32. 32 Lessons From Developing an Archived Data User Service: Who Is Using It? Some Success Stories The incident reports provided within PORTAL are designed to give traffic operations mangers the tools to examine how their assignment of incident response resources matches the incident rates in the field. For example the automated incident report provides the average number of ongoing incidents by time of day which can be compared to the number of response personnel. PORTAL is also a tool for evaluating the ramp metering system (currently 138 ramps are metered using a systemwide adaptive control system), and by providing easy access to ramp counts and mainline speeds, ODOT has used PORTAL to assist in management of the ramp metering system. ODOT also uses PORTAL to improve its use of the loop detectors to estimate freeway travel times. Finally, the FHWA, ODOT and Metro (the regional planning organization) are using PORTAL to improve the Portland congestion management program.The incident reports provided within PORTAL are designed to give traffic operations mangers the tools to examine how their assignment of incident response resources matches the incident rates in the field.

Finally, the FHWA, ODOT and Metro (the regional planning organization) are using PORTAL to improve the Portland congestion management program. As show in Figure 2, PORTAL is being used to monitor freeway performance over time. Metro has developed the map shown to compare freeway speeds in May 2006 versus May 2005. As shown by the colors, on some segments speeds are higher, while on others speeds are lower. In addition, Metro and ODOT have used PORTAL to assess the impact of construction on a major freeway corridor. Figure 3 illustrates how speed on the eastbound Sunset Highway changed between 2004, when construction was active and 2005, when it was complete. Note that each speed curve follows the same basic pattern—slow during the morning peak and slightly slow during the evening peak—but that the speeds are lower in 2004 than they were in 2005.As show in Figure 2, PORTAL is being used to monitor freeway performance over time.

Portland is known for its rainy weather, and Metro has used the PORTAL system to suggest that the wet months witness more congestion than other times of the year. Figure 4 shows that the months with the highest rainfall also witness the most congestion. The total monthly rainfall is shown in columns while the occurrence of congestion (average amount of time per day when congestion is present) is illustrated by the line. The final paper will provide other specific examples provided by PORTAL survey respondents, as well as recommendations for next steps that can be extended to developers of ITS data archives in other cities.Portland is known for its rainy weather, and Metro has used the PORTAL system to suggest that the wet months witness more congestion than other times of the year.
