A Software Package For Time-Tabling And Scheduling Of A City Transport System, V B Kaujalgi, A K Rao, T A S Vijayaraghavan Jun 1989

A Software Package For Time-Tabling And Scheduling Of A City Transport System, V B Kaujalgi, A K Rao, T A S Vijayaraghavan

IIMB Management Review

The planning control and implementation of an urban transportation
system is a complicated decision process. In practice, due to its complexities,
the problem has to be divided into sub problems considering only certain
aspects of such a system. Hence the focus of the present paper is on the
vehicle time-tabling and scheduling aspects of a city transportation system. A
computer software package for an urban road transport manager in his
day-to-day operations is developed. It can also be used for planning purposes.
The transport sector in any city is generally managed by public sector
organizations. Such systems are very complex. …


Accidents Involving Vehicles Parked On Shoulders Of Limited Access Highways, Kenneth R. Agent, Jerry G. Pigman Jun 1989

Accidents Involving Vehicles Parked On Shoulders Of Limited Access Highways, Kenneth R. Agent, Jerry G. Pigman

Kentucky Transportation Center Research Report

This study was conducted to quantify the extent of the problem of accidents involving vehicles on shoulders of limited access highways. Accident data for a three-year period (1985-1987) were collected along with a survey of vehicles stopped on the shoulder on interstates and parkways.

While the percentage of all accidents on interstates and parkways involving a vehicle on the shoulder is small (1.8 percent), the percentage of fatal accidents involving a vehicle on the shoulder is significant (11.1 percent). The accident data revealed that the majority of shoulder vehicles had stopped for an emergency stop as opposed to a leisure …


Comparison Of Three Methods Of Pavement Design For Lexington-Fayette County, David L. Allen Jun 1989

Comparison Of Three Methods Of Pavement Design For Lexington-Fayette County, David L. Allen

Kentucky Transportation Center Research Report

It is imperative in an era of limited budgets for construction and maintenance of streets and highways that a rational approach be followed for managing these funds. One of the first steps of this management process is the adequate and proper design of new streets and roads. In the interest of having a more rational system of design, representatives of the Lexington-Fayette Urban County Government requested the Kentucky Transportation Center to assist in the development of a new pavement design system that more clearly reflects differences in soils, traffic streams, environmental conditions, and materials. In fulfillment of that request, this. …

Warrants And Guidelines For Installation Of Guardrail, Jerry G. Pigman, Kenneth R. Agent Jun 1989

Warrants And Guidelines For Installation Of Guardrail, Jerry G. Pigman, Kenneth R. Agent

Kentucky Transportation Center Research Report

Kentucky, as most other states, has in the past relied on the AASHTO "Barrier Guide'' for guidance in the installation of guardrail. Additional information related to barrier selection and installation was recently published in the form of the AASHTO "Roadside Design Guide. " However, considerable judgement is required for application of this information and it was determined that significant benefit could be derived from development of guidelines representative of conditions in Kentucky. Listed below are significant results from this study.

  1. Results from a previous survey of guardrail standards and guidelines were summarized and it was found that only a few …


Stability Of Asphaltic Concrete Mixtures, David L. Allen, Hossien Roghani Jun 1989

Stability Of Asphaltic Concrete Mixtures, David L. Allen, Hossien Roghani

Kentucky Transportation Center Research Report

This study was initiated with the general objective of quantifying some of the parameters that govern the stability and rutting characteristics of asphalt-bound materials. Aggregate type and gradation, loading magnitudes and patterns asphalt types and viscosity, are known to affect the stability of an asphalt mixture.

The study was conducted in three phases. The first phase was a study of the effects of large stone gradations on the rutting and fatigue characteristics of an asphalt base mixture. The second phase was an in-depth study of the mastic portion (smaller than 3/8-inch) of an asphalt mixture. The third phase was a …

Bond And Fatigue Characteristics Of High-Strength Cement-Based Composites, Somboon Chimaphant May 1989

Bond And Fatigue Characteristics Of High-Strength Cement-Based Composites, Somboon Chimaphant

Dissertations

The results of a series of tests on a variety of high strength cementitious composites yield a model from which an empirical equation of general normalized pull-out stress vs. pull-out displacement relationship is developed. A new variable named the "Brittleness Index" is defined and used in the proposed equation. Additionally, the concept of maximum strain is used to predict the fatigue life of high strength concrete.

Three sizes of deformed bars and two types of steel fibers with four different volume fractions were used to observe bond-slip and pull-out characteristics of high strength concrete. The results indicate that the maximum …


Anaerobic Biodegradation Of Trichloroethylene With The Addition Of Sugar Using Activated Carbon-Fluidized Beds, Suxan Huang May 1989

Anaerobic Biodegradation Of Trichloroethylene With The Addition Of Sugar Using Activated Carbon-Fluidized Beds, Suxan Huang

Dissertations

Anaerobic biodegradation of trichloroethylene (TCE) was carried out in a two-stage granular activated carbon fluidized bed bioreactor. The intermediate products were identified as: dichloroethylene (DCE), vinyl chloride (VC), 1,2-dichloroethane (DCA) and chloroethane (CA). Of the three geometric isomers of DCE, the trans-1,2 dichloroethylene (TDCE) was found to be the most predominant species, The production of DCA suggested a diverted reaction sequence from the conventional sequential reductive dechlorination pathway postulated in the past literature. CA was believed to be a product of VC and/or DCA. The co-substrate glucose was implicated for this reaction specificity. Based on our data and on other's …


Air Stripping Of Volatile Organic Contaminants Using Rotating Disc Contactor, Kai-Ping Hsueh May 1989

Air Stripping Of Volatile Organic Contaminants Using Rotating Disc Contactor, Kai-Ping Hsueh

Dissertations

Previous studies have suggested that the transfer of VOCs to the atmosphere by air stripping may be a convenient and potentially cost-effective method to remove these compounds from the water. A Rotating Disk Contactor (RDC), similarly to other aeration devices, can provide intimate contact between the VOC-bearing water and air. It is believed that under carefully selected operating conditions, the RDC system are more competitive with packed tower than other aeration methods. The objectives of this study were to evaluate the feasibility of using the RDC to strip VOCs from the contaminated water and to develop a mathematical model to …


Permeability And Volume Change Characeristics Of Bentonite-Sand Mixes In A Contaminant Environment, Yuan-Hsun Wu May 1989

Permeability And Volume Change Characeristics Of Bentonite-Sand Mixes In A Contaminant Environment, Yuan-Hsun Wu

Dissertations

This research was conducted to study the characteristics of permeability and volume change of bentonite-sand mixes due to contaminants. The soil specimens consisted of clean sand, bentonite, and fly ash. Test liquids included seven diluted organic and inorganic chemicals and a landfill leachate.

Index tests included liquid limit, expansion, cracking, and sedimentation tests. Expansion tests proved to be the most useful for permeability evaluation in a contaminant environment.

The conventional consolidometer permeameter and flexible wall permeameter proved to be not completely satisfactory for testing soft bentonite mixes. A triple ring permeameter was developed to compensate for the limitations of these …
