This research presents a step-by-step guideline for traffic data collection standards set by the Institute of Transportation Engineers (ITE) and American Association of State Highway and Transportation Officials (AASHTO). This study reviews manual and automatic methods of traffic counting and provides detailed information on traffic volume and vehicle classification studies. This research also provides a detailed analysis of the Delaware Department of Transportation (DelDOT)-TMC (Transportation Management Center) websites and compares it to selected Department of Transportation websites of other states such as Vermont, Connecticut, New Jersey, Pennsylvania, California, Texas, and Virginia. The purpose of the comparison is to analyze the data sources;user friendliness, accessibility, types of data available, presentation formats, and style for each state to determine how they compared to DelDOT-TMC. Although there were some similarities, the findings suggest that two major differences are present. The overall results revealed that DelDOT-TMC provides limited traffic and roadway weather data, and presentation formats to the public as compared to the other states. Further, a unitless variable, called the Capacity Factor (Q), has been developed within this study to represent this relative comparison. This study shows that DelDOT TMC performs well within the group of selected states and better than selected states of similar size and most selected states of larger size;where only Virginia performs better then DelDOT TMC. DelDOT TMC does not perform as we

To address the growing problem of congestion, delays, and overall traffic issues, DelDOT (Delaware Department of Transportation) established the Transportation Management Center (TMC) in 1997. DelDOT-TMC also coordinates and manages DelDOT’s response to any incident that impacts the multimodal transportation system within the state of Delaware. Among other things, DelDOT-TMC collects traffic, roadway weather, and hydrological data using over a thousand monitoring devices installed throughout the state of Delaware. After data has been obtained, DelDOT-TMC analyzes and disseminates real-time travel information to the public through DelDOT’s website (online interactive maps), smartphone application, traffic advisory radio, and social media sites such as Twitter, Facebook, YouTube, Blog, and Flickr;however, the utilization and usability of this information by the public are, for the most part, unknown. The purpose of this study is to evaluate the global responsibilities of DelDOT-TMC and assess the process that DelDOT-TMC uses to gather, process, analyze, and distribute traffic and roadway weather data to the public. The study employs a survey to assess the utilization of DelDOT-TMC’s products, i.e., DelDOT Mobile App, WTMC 1380 AM travel advisory radio, DelDOT’s public website, DelDOT’s social media, as well as the usability of the DelDOT mobile app to check DART (Delaware Authority for Regio
