A Web-based Gis System for Ramp Signaling Evaluation
نویسندگان
چکیده
This study attempts to develop a Geographic Information System (GIS) based system utilized in identifying ramp site that can potentially benefit from ramp signaling. To achieve this, this paper first identifies and evaluates existing ramp signaling guidelines, and then establishes a set of warrants with consideration for their appropriateness and the availability of the required data. A web GIS system is developed that integrates data required for ramp signaling justification from various databases that currently exist and operate independently. The established warrants are included in the system to ease the analysis. The interface and functions of the system are described in this paper, followed by a case study from a set of ramps along a segment of I-95 in Miami-Dade County in Florida.
