Recommendations to reduce semi-tractor trailer incidents on Indiana's major roadways

The following analysis summarizes research and recommendations regarding the importance of safety associated with drivers utilizing Indiana’s major roadways, specifically, drivers operating semi-tractor trailers. This 34-page analysis including references, has been compiled over the course of one semester and details extensive themes related to the overall well-being of semi-tractor trailers. Based on extensive research, the following items are recommended to reduce semi-tractor trailer accidents on Indiana’s major roadways: • Install ignition interlocks on semi-tractor trailers • Implementing cable barriers is a cost-effective method to eliminate the risk of cars crossing the centerline while driving • Encourage the Indiana Department of Transportation (INDOT) and its partners to conduct research on where to place cable and steel barriers • Create speed restrictions in non-interstate highways for vehicles with a gross weight greater than 26,000 pounds (lbs.) to improve the safety of rural roadways • Increase the width of these roadways will decrease the possibility of vehicles departing the road • Create situational speed restrictions for the counties listed in the “Other Restrictions Regarding Semi-Tractor Trailers” section • Post speed limit and no passing zone signs in regular intervals with proper placement in rural areas where vehicles may attempt to pass local vehicles, including farm equipment, with limited knowledge of the architecture of the roadways • Consider advocating for rest areas to be implemented on U.S. state roads in addition to interstate roadways • Construct additional rest areas on I-69 near Petersburg, IN and on I-70 in either Vermillion or Gibson County • Expand upon the rest area in White County to resolve issues of capacity and safety The transportation infrastructure continues to be a vital instrument for the Crossroads of America. As a global center of transportation and logistics, the economy of Indiana relies heavily on freight movement (INDOT, n.d.). Freight movement will continue to aid the State of Indiana in competitive advantage compared to other states. By 2040, the expected increase of freight flow is 60 percent (INDOT, n.d.). The work behind this analysis directly supports the expansion of freight mobility while promoting Indiana as a leader in prioritizing driving safety
