Developing a web-based advisory expert system for implementing traffic calming strategies

Lack of traffic safety has become a serious issue in residential areas. In this paper, a web-based advisory expert system for the purpose of applying traffic calming strategies on residential streets is described because there currently lacks a structured framework for the implementation of such strategies. Developing an expert system can assist and advise engineers for dealing with traffic safety problems. This expert system is developed to fill the gap between the traffic safety experts and people who seek to employ traffic calming strategies including decision makers, engineers, and students. In order to build the expert system, examining sources related to traffic calming studies as well as interviewing with domain experts have been carried out. The system includes above 150 rules and 200 images for different types of measures. The system has three main functions including classifying traffic calming measures, prioritizing traffic calming strategies, and presenting solutions for different traffic safety problems. Verifying, validating processes, and comparing the system with similar works have shown that the system is consistent and acceptable for practical uses. Finally, some recommendations for improving the system are presented.

Engineering characterisation of epoxidized natural rubber-modified hot-mix asphalt

Road distress results in high maintenance costs. However, increased understandings of asphalt behaviour and properties coupled with technological developments have allowed paving technologists to examine the benefits of introducing additives and modifiers. As a result, polymers have become extremely popular as modifiers to improve the performance of the asphalt mix. This study investigates the performance characteristics of epoxidized natural rubber (ENR)-modified hot-mix asphalt. Tests were conducted using ENR–asphalt mixes prepared using the wet process. Mechanical testing on the ENR–asphalt mixes showed that the resilient modulus of the mixes was greatly affected by testing temperature and frequency. On the other hand, although rutting performance decreased at high temperatures because of the increased elasticity of the ENR–asphalt mixes, fatigue performance improved at intermediate temperatures as compared to the base mix. However, durability tests indicated that the ENR–asphalt mixes were slightly susceptible to the presence of moisture. In conclusion, the performance of asphalt pavement can be enhanced by incorporating ENR as a modifier to counter major road distress.

Web-Based Expert System for Optimizing of Traffic Road in Developing Countries

In current times, the increase of road users using road traffic include street carriers, vehicles, pedestrians, buses and other forms of transportation, both individually or in combination, utilizing the universal means to travel. Vehicle regulation and laws governing traffic are traffic laws, whereas road rules are natural regulation and standards that might be advanced in time in facilitating the traffic flow to be methodical and well-timed in emerging countries. Experts of the traffic road system [TRSys] suggests a procedure for road traffic experts and offers supervision and ice advertising on selecting effective and suitable policies. The road traffic development in dealing with traffic-associated complications needs various wide-ranging knowledge and information achievable from road traffic sources for example written sources [books, manuals, technical reports and standards] and traffic expert opinions. A computer tool is utilized in developing the expert system is Web-based expert system Microsoft [PHP]. It is a dominant application containing all the essential services to construct a Windows or Web-based applications for instance expert systems quick and proficient tools. TRSys is an online consultant system in traffic safety to implement a road network in developing countries that can help engineers, consultants, contractors, civil engineering students, and decision makers. The usefulness of the expert system [TRSys] to give recommendations which are appropriate to Road Network for Developing Countries. Traffic Road System [TRSys] is an innovative system advanced in this research to aid junior engineers. It also helps decision-makers and students in identifying traffic complications in developing countries and consequently recommend the application of suitable solutions.

Pemodelan Kesediaan Masyarakat Beranjak Kepada Pengangkutan Aktif

Active transport is vital to ensure urban living in a clean, healthy and quality environment. Today, rapid motorisation in Malaysia has been associated with congestion and accidents. Besides, carbon gas emission is polluted the environment and grossly affect people’s quality of life. This study is aimed to predict the variable that effect shift to active transport for short trips. The study employed a survey method, where a set of questionnaire was distributed to 400 samples involved population of five sub-districts in Kota Bharu, which is within 12 km radius from the city centre. The data indicated that almost 100% of the respondents and their households use motorised for daily activities. In addition, 52% of respondents agreed to switch to active transport and 48% the rest did not agree. Willingness to shift to active transport based on state preference survey is significantly influence by level of education and occupation. A study using logistic regression has shown that the highest level of education and occupation of an increasingly less likely a user is to use active transportation. The findings of this study can help relevant agencies such as transportation planners and urban planners to introduce the use of active transport as a mode of transport in city centre.

Evaluation of permanent deformation and durability of epoxidized natural rubber modified asphalt mix

The road distresses have caused too much in maintenance cost. However, better understandings of the behaviours and properties of asphalt, couples with greater development in technology, have allowed paving technologists to examine the benefits of introducing additives and modifiers. As a result, modifiers such as polymers are the most popular modifiers used to improve the performance of asphalt mix. This study was conducted to investigate the use of epoxidized natural rubber (ENR) to be mixed with asphalt mix. Tests were conducted to investigate the performance characteristics of ENR-asphalt mixes, where the mixes were prepared according to the wet process. Mechanical testing on the ENR-asphalt mixes have demonstrated that the asphalt mix permanent deformation performance at high temperature was found to be improved compared to the base mixes. However, the durability studies have indicated that ENR-asphalt mixes are slightly susceptible with the presence of moisture. The durability of the ENR-asphalt mixes were found to be enhanced in term of permanent deformation at high and intermediate temperatures compared to the base asphalt mixes. As conclusion, asphalt pavement performance can be enhanced by using ENR as modifier to face the major road distresses.
