Developing a System to Identify Passing and No Passing Zone Boundaries on Rural Two-Lane Highways

Tuesday, August 16, 2016 - 18:45

MRIGlobal developed an automated system to measure and display the distance between two instrumented vehicles traveling along a road. The system uses GPS modules and radio modems to send location information between the vehicles five times per second. A field software was developed to calculate the distance between the vehicles based on this GPS data in real time and report it to the following driver. The field software is designed to allow the two vehicles to identify locations along a two-lane road where minimum passing sight distance is available. A post-processing software was also developed to produce a recommended striping plan, for both directions of travel along the route, based on the data recorded by the field data collection software. This system can be operated at near-highway speeds. The full report of the project is available at: https://library.modot.mo.gov/RDT/reports/TR201514/cmr16-017.pdf
