Addressing Bicyclist Safety through the Development of Crash Modification Factors for Bikeway Facilities

According to TxDOT's Crash Record Information System (CRIS) database, there have been 26,148 crashes involving bicyclists (pedalcyclists) from 2010 to 2018 in Texas, resulting in 2,885 fatalities and suspected serious injuries (KA), and 22,937 non-incapacitating and possible injuries (BC). Overall, bicycle crashes as well as fatal and suspected serious injury crashes involving bicyclists have been on the rise. This trend could continue increasing partly due to the increasing demographics of millennials and the active population in major metroplex areas and energy sector corridor. Bicyclist safety concerns exist not only in cities and metropolitan areas but for the overall state highway network as well. On-system highways are usually in better condition than local roads in terms of riding surface, shoulder presence, driveway spacing, etc. hence more bicyclists use these roadways for training, recreational, and even commuting purposes. This shift, on the other hand, has very daunting safety implications; it is estimated that 33% of all bicyclist fatalities occur on state highways. In this project, the research team will develop crash reduction factors for bikeway facilities implemented on Texas roadways to assess their safety and economic effectiveness. Bikeway facilities include but are not limited to bike lanes, buffered bike lanes, advisory bike lanes, through bike lanes, sharrows (shared bike lanes), two-way cycle tracks, protected bike lanes and so on. This research will address the development of crash reduction factors for target crash types where sufficient bicycle facility information and crash information is available. To enable future cost-benefit assessments, the research will include an estimate of service life, installation, and maintenance costs of such facilities.
