit Effects of Real-time Passenger Information Systems on Perceptions of Transit Services: Investigations of The Ohio State University Community THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Mahsa Ettefagh, B.S. Graduate Program in Civil Engineering The Ohio State University 2013 Thesis Committee: Dr. Rabi G. Mishalani, Co-advisor Dr. Mark R. McCord, Co-advisor Dr. Gulsah Akar Copyright by Mahsa Ettefagh 2013 Abstract Information systems are increasingly adopted in public transportation to improve service. When well utilized, transit also plays a major role in reducing roadway congestion and mitigating transportation’s negative impacts on the environment, benefits that accrue to transit users and nonusers alike. Nonuser’s recognition of such benefits can be important when agencies seek community support of transit initiatives, and it is possible that state-of-the-art technologies enhance the progressive image of transit. A two-wave survey of The Ohio State University (OSU) community was conducted to study the influence of real-time passenger information systems on travelers’ perceptions of important dimensions associated with transit service. The first wave was conducted before OSU’s Campus Area Bus Service (CABS) implemented a state-of-the- art passenger information system. The second wave was conducted approximately a year after this implementation. Results show statistically significant increases in the value CABS users ascribe to the service provided and their perceptions of personal safety while accessing and using transit services after the implementation of the information system. The results also show statistically significant increases in both users’ and nonusers’ perceptions of the positive contribution CABS makes towards mitigating negative environmental impacts and decreasing congestion. Results further reveal statistically significant association of positive responses with a stated awareness of the ii implemented information system. Socioeconomic variables -- such as gender, whether an individual is a current or past user of other metropolitan transit systems, and university affiliation (student, faculty, and staff) -- are included in the models to control for their possible influences on the community’s perceptions. Interesting statistically significant associations between these socioeconomic variables and positive perceptions are found as well. In summary, the findings indicate the positive effects passenger information systems have on both transit users and nonusers among emerging college-educated professionals, a demographic important for future transit demand and support. iii Dedication This document is dedicated to my family. iv Acknowledgments I would like to express my gratitude to my advisors, Dr. Mark R.

  • Guidelines for the Safe Siting of School Bus Stops
    Guidelines for the safe location of school bus stops 1. How are bus stops determined? Bus stops will be placed on public roadways and will avoid travel on private roads and/or driveways Bus routes are designed with buses traveling on main arterials with students picked up and dropped off at central locations. Visibility – Bus drivers need to have at least 500 feet of visible roadway to the bus stop. If there is not ample visibility (e.g. curve or hill) a “school bus stop ahead sign” is put in place before the stop in accordance with WAC 392-145-030 Bus drivers activate their school bus warning lights 300-100 feet before arriving at the bus stop, where the posted speed limit is 35 mph and under, and 500-300 feet before arriving at the bus stop where the posted speed limit is 35 mph and over. 2. Why are bus stops located at corners? Bus stops may be located at corners or intersections whenever possible. Corner stops are much more visible to drivers than house numbers. Students are generally taught to cross at corners rather than in the middle of the street. Traffic controls, such as stoplights or signs, are located at corners. These tend to slow down motorists at corners, making them more cautious as they approach intersections. The motoring public generally expects school buses to stop at corners rather than individual houses. Impatient motorists are also less likely to pass buses at corners than along a street. Cars passing school buses create the greatest risk to students who are getting on or off the bus.

  • BC Transit. "Design Guidelines for Accessible Bus Stops."
    BC TRANSIT MUNICIPAL SYSTEMS PROGRAM DESIGN GUIDELINES FOR ACCESSIBLE BUS STOPS FORWARD -- MINIMUM REQUIREMENTS FOR DESIGNATION OF ACCESSIBLE BUS STOPS The guidelines for an accessible stop are: In areas where a sidewalk is the pedestrian right-of-way: The preferable roadside condition for a transit stop is a concrete barrier curb 150 mm (6 in) high, without indentation for a catch basin. The transit stop-waiting pad should be a clear minimum of 2.1 m (7 ft) x 1.98 m (6.5 ft). This is necessary in order to accommodate the wheelchair ramp deployment from the bus and to allow for wheelchair movement after clearing the ramp. Provide one or two paved connections from waiting pad to the sidewalk for a width of 1.5 m (5 ft). If street furniture or other such objects are provided (i.e. newspaper box, overhead signage), they must be located to provide a minimum clear width of 1.5 m (5 ft) and clear headroom of 2.0 m (6.5 ft) for the pedestrian path. They must be kept clear of the transit loading and unloading area. If a bench for seating is installed within bus stop areas, it should not be placed on a sidewalk after having a width of less than 2 m (6.5 ft), or within 6 m (20 ft) of any fire hydrant. In areas where no sidewalk exists, a concrete or asphalt pad on the shoulder of the road, as illustrated in Figure 6, is recommended. As illustrated, the pad must be elevated above road grade 150 mm.

  • Child Abduction: Protecting Your Child at School Bus Stops the Best
    Child Abduction: Protecting Your Child at School Bus Stops The best protection for a child at a school bus stop is a vigilant parent. In today's world of dual working parent families, a parent waiting at the bus stop with a child is not always possible. Each year in the United States, between 1.3 and 1.8 million children are reported missing. These children may be kidnapped, lost, or runaways. Some children are taken by a non-custodial parent. Still others disappear with few clues as to the reason. The National Center for Missing and Exploited Children (NCMEC) points out that, in many cases, an abductor is not a stranger to the child. So, while the warning to "stay away from strangers" is good advice, it provides very limited protection. Children are more often abducted or exploited by people who have some type of familiarity with them, but who may not be known to the parents. NCMEC explains that the term "stranger" misleads children into believing that they should only be aware of individuals who have an unusual or slovenly appearance. Instead, it is more appropriate to teach children to watch out for certain situations or actions, rather than certain kinds of individuals. There are generic steps you can take to minimize the chances of your child being abducted. Experts recommend that you teach your child the following: • Her full name, address, including city, state and zip code; phone number, including area code; parents' names, work addresses, and phone numbers. • How to use both a push button and rotary-dial telephone.
