Chapter 3: LITERATURE REVIEW

We conclude our review paper with an outlook to future research directions. One or both can be used to make it easier for persons who are visually impaired to navigate through the system in order to obtain information about the location of services within Penn Station, such as the ticket counter, information booth, platforms, or specific tracks. Related items that provide additional information but that are not key to understanding the research problem can be included in a list of. The system currently works on a matching principle in which memory patterns represent sound. Congestion pricing, although a more direct demand modifica- tion measure, will not be covered here owing to limited U. Lack of capacity or mobility on adjacent parallel streets.

This typically is done by extension of the green time when a vehicle with signal priority is detected or beginning the green phase earlier in anticipation of the arrival of one of these vehicles. These devices detect vehicle presence through various methods and can use this information to count traffic volumes and estimate spot speeds over the limited detection ranges of these devices. Visual alarms should be used with audible alarms, especially in main concourses and washrooms of terminal buildings. One of the interview questions concerned lessons learned. Break Out of Your Disciplinary Box! This device could be adopted in the transit industry, particularly at information centers in transit terminals. A person without a t-switch-equipped hearing aid may carry a receiver to take in the transit information 1.

One example application of special signal timing plans is in Salt Lake Valley, Utah. Furthermore, since the simplex method is an iterative algebraic procedure for solving linear programming problems-transportation models. The responses include: • Early stakeholder involvement is critical. The information provided on web sites should be in an accessible format or one that can be easily converted to an accessible format 15. State Route 417 is a toll facility that bypasses downtown Orlando, whereas Inter- state 4 runs directly through the downtown area.

When it comes to setting the parking rates, there are two major ways of collecting and implementing these data, as illustrated by parking management programs in Seattle and San Francisco. Adjustable volume telephones are designed primarily for use by persons who are hard of hearing, as well as for those who use hearing aids. Tactile Technologies Tactile Maps Tactile maps consist of a combination of braille and large print that transform printed maps into useful tools for the visually impaired. Conducting Research Literature Reviews: From the Internet to Paper. Assistive Listening Systems These systems provide amplified messages directly to the user's ear.

5. The Literature Review

By using a touch-tone telephone, users can automatically make, confirm, or cancel requests for service. It can also affect the speed of travel on the facility through signal coordination. The transmitter generates a magnetic field that can be picked up by hearing aids that are t-switch equipped. The body of literature includes all studies that address related or identical hypotheses or research problems. Higher parking rates encourage more turnover, allowing more people to park closer to local businesses. The safety part of this study found the following: • The number of crashes and the crash rates declined slightly after removal of the reversible lanes.

Neighborhoods with high parking demand will have their parking rates increased, whereas neighborhoods with smaller demands will have decreased parking rates. The system receives about 5,000 calls per day, or 175 calls per clerk per day. Potential uses for archived and real-time data include: • Real-time data can be used to quickly spot abnormal conditions on the arterial; • Data can be used to calibrate travel demand models; • Archived data and current data can be used to see the effects of signal timing changes or other modifications to arterial traffic operations; • The data provide the ability to calculate travel time on key corridors for disseminating to the general public; • Archived vehicle counts can be reviewed for historical trends to better predict future conditions and develop better timing plans; and • The data can be used in a fully adaptive signal system to control all signals for current conditions rather than using time-of-day plans based on average days. It deals with the problem of how to plan production and in such an industry given several plants at different locations and large number of customers of their products. They are used to prevent people from stepping in the gaps between subway cars and station platforms 13. Independent living centers and programs conducted by persons with disabilities provide the best training 1. For the category of lane-use adjustments, the handbook recommends dynamic lane assignments on freeway frontage roads.

The message is sent by speaking into a microphone connected to a transmitter that sends out a signal. Does it forge a new path? Limited right-of-way or ability to acquire it to construct additional lanes; 4. Portable transmitters usually operate on batteries, whereas the stationary units operate on an electrical power supply. In this connection, a very recent research work of Mahapatra et al. For example, a literature review that focuses on continuing research about the emergence of German economic power after the fall of the Soviet Union.

Roughly how many sources should I include? Telephone Devices Help Phones Help phones can provide orientation and way-finding information by providing passengers with a verbal description of a building's major characteristics or by identifying where facilities are in relation to the passenger's current position 4. Streets with lower use will be cheaper and attract more vehicles. We further remark here that Mahapatra et al. Hearing Aid Compatible Telephones These phones convert sound into magnetic energy when used with a compatible hearing aid and convert that energy back into sound through a flux coil located inside the telephone handset. The constraint structure of the transportation problem is so important that the literature is filled with efforts to provide efficient algorithms for solving it. The related transportation problem is obtained by adding at the most two new constraints to the original problem. The final technology is radio based and is one of the newer methods.

In some installations, the specialized plans can be called up only by time of day or manually by maintenance personnel. Such a system could be used at the customer service counter in a transit terminal and would be of immediate benefit to passengers who are hard of hearing and in need of travel information. This paper shows that in the case of one of the easier 0—1 integer linear problems, namely a single assignment problem, such a relation between linear and 0—1 integer linear formulation can be built. Problem formulation -- which topic or field is being examined and what are its component issues? What types of sources should I review books, journal articles, websites; scholarly versus popular sources? To achieve this goal, the operator of an arterial street must employ the following tactics: • Arterial monitoring, • Speed and signal control, • Geometric configuration, and • Demand modification. A heuristic algorithm for shipping more for less in distribution-related problems is proposed. Also, you can type in a page number and press Enter to go directly to that page in the book.
