An investigation into the use of highway traffic signals at highway-railroad grade crossings
(Texas A&M University, 1997)
Rail-highway grade crossings are amongst the most dangerous of intersections a driver will encounter. One out of every nine accidents at rail-highway crossings produces a fatality. In half of these cases, the crossing is ...
A quantitative evaluation methodology for the sourcing of public sector job functions
(Texas A&M University, 1997)
Public agencies contract out job functions with the objective of utilizing their resources more efficiently. Some major reasons for an organization to contract out services with private sector firms have been, ³to supplement ...
Identification of asphalt binder properties that affect cracking performance of hot mixed asphalt concrete pavements
(Texas A&M University, 1997)
The overall objective of this study was to identify binder properties that affect cracking performance of hot mixed asphalt concrete (HMAC) pavements. In the late 1980s, test pavements were constructed in Texarkana and ...
The evaluation of micro-surfacing mixture design procedures and the effects of material variation on the test responses
(Texas A&M University, 1994)
This study examines statistically the repeatability of the International Slurry Surfacing Association (ISSA) mixture design tests by estimating the h and k consistency statistics for the test results obtained. An idea of ...
Tangent length and sight distance effects on accident rates at horizontal curves on two-lane rural highways
(Texas A&M University, 1993)
This thesis documents an evaluation of the relationships between accident rates at horizontal curves and preceding tangent length and sight distance. Data collection and statistical methods used to evaluate this relationship ...
Effects of the Bus Regulatory Reform Act of 1982 on the Texas intercity bus industry
(Texas A&M University, 1993)
The intercity bus industry in the United States enjoyed its peak profitability and ridership during World War II. Since that time, the private automobile and air service have taken many of the bus industry's revenues and ...
Operation of water supply reservoirs for flood mitigation : hydrologic and institutional considerations
(Texas A&M University, 1996)
Additional demands are being placed upon reservoirs to meet a variety of diverse needs. These demands require efficient management of the limited storage through reservoir operations. This efficiency is most critical with ...
A preliminary evaluation of a speed threshold incident detection algorithm
(Texas A&M University, 1996)
Traffic management centers can reduce emergency vehicle response time to incidents with immediate detection of incidents. Traffic management centers detect incidents by applying speed, occupancy, and/or volume loop detector ...
Transport of entrained air bubbles in fresh concrete due to pressure variations
(Texas A&M University, 1993)
Not available
Prediction of traffic flow for real-time control
(Texas A&M University, 1998)
The prediction of traffic flow on a network and the relationship of these flows to the traffic control signal settings are major factors in the development of an adaptive real-time signal system. PASSER IV is an arterial ...
