The Missouri, Illinois, Indiana and Ohio Transportation Departments formed a coalition to investigate the feasibility of adding dedicated truck lanes to I-70 through their 165-mile-long, four-state corridor.
As a subconsultant, Lochmueller Group (Lochgroup) provided specialized planning and environmental services to support the traffic and revenue forecasts, economic impact analysis, and environmental screening of the alternatives. Lochgroup’s responsibilities included:
- Review of Phase I traffic and toll revenue forecasts
- Specialized travel demand analysis to estimate the accrual of economic benefits within and beyond the four-state corridor
- Meta-analysis of available data, models, and literature to support the development of key economic impact and travel demand parameters including values of time, emission rates and costs, crash rates and costs, vehicle occupancy, trip rates, and lengths
- Environmental fatal flaws analysis for the Phase I alternatives utilizing GIS
Lochgroup’s analyses synthesized data from many sources including multiple statewide and MPO travel models, the National Household Travel Survey, GIS databases, and numerous analyses and reports in order to develop the best possible assumptions for the I-70 corridor.
