An Investigation of sign regulation and its effect on the urban environment

Ing, Albert January 1968 (has links)
The rapid urbanization of land and the associated growth of the 'city' have created an unprecedented demand for living and work space throughout this country and the world. The problems that are arising from this process should be examined. Sign proliferation is one of the factors contributing towards the overall effect on the character of the city. The main controversies have centred around sign appearance and location based on their presumed ugliness and effect on their surroundings. Private advertising zeal, or misplaced public priorities are often the cause of these physical problems, which lead to public and private conflicts of interest. The basic aim of the thesis is to examine sign regulation in order to determine its effect on the urban environment, as well as analyse the problems of physical appearance, public and private interests and other resulting problems of regulation. The basic assumptions taken for the study are: it is desirable for man to seek and demand an environment which will contribute towards his well-being; the concept of the public interest is both valid and useful; and planning in the form of sign regulation is useful and possible in our society, with some optimum is possible. As a basis for this investigation it is hypothesized that - The aesthetic purpose of sign regulation results in a conflict of public and private interests, that is being resolved by the adoption of diverse municipal sign regulations.- With the assumptions in mind, the investigation comprised a review of the literature, which was most useful for the establishment of techniques and general requirements for an effective environment, as well as information from a questionnaire directed to several cities in Canada which have undertaken sign regulatory measures with the ensuing problems. The hypothesis is examined specifically through the use of sign legislation of several cities and municipalities in British Columbia. The City of Victoria B.C., one of the cities studied, exhibited many of the typical problems encountered when stricter control over signs is attempted. The process of adopting sign regulation, amidst public and private interests, is aptly illustrated by this example. Another City, Ottawa, Ontario, displayed many of the same problems. Here, sign regulation, as one of the ingredients of a beautification scheme, contributed much to the pedestrian atmosphere and urban environment, as well as showing the relation of improved sign regulation to an overall program of environmental improvement. The most significant observation in the study was the variation in contents of sign ordinances. The many types of regulations presently in use, leads to the conclusion that sign regulation today is complex, with many problems still unsolved. Sign control applied by local government presently could be any level that is achieved in light of the ensuing problems within the community. The basic recommendations are that local government and private interests collaborate to achieve the desired objective. Although this joint effort may lead to diverse regulations, the ultimate goal should be controlling the direction of the developing environment. This can be obtained in part by controlling and regulating signs. Local government, through its delegated power to control street furnishings in the public right-of-way should provide the atmosphere and leadership necessary so that private enterprise may from time to time initiate actions for urban improvement. Subject to the limitations placed on the study, the hypothesis is considered valid. / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate

Prohibition in Symbol Communication

Kunsak, Nancy Elizabeth 05 1900 (has links)
Literature in semiotics lacks consideration of the elements in symbols that communicate specific concepts. Prohibition was the concept chosen for study. Potential prohibitors were represented by line configurations superimposed on background symbols. Seven prohibitors coupled with symbol backgrounds to form 49 experimental symbols were studied through a symbol inventory. Prohibitors constituted the independent variable, while dependent variables were verbal responses by 105 college students to the experimental symbols. Two hypotheses were tested: a) Prohibitors differ in effectiveness in communicating prohibition and b) Prohibitors differ in frequency of distortion of symbol meaning. Chi square analyses and comparisons of proportions showed diagonal lines most frequently elicited prohibition responses. A chi square analysis displayed no significant relationship between prohibitors in distortion of symbol meaning.

Improvement of Conspicuity for Trailblazing Signs

Barker, Julie A. 28 April 1998 (has links)
This document represents efforts to design and evaluate a new sign design for emergency route trailblazing in a two-part series. Study 1 was an off-road field experiment conducted to determine the best color combination and letter design for the emergency sign. Based upon Study 1 results, black on coral, black on light blue, and yellow on purple signs were chosen for further testing against a baseline black on orange sign, all with 125-mm, D series letters. Study 2 was an on-road field study of conspicuity, conducted using an instrumented vehicle through a construction zone-related detour, and a survey questionnaire. The findings indicated that use of a color combination other than traditional black on orange will improve driver performance and safety when used for trailblazing during critical incidents. Based on the conclusions and other anecdotal evidence, the following recommendations were made: 1) Do not use black on orange signs for trailblazing around a critical incident if an existing detour/construction zone is in place; 2) Do not use a black on coral sign for trailblazing around a critical incident; 3) A light blue on black sign is recommended due to generally favorable subjective ratings and for minimization of turn errors in an overlapping detour; however, the black on light blue sign may resemble regulatory signs when headlights reflect onto it; and 4) If reject black on light blue signs based on (3), consider using yellow on purple signs, which resulted in fewer turn errors than black on orange and received generally favorable ratings. / Master of Science

An Experiment with Art Library Users, Signs, and Wayfinding.

