Economies of scale reduced projections for MnPass managed lanes operations & maintenance costs to $50,000 per mile.

In 2005, Mn/DOT completed the MnPASS Phase 1 study identifying the next set of roadways to be considered for managed lanes. That study assumed that the first MnPASS lanes would be conversions of the…

Low cost portable roadside sensor system estimates vehicle velocity within 2 percent accuracy and provides 100 percent accuracy of vehicle classification.

The sensor consists of magnetoresistive devices that measure magnetic field. The speed of the passing vehicle is estimated by calculating the cross-correlation between longitudinally spaced sensors.…

When link travel times posted on DMS are twice as long as typical travel times, drivers begin to favor alternate routes.

METHODOLOGYResearchers used an on-line survey to collect data on drivers' opinions relative to diversion route usage when dynamic message signs (DMS) show travel times that are longer than normal.…

Capital cost estimates to implement MnPASS dynamic pricing on freeway shoulder lanes ranged from $6 million to $23 million per mile.

In 2005, MnDOT completed a Phase I study that examined the conversion of high-occupancy-vehicle (HOV) lanes to high-occupancy toll (HOT) lanes on I-394 and I-35W in the Minneapolis-St. Paul area. In…

Benefit-to-cost estimates for dynamic pricing applications on freeway shoulder lanes ranged from 1.1 to 8.2.

FINDINGSBased on estimated system impacts and projected changes in travel demand over a 20 year period benefit-to-cost ratios ranged from 1.1 to 8.2 depending on corridor design. Longer corridors…

The conversion of HOV to HOT lanes on I-394 reduced mainline crashes by 5.3 percent.

METHODOLOGYModels were used to estimate traffic with and without the improvement and the Empirical Bayes method was used to determine if crash rates decreased after the conversion. Four-year…

In the Minneapolis/St. Paul, traffic speed data collected at two interstate work zones showed that when portable traffic management systems were deployed, work zone traffic volumes increased 4 to 7 percent during peak periods.

Speed information from machine vision cameras was used to evaluate the effects of PTMS on the work zone traffic conditions. This involved assessing changes in the variability of the speeds and…

In the Minneapolis/St. Paul, a motorist survey found 61% of drivers who experienced a portable traffic management system at a work zone felt more informed about traffic conditions than at other work zones.

SURVEY FINDINGSMotorist SurveyA telephone survey was used to poll motorists and assess their reaction to the PTMS. The target survey group included drivers who passed through the I-94 work zone…
