|a Research is being performed to integrate railroad information
|
| 520 |
|
|
|a into traffic management centers for the improvement of
|
| 520 |
|
|
|a traffic operations and safety on the surface street system.
|
| 520 |
|
|
|a An issue of major concern is the advanced warning of train
|
| 520 |
|
|
|a arrivals at highway-rail intersections. Several research
|
| 520 |
|
|
|a projects are being performed to develop new technologies for
|
| 520 |
|
|
|a gathering this information from the rail corridor and for
|
| 520 |
|
|
|a communicating it to traffic management centers. Little or no
|
| 520 |
|
|
|a research has been done to incorporate existing technologies
|
| 520 |
|
|
|a for this purpose. Lack of methods for using technologies
|
| 520 |
|
|
|a already available in the field to predict train arrivals has
|
| 520 |
|
|
|a prompted this research focusing on the development of
|
| 520 |
|
|
|a algorithms, using data obtainable from existing technologies,
|
| 520 |
|
|
|a for prediction of train arrival and clear times. A typical
|
| 520 |
|
|
|a rural-to-urban rail corridor, containing numerous at-grade
|
| 520 |
|
|
|a highway-rail intersections, was chosen for this study. Six
|
| 520 |
|
|
|a general algorithms, incorporating different types and amounts
|
| 520 |
|
|
|a of information, were developed to predict train arrival
|
| 520 |
|
|
|a times. Four algorithms for predicting intersection blockage
|
| 520 |
|
|
|a by trains were developed to be used in predicting clear
|
| 520 |
|
|
|a times. These algorithms were evaluated based on their logic,
|
| 520 |
|
|
|a ability to explain actual train movements, as well as their
|
| 520 |
|
|
|a accuracy and precision. Results indicated that predictive
|
| 520 |
|
|
|a algorithms incorporating the largest amount of information
|
| 520 |
|
|
|a yielded the most accurate results. It was found that
|
| 520 |
|
|
|a acceleration and deceleration rates of trains between the
|
| 520 |
|
|
|a rural detection intersections included in the study were not
|
| 520 |
|
|
|a useful in predicting arrival times downstream for the study
|
| 520 |
|
|
|a corridor. Train speeds at the detection intersections,
|
| 520 |
|
|
|a however, are useful in making these predictions. Comparisons
|
| 520 |
|
|
|a between the use of actual and mean historic train speeds at
|
| 520 |
|
|
|a detection intersections indicated a distinct advantage in the
|
| 520 |
|
|
|a use of actual train speeds. Comparisons between using link-
|
| 520 |
|
|
|a speed and point-speed detection methods showed an advantage
|
| 520 |
|
|
|a in precision and accuracy with the use of the point-speed
|
| 520 |
|
|
|a method. For the study corridor, it was found that the use of
|
| 520 |
|
|
|a posted train speeds in algorithms consistently led to better
|
| 520 |
|
|
|a predictions than did the use of mean historical train speeds.
