    1920-1995 Twin Cities State Highway Network
    (2014-03-21) Chen, Wei; Levinson, David M; dlevinson@umn.edu; Levinson, David M.
    Illustrates the development of the highway network in the Twin Cities metropolitan region. GIS maps of the state highway network were created for 1920-1995 (these were not previously digitized). These were used to build Markov Chain Cellular Automata models of land use change and network growth.

    Area Based Models of New Highway Route Growth
    (American Society of Civil Engineers, 2007) Levinson, David M; Chen, Wei
    Empirical data and statistical models are used to answer the question of where new highway routes are most likely to be located. High-quality land-use, population distribution and highway network GIS data for the Twin CitiesMetropolitan Area from 1958 to 1990 are developed for this study. The highway system is classified into three levels, Interstate highways, divided highways, and secondary highways. Binary logit models estimate the new route growth probability of divided highways and secondary highways. Interstates, however,are not modeled here and are used as a predictor in modeling the growth of divided highways and secondary highways. The results show that the area's land-use attributes and population density level do have significant relationship with the area's likelihood of adding new highway routes.

    Paving New Ground
    (Elsevier, 2005) Levinson, David M; Chen, Wei
    This paper explores the inter-connectedness and co-evolution of transportation networks and land use through the application of a Markov Chain model to the Twin Cities from 1958 through 1990. This model investigates how individual cells, with both land use and transportation network attributes, change over time. Cells with more transportation network available are more likely to develop, and cells that are developed are more likely to attract additional highway investment.

    Traffic Management Systems
    (Kluwer Academic Publishers, 2004) Levinson, David M; Chen, Wei
    This study uses regression analysis to evaluate long-run traffic management system performance. Three important traffic management systems in the Twin Cities metro area - Ramp Metering, Variable Message Signs (VMS), and Freeway Service Patrol (the Highway Helper Program) were evaluated with multiple regression models to predict link speed and incident rate. We find that ramp meters increase freeway link speed and reduce incident rate. Freeway Service Patrols increase link speed when incidents are present. The results for variable message signs are ambiguous.
