The National Highway Transportation Safety Administration has declared in a recent study that dangerous horizontal curves account for 1/4 of all highway fatalities. TAPCO will present on its Dynamic Curve Warning Systems (DCWS) which is an intelligent system intended to direct traffic around these dangerous curves trough solar LED wireless technology.
Hot mix asphalt (HMA) mix design, in simplest terms, attempts to identify an appropriate aggregate, an appropriate asphalt binder, and the ideal proportions of each for a specific job. Typical parameters in the decision process for aggregate selection include gradation, toughness and abrasion resistance, durability and soundness, shape and texture and cleanliness to some degree. The focus for each of these parameters is performance based. However, what may be neglected at times are other factors that also have an economic or cost impact.
One parameter that impacts the overall cost of HMA is the aggregate's actual asphalt absorption value, particularly with the significant increase in the price of asphalt binder over the past several years. Our testing and subsequent calculations show the dramatic impact that a less than 2% deviation in absorption can have on a HMA section of roadway and the necessity to factor absorption into aggregate selection to ensure the most economical design that meets the job requirements.
This presentation will include an overview of the FHWA sustainability activities and INVEST, FHWA's self-evaluation tool, focusing on pilot test activities.

Reliability-based design (RBD) has the same general format as the familiar limit state design. Limit state design determines a factor of safety, which is the resistance divided by the load. RBD differs in that the resistances and loads are considered to be uncertain quantities, with means and coefficients of variation (COV). The means represent the engineer's best judgment and the COV represents the uncertainty about the mean. Typical values of COV encountered in geotechnical practice are described. The design of a spread foundation on clay is used as an illustration.
The Practical Design Workshop (PDW) design process adds another tool to the designer's toolbox for reducing project costs without compromising safety or the purpose and need of the project. This presentation will demonstrate how the "practical design" philosophy and value methodology were employed for a complex interchange project in St. Louis, MO that saved MODOT over $13 million.

The Ohio-Kentucky-Indiana Regional Council of Governments (OKI) has recently completed a multi-modal regional Freight Plan - the first of its kind in the state. The document recommends projects and strategies to address roadway, rail, runway, and river deficiencies over the next 30 years. While mobility and connectivity are key metrics, economic development is at the heart of the plan - moving OKI forward as a freight leader.
Ohio Lake Erie ports and Ohio River terminals are some of Ohio's most valuable and underutilized transportation assets for shipping commodities to global markets. Each state has been challenged to double exports in the next five years, and efficient use of Ohio's multi-modal transportation system, including key water ports, is essential for Ohio business to reach the global market place. The ODOT Office of Maritime & Freight Mobility, working in conjunction with the ODOT Office of Technical Services and the ODNR Coastal Management Office collaborated to create an online Ohio Maritime Assets catalog for use in a variety of applications which will include freight routing planning, infrastructure and economic development.
Prior to and during time that shale wells are being drilled, heavy trucks carrying drilling equipment and tankers carrying water to and from the site use state highways and township roads. Heavy trucks break pavements and cause potholes and other damage, especially along the edges of rural roadways. Proper planning of well site placement and a thorough consideration of all possible transportation modes, including water and rail, will minimize long-term effects and address traffic congestion, road damage, and potential road dust from the Marcellus Shale exploration.
The current Innerbelt Bridge carrying I-90 through the industrial flats in downtown Cleveland has exceeded its expected design life and is being replaced with two new structures, each carrying five lanes of traffic. The subsurface is predominately interbedded silts and sands with shale bedrock at an average depth of 167 feet. Through an iterative design process, the design build team for the westbound bridge selected a new HP section, HP 18x204 Grade 60, driven to bedrock as the most efficient foundation. The challenges of the new section being used in the design-build environment will be discussed.
Stabilizing subgrade soil with cement or lime has improved the constructability of roadways and reduced costs for undercutting unstable subgrade soils. However, when the subgrade soil contains significant amounts of sulfate, the addition of cement or lime can result in expansion and heaving problems. While it was known that sulfate bearing soils were a concern in Texas and parts of Colorado and Oklahoma, it was thought that sulfate bearing soils were not a concern in Ohio. Recent problems on several projects in Northeast Ohio indicate that sulfate bearing soils in parts of Ohio are a concern. This presentation will discuss the process that causes sulfate heaving, recent events related to cement stabilization of sulfate bearing soils, and steps ODOT is taking to prevent future problems.
The I-71/SR 665 Interchange replacement is the culmination of 10 years of team building, financial planning and phased implementation. This session will discuss how local funding and investments were leveraged with state and MPO funds to pay for and complete one of Ohio's first "Fast TRAC" projects.
