| Summary: | a remote video recording system. Train speed, warning time active highway-railroad grade crossings are likely one of the an arrival-specific approach. These approaches investigated arrival, respectively. It was found that the frequency of by a given highway-railroad grade crossing. It also was constant or fixed-distance warning time devices). Violations delays and delays due to the gate arms remaining down for an device type (constant versus fixed-distance), and adequacy of during a 24hour period. It was recommended that a similar exclusively a function of the exposure. Train speed and highway-railroad grade crossings. Data was collected using influenced violations occurring after the gates were fully lanes, false activations, number of tracks, warning time length, impedance, exposure, AADT per lane, number of highway lowered, but before the train arrived. Variables that also main contributors to many of the accidents that occur at modeling procedure be used as a surrogate to accident Motorists deciding to drive around lowered gates at gated multiple tracks and/or average train speeds below 35 km/hr. occurred only on rare occasions. It appeared that violations occurring after the train passed through the crossing of this type were influenced by longer than average train operational characteristics that exist at gated active prediction models to estimate the degree of hazard presented recommended that constant warning time devices be used relationships between these violations and the geometric and sight distance were the variables investigated in this study. significantly impacted the frequency and likelihood of this specific conditions present during each train-vehicle The data was analyzed using both a site-specific approach and the influence of average site characteristics and the these crossings. The objective of this study was to develop tracks, and the variability in warning time (the presence of type of violation included false activations, number of violations before the gates were fully lowered is almost warning time length were found to be the variables that most were developed to predict the number of violations expected whenever feasible with priority given to crossings with |
