Multimodal Simulation as a Tool for Complex System Evaluations

Speakers: Tim Miller and Chris Beard, Lochmueller Group

Today’s simulation tools are becoming increasingly capable of replicating transportation behaviors beyond the automobile. Chris Beard of Lochmueller Group will present case studies of multimodal simulations developed in support of transportation planning for a major medical campus in St. Louis, Missouri. Examples will include pedestrian and traffic simulations of complex intersections (including a partial continuous flow intersection), pedestrian simulations within the confines of a busy transit station, and simulation of drop-off/pick-up activities within an auto court/porte cochere using multiple vehicle types, including valet, self-park, chair cars, and others. These simulations and their robust output helped facilitate data-driven decision-making by medical planners regarding the future of the rapidly expanding campus.

Reimagine Streets Outside the Boundaries of Functional Classifications

Speakers: Tim Miller and Chris Beard, Lochmueller Group

Traditionally, streets have been characterized by functional classification standards, which generally define the level of mobility and access to adjacent land uses that the street provides. These classification standards are no longer effective at defining a modern network of multi-modal, Complete Streets. Using the recently completed St. Louis Downtown Multi-Modal Transportation Study as an example, this presentation will focus on reimaging streets using a new set of street typologies. These typologies emphasize the overarching purpose and goal of each street relative to a broad array of community objectives (such as modal priorities, economic development, placemaking, etc.) that transcend traditional mobility and access targets. The presentation will discuss how a system of street typologies can be established to serve as guidance for policymakers, stakeholders, planners, and designers alike.


Wednesday, March 11    2:00-2:50, STEW 314

Roundabouts 101 – A Bookends Approach to Public Understanding of Roundabouts

Speakers: Jeff Whitaker and David Goffinet, Lochmueller Group; Joe Wellman, City of Washington, IN; Craig Parks and Michael Maurovich, American Structurepoint, Inc.; Travis Mankin, INDOT

When unique intersection challenges call for innovative design solutions, roundabouts are sure to follow. A carefully planned approach at engaging the public in this conversation can alleviate apprehension for this age-old European intersection option that is gaining traction throughout the State. Join in as consultants, INDOT and local officials share ideas on a creative approaches to public information meetings and community events that have engaged the public throughout the project development and helped bring new understanding to the world of roundabouts. The session will include an informal mock public information meeting followed by a panel discussion from those who have seen the first-hand benefits of engaging and educating the public on roundabouts.


Wednesday, March 11     4:00-4:50, STEW206

Designing Streets for Multiple Users and Different Vehicle Types:  Serving Multiple Cultures Through Design

Speakers: Dominick Romano, Lochmueller Group & Phil Cornelius, Daviess County

Daviess County Road 900E has a mixed use of users, including passenger vehicles, commercial trucks, and horsedrawn buggies. A feasibility study identified the need to accommodate this mix of users by incorporating “buggy lanes,” and the road was reconstructed to include 8-foot shoulders/buggy lanes. Upon completion of the first 1.5 miles of reconstructed roadway, information sessions were held with all users to acquaint them with the proper usage of the buggy lanes.

Constructed Wetlands for Source Water Protection

Speaker                                 Mark Harrison, PE, LEED AP, Lochmueller Group

Agricultural run-off encourages growth of cyanobacteria in freshwater, which contaminates sources for drinking water as was dramatically illustrated when Toledo was forced to order a water ban in August. But operators have struggled to find a cost-effective way to protect source water. In northwestern Ohio, the Grand Lake St. Mary’s State Park has wrestled with this problem at its 13,500-acre lake. About 95% of the land draining into this reservoir is agricultural, carrying with it high concentrations of nitrogen, phosphorus, and pesticides. In 2009 and 2010, the lake experience outbreaks of cyanobacteria.

The Ohio EPA teamed up with local officials to restore the lake via a pilot project that attempted to buffer the watershed from the flow of agricultural runoff. They organized a demonstration project, funded in part by a federal grant, which employs a series of five treatment processes based on BMPs for source water protection. Lochmueller Group’s responsibility involved design of the secondary treatment stage that uses constructed wetlands to uptake phosphorous and nitrogen. In this presentation, we’ll explore how adaptable this technology is to address operators’ concerns about source water protection.

Speaker Bio

Judge Me By My Size, Do You? Yoda Teaches All We Really Need to Know About Water Treatment

Speaker                                                 Chuck Gray, City of Mt. Vernon Water Superintendent

Co-Authors                                           Catherine Pallotta, Senior Project Engineer at Lochmueller Group

The great Jedi Master Yoda, from the Star Wars movie series, captures the essence of modern day germ theory in his cautionary question “judge me by my size, do you?”  Though only microscopic in size, our drinking water sources contain an unassumingly powerful enemy army.  These microorganism soldiers, such as Cryptosporidium, are dangerous enough to generate widespread illness.  Yoda’s unique grammatical warning not to overlook the power in something small is spot-on and is the basis of today’s multi-barrier approach to drinking water disinfection.

To both protect public health and support economic growth, Mount Vernon invested in significant improvements to its drinking water treatment facilities – including the addition of UV disinfection and a 50 percent capacity increase to accommodate a newly revitalized ethanol production plant.  The UV system will provide targeted Crypto disinfection at levels to achieve Long Term 2 Enhanced Surface Water Treatment Rule compliance despite any future Ohio River water quality variability.

The presenter will tell the story of the Mount Vernon WTP improvement process including: key decisions on disinfection, how new processes complement existing equipment and operations and small-site challenges.  The audience will leave with practical ideas on how these lessons-learned can apply to their own systems.

Speaker Bio

Chuck Gray is the Mount Vernon Water Superintendent.  He has 14 years of operational experience and was awarded the B.E.L.L. Award in Washington DC in 2011.   He is best known for his “MacGuyver” skills in finding innovative and unusual solutions to problems.  In his spare time, he likes to build replica movie props and is an active member of the 501st Legion, a Star Wars costuming group that helps raise money for children’s charities.

Now That’s ImPRESSive! Bedford’s Residuals Handling Innovations

Speaker                                 Eric Flinn, City of Bedford Water Superintendent

Co-Authors                           Catherine Pallotta, Senior Project Engineer at Lochmueller Group

In a world where we’re pressured to squeeze every last drop out of our investments, the City of Bedford decided to take that challenge literally.  Simultaneously meeting scores of EPA-driven drinking water standards is complex, but so is figuring out how to manage all the particulates removed through a WTP!  Bedford Utilities considered its options and ultimately selected mechanical dewatering.

When the belt filter press was first installed, the backwash holding tank fed the press directly and the resultant waste stream discharged to the sewer.  However, this disrupted the wastewater treatment plant’s biological processes and a new approach was needed.

As the saying goes, “necessity is the mother of invention.”  To address the problem, the WTP superintendent commissioned the custom fabrication of a dumpster tank to further process the press waste stream and to enable recycling back to the holding tank.  This home-grown invention brought balance back to the wastewater treatment plant; reduced disposal costs; and exceeded dewatering expectations, squeezing every last drop out to produce a cake with 36% solids content.

The presenter will walk the audience through this case study where an operator’s practical innovations led to successful process improvement: optimization of the residuals handling operation.