In 2006, Horry County citizens passed a capital options sales tax for transportation improvements. It generated $425 million over 7 years and delivered 100 miles of paved roadways. The session will discuss project prioritization and delivery.
A typical workplace includes up to four different generations of employees: Traditionalists; Baby Boomers; Generation X; and Generation Y. It is important to be able to communicate effectively, and work productively, with co-workers and customers from other generations. This session reviews the trends and events that have tended to influence each generation, and provides insights into the different work habits/values and motivational factors that may be encountered. Current and future transportation professionals can gain helpful information for improving their inter-generational communication skills.
Automatic passenger count and manually collected ground truth data have been used to conduct several studies related to bus passenger boarding-to-alighting flow estimation: comparative validation of estimation methods, determination of time-of-day periods of homogeneous flow patterns, grouping of stops to reduce problem dimensionality, and biased estimations by trip length. Empirical results are presented.
To overcome the limitations of visual inspection, a variety of sensors are coming into use. The advantages and limitations of sensors that have been used to monitor the health of bridges in Ohio are discussed. In addition to conventional sensors, such as strain gages, LVDTs and accelerometers, the authors have experience with ground penetrating radar, ultrasound, acoustic emission, and magnetic flux.
To provide safe and efficient signal control, an easy-to-use and reliable method to collect turning movement and vehicle delay data at an intersection has been developed. The method uses a smartphone and multi-touch technology for movement identification and object tracking. Preliminary tests have demonstrated the feasibility of the method for potential future applications.
This presentation introduces the results of a study that explores a method for modeling the impact of traffic flow operations on estimates of vehicle emission factors under various traffic conditions by using the dual-loop data.
Vehicle use is a key component in transportation plans, forecasting emissions and has important links to energy policies. Data from the latest National Household Travel Survey (NHTS, 2009) are used to develop models to estimate the vehicle miles traveled in multi-vehicle households. The results reveal different usage levels for different vehicles and interesting substitution patterns for cars, SUVs, vans and hybrid vehicles.
Ways to include a bridge's contextual surroundings will be discussed through the use of several examples from around the world. This presentation is an update to the one given in 2009 at TRB Bridge Aesthetics Workshop.
Two crossings, Spring Street and Long Street, are included in the first phase of the projects, the I-71/I-670 Interchange. Plans for these bridges will create a more interesting and inviting space over Interstate 71. The Long Street bridge includes a cap over the freeway along the south side of the street. This structural cap is planned as a large public space that can support a future building.
The Franklin County Engineer has an approach to engage the public early in a project to identify situations and locations that may be worthy of aesthetic creativity in the structure type selection. The selected structure type, a three-span, cast-in-place, post-tensioned, haunched box girder posed many challenges to both the designer and the contractor.
Replacement of the Milton-Madison Bridge (U.S. 421) over the Ohio River is currently underway by INDOT and KYTC using the Design-Build process. The project's combination of innovative environmental, design, contracting and construction methods is making it possible to replace the bridge years ahead of schedule, with a 15% cost savings and significantly less disruption than originally expected.
The Milton-Madison Bridge over the Ohio River provides the only crossing of the Ohio River in 74 miles. Instead of a 365 day closure for its replacement, a solution was proposed that cuts the bridge closure to just two five-day durations. The solution involved building the new bridge superstructure next to the existing bridge and sliding it laterally into place, a technique that has never been used for a bridge this large.
The presentation will cover everything you ever wanted to know about Adaptive Traffic Signal Systems.
Discussion of the advantages of using geotextile fabric as a separation layer in an unbound concrete overlay system.
The subject of preservation has grown in interest as pavement owners look for ways to adequately maintain their roadways and stretch their paving budgets. Thin HMA overlays, one and a half inches or less, have proven to be a cost effective solution to improve ride quality, reduce surface distresses, increase strength and provide long- lasting service.
Provide a brief overview of climate change, its role in transportation, how NEPA documentation is being challenged on this issue, and how climate change can be effectively addressed in the NEPA document without expending inordinate resources.
The goal of this presentation is to outline common definitions of livability and to discuss the correlation between livability, transportation, funding and economic growth.
Case studies discuss how Greenroads criteria can be effectively applied to planning, design and construction practices.
Sometimes it is not cost-effective to maintain ramp traffic during reconstruction of interchange ramps, especially ramps located on bridges. Often these ramps are closed and the ramp traffic is detoured to local streets and roads. These speakers will discuss an innovative approach to detouring traffic on the interested use for the first time in Ohio on the I-75 project in downtown Dayton, Ohio.
