Statistical and numerical analyses of pressuremeter tests in glacial tills

This study is performed on pressuremeter tests (PMT) in glacial tills based on comprehensive geotechnical investigation programs for a light rail transit project in the City of Toronto. The main objectives are to establish a correlation between SPT-N values and PMT parameters, and the Menard “α” factors for glacial tills. Currently, there are no such relationships available. So first, the pairs of PMT data and SPT-N values are collected at the same depth and test area. With these paired data, two linear correlation equations are established. Then, the numerical simulation is performed for PMTs in glacial tills by using finite element software, Plaxis 2D. The Mohr-Coulomb material model is used to model the different types of soil. The Menard “α” factor is suggested based on the best match between numerical prediction and field PMT. Ranges of SPT-N, EPMT and PL are also suggested for glacial tills.

The Relationship ◽

A quantifiable basis for developing design guidelines for pedestrian access to light-rail transit (LRT) stations is provided for planners based on observations in Calgary, Canada. Calgary's LRT system, which began operations in 1981, has been operating for long enough for walking patterns to and from its stations to become established. Interviews were conducted with 1,800 peak-hour LRT users about the origins and destinations of their LRT trips. Those who walked to or from a station were asked to point out on a map their approximate origins or destinations. The distances were then measured off the maps. Walking distance guidelines were developed for central business district (CBD), transfer and local stations. Catchment area maps were produced, and the relationship between reported walking time and measured walking distance was calculated. Also compared are the walking distances at LRT stations and the walking distances at bus stops. The research strongly indicates that people walk farther to reach an LRT station than a bus stop. Using bus walking standards would result in an underestimate of LRT walking distances by about half. For the city of Calgary the average walking distance to suburban stations is 649 m with a 75th-percentile distance of 840 m. At CBD stations the average walking distance is 326 m and the 75th-percentile distance is 419 m.

Edmonton is currently implementing a plan to significantly expand its light rail transit network. Transit expansion is part of a larger plan to encourage transit-oriented development (TOD) around new and existing transit stations and precipitate a shift towards more dense, efficient land use. Transit technology and routes were then selected, in part, based on their perceived ability to facilitate TOD, and the City has also created the TOD Guidelines and created the TOD Manager position to advance their land use goals. This research includes interviews with 6 developers who are currently undertaking large TOD projects to understand their perceptions of TOD as an investment in the Edmonton, and how effectively municipal decisions have facilitated TOD. The TOD Manager was interviewed, as he plays a critical role in facilitating TOD in Edmonton, as was a planner from the City of Edmonton to provide insight into TOD from a planning perspective and the development approvals process.

The Relationship

This study examines the relationship between light rail transit (LRT) stations and changes in neighborhood characteristics associated with gentrification using spatial regression analyses with longitudinal data across 14 US urbanized areas (UAs). Overall, we do not find evidence of prevalent gentrification in LRT station areas. An analysis of UA-specific impacts shows heterogeneous outcomes across different UAs, particularly: strong transit-oriented development (TOD) effects accompanied by gentrification in San Francisco and TOD with countergentrification in Portland. Our results highlight that different local and regional planning efforts can lead to different types of changes in transit station neighborhoods.

Transit Accessibility ◽

Abstract A new transportation system built in Palembang, the South Sumatra Light Rail Transit (otherwise known as LRT Sumsel), stretches along the road corridor from Sultan Mahmud Badarudin II Airport to the Jakabaring Sport City Palembang. In practice, a city needs criteria that must be met to develop a city properly. One of the urban development approaches is Transit-Oriented Development (TOD), an approach that emphasizes not only transit accessibility but also a sustainable environment. Therefore, in developing a city that has mass transportation, TOD calls forth the integration of all transportation modes with the elements of the city. This is closely related to the design of urban space at the transit area and how to achieve the concept of TOD. This research was conducted to find out whether the space around the South Sumatra LRT transit area has properly fulfilled the TOD concept. To achieve the success of Palembang City development, the complexity of TOD and the quality of urban space must be integrated. The goals of this research were to identify the elements of urban space in the transit area. The South Sumatra LRT station is the case study in this research employing descriptive qualitative methods using observation, stakeholder interview, and literature study. The results of the study point out that LRT Sumsel must highlight the availability of parking and attributes, which can allow more frequent transit activities. This research hopes that it can provide consideration for the development of the city of Palembang in terms of architecture and transportation utilization.

Isolated Species

Examination of (35) samples of spices obtained from local markets for the purposes of isolating and diagnosing fungi growing on them. Anine isolates belonging to 13 different types of fungi were diagnosed by the standard dilution method with three replications, and it has been observed that the most samples from which the fungi were isolated is ginger. It was found that the most isolated species of fungi are Penicillium, Aspergillus, and Rizupes spp. A rare colony of fungi was observed, which indicates contamination of the spices under study with the fungus. The present study aims to identify the potential risks of the presence of fungi in spices and what may result from mycotoxins that may be the cause of many chronic diseases as a result of using these spices in large quantities. The study recommends limiting the use of contaminated spices, especially ginger, in preparing food and its uses, in addition to other types such as cloves, black and white pepper, and other types of spices found in the local markets, especially the expired ones.

Community Input

Virtually all public works projects require a substantial planning effort to identify impacts, costs, and alternatives. Federal and state laws and regulations call for certain levels of public involvement during planning, but meaningful, collaborative public involvement entails doing more than the minimum requirements. This is particularly true when there appears to be an imbalance in public input, where one viewpoint is heard above others. The San Diego Metropolitan Transit Development Board (MTDB) has undertaken efforts on two corridor projects to expand its public involvement in ways that maximize the range of community views, enhance project design, and build support for the project. In addition to the traditional public meetings, newsletters, and open houses, MTDB has used public relations firms, neutral facilitators, and staff outreach to achieve expanded public involvement goals. MTDB has found that, while there are risks and costs associated with these approaches, they ultimately result in better projects that receive more widespread public and political acceptance.