Abigail R. Carr 2006 April 1900 (has links)
This paper discusses the effects of stack end signage on user wayfinding success in searches in academic libraries. Site visits to the Chapel Hill Public Library and the Cameron Village Branch Library provided models for test signage for the study, as did the available literature on wayfinding and effective library signage. A three week study was conducted to survey the effects of three different iterations of signage on the success of subjects performing test searches—the subjects used the UNC Chapel Hill online catalog and the posted signage to locate materials in the Sloane Art Library. The results of the study were evaluated qualitatively and suggestions were made for further study and suggestions for elements of effective academic library signage were made.

Development and Evaluation of Food Safety Signs

O'Connor, Sandra 15 September 2009 (has links)
Food borne disease continues to be a significant public health concern. The increasing awareness of food borne illness intensifies the need for proper food safety education among food handlers. The objectives of this study were to develop bilingual (English/Spanish) food safety signs, to determine their comprehensibility and most effective delivery mechanism for presentation to food handlers. The food safety concepts developed into images were: cross-contamination, proper use of thermometer to check temperatures of foods, proper cooling of foods, and do not work with food if ill. The four food safety concepts were designed into three different formats: pictures and words (English/Spanish), pictures only, and lenticular (images that shift when viewed from different angles). The food safety signs were evaluated using forty-five individuals working in the food retail industry. The participants were divided into two groups according to native language (English/ Spanish). For comprehensibility of the food safety signs, 69% responses were noted as correct. The ranking of comprehensibility of the signs was: cross-contamination (93%), thermometer (84%), cooling (64%) and not working if ill (33%). A gap in the understanding of the two lowest scoring food safety concepts (cooling and ill) calls for food safety educational programs and materials that emphasize these concepts. Correct responses for sign presentation were as follows: pictures and words with (80%), pictures only (65%) and lenticular (62%). Comparison of three different formats indicated pictures with words as the most effective presentation. The results obtained can be used as the basics for designing effective food signage for food handlers. / Master of Science in Life Sciences

Traffic and Road Sign Recognition

Fleyeh, Hasan January 2008 (has links)
This thesis presents a system to recognise and classify road and traffic signs for the purpose of developing an inventory of them which could assist the highway engineers’ tasks of updating and maintaining them. It uses images taken by a camera from a moving vehicle. The system is based on three major stages: colour segmentation, recognition, and classification. Four colour segmentation algorithms are developed and tested. They are a shadow and highlight invariant, a dynamic threshold, a modification of de la Escalera’s algorithm and a Fuzzy colour segmentation algorithm. All algorithms are tested using hundreds of images and the shadow-highlight invariant algorithm is eventually chosen as the best performer. This is because it is immune to shadows and highlights. It is also robust as it was tested in different lighting conditions, weather conditions, and times of the day. Approximately 97% successful segmentation rate was achieved using this algorithm.Recognition of traffic signs is carried out using a fuzzy shape recogniser. Based on four shape measures - the rectangularity, triangularity, ellipticity, and octagonality, fuzzy rules were developed to determine the shape of the sign. Among these shape measures octangonality has been introduced in this research. The final decision of the recogniser is based on the combination of both the colour and shape of the sign. The recogniser was tested in a variety of testing conditions giving an overall performance of approximately 88%.Classification was undertaken using a Support Vector Machine (SVM) classifier. The classification is carried out in two stages: rim’s shape classification followed by the classification of interior of the sign. The classifier was trained and tested using binary images in addition to five different types of moments which are Geometric moments, Zernike moments, Legendre moments, Orthogonal Fourier-Mellin Moments, and Binary Haar features. The performance of the SVM was tested using different features, kernels, SVM types, SVM parameters, and moment’s orders. The average classification rate achieved is about 97%. Binary images show the best testing results followed by Legendre moments. Linear kernel gives the best testing results followed by RBF. C-SVM shows very good performance, but ?-SVM gives better results in some case.
