• Abstract:
  This study focused on the impact of access management practices to the safety of pedestrians. Some ; of the access management practices considered to impact pedestrian safety included limiting direct ; access to and from major streets, locating signals, limiting the number of conflict points and ; separating conflict areas, removing turning vehicles from through traffic lanes, using nontraversable ; medians to manage left-turn movements and providing a supporting street and circulation system. ; The study evaluated through statistical modeling the correlation between access management ; practices to pedestrian crashes. Focused on the impacts of access management on pedestrian crashes, ; eight (8) major roadway corridors were selected and utilized for analysis. Utilizing Negative ; Binomial, the correlation between roadway features and pedestrian crashes were modeled. Four ; variables including AADT, access density, percentage of trucks and the presence of TWLT were ; found to be positively associated with the pedestrian crash frequency. Variables such as the presence ; of median, presence of crosswalk, presence of shoulders, presence of sidewalk and high speed limit ; had negative coefficients hence their increase or presence tends to decrease pedestrian crashes. It ; could therefore be concluded that though these variables had some influence on the pedestrian ; crashes, access density, crosswalk, sidewalk and speed limit were the most statistically significant ; variables that determined the frequency of the pedestrian crashes.
