2021 Academic Transportation Research Program

Haul Road and Detour Maintenance trending idea

Designated detours and haul roads are often a part of construction projects. Policies have been developed to ensure that these roads are returned to their pre-construction condition. Also, overweight trucks can sometimes be allowed to travel on roads through MnDOT permit process. The current permit assessment is based on flat fee (ex. not based on excess damage caused by the overweight trucks). however Accurate methods... more »

Predicting traffic impacts of ridesharing trending idea

The emergence of Uber and Lyft as major travel modes has not been taken into consideration by most commercial planning models.

This model assumes private vehicle ownership and trips, i.e. vehicles start at an origin and park at a destination. After serving a passenger, ridesharing vehicles continue driving around empty, creating extra... more »

Complete Streets Speed Impacts trending idea

Complete streets concepts often change existing highway cross section to provide a more friendly environment for bicycles and pedestrians. Sometimes the desired effect is to reduce the vehicle operating speeds. This proposal is to assess the before and after operating speed of various cross sectional changes so that the impact of future changes can be estimated. Speed limits are set based on operating speeds. Clear zone... more »

Traffic Signal Indication dimming at night. trending idea

Traffic Signal indications need to be bright during the day, but they don't need to be as bight during night time hours. I think there have been studies on how much they can be dimmed and still be effective. Currently signal indications are not dimmed at all. I think the indications are too bright, causing too much glare. At night the bright/blinding indications makes it hard to see pedestrians. It is almost like someone... more »
