Target Speed - the highest operating speed at which vehicles should ideally operate on a roadway in a specific context.

Free flow conditions mean that vehicles are unimpeded by other vehicles or by traffic control devices such as traffic signals.Ĩ5th Percentile Speed - the speed at or below which 85 percent of vehicles travel. Operating Speed - the speeds at which vehicles are observed operating during free flow conditions. as useful background for understanding the nationwide shift of increasing speed limits on interstates.ĭesign Speed - the selected speed used to determine the various geometric design features of the roadway. The IIHS speed webpage provides a table of maximum statutory speed limits on interstates in each state and provides history on maximum speed limits throughout the U.S. The Insurance Institute for Highway Safety (IIHS) has conducted research on speed limits and provides a resource page on maximum and statutory speed limits in addition to resources provided on the ITE Speed Management for Safety resource hub.

Additionally, the World Road Association Road Safety Manual, A Manual For Practitioners And Decision Makers On Implementing Safe System Infrastructure and the World Resources Institute report titled Sustainable and Safe: A Vision and Guidance for Zero Road Deaths provides information on how practitioners can apply the Safe Systems approach to fatalities and offers guidance on safe speed limits appropriate for the type of road, common crash types, safety of all road users, and how to effectively use safety data to inform speed management decisions. The World Health Organization Speed Management: A Road Safety Manual for Decision-Makers and Practitioners has sections on Safe Systems and the Role of Speed. ITE published a technical brief on Reduced School Area Speed Limits and the Pedestrian and Bicycle Information Center provides a school zones resource webpage. The FHWA Office of Operations provides resources on Work Zone Speed Management from observing to managing speeds in work zones. The FHWA report Guidelines for the Use of Variable Speed Limit Systems in Wet Weather provides details on how variable speed limits can be used during wet weather conditions for roads where the operating speed exceeds the design speed and stopping distance exceeds the available sight distance. Volunteers can pass information about problem speeding locations to the NPO and VPD Traffic Unit.Transportation professionals should also consider special conditions, such as intersections, transition zones, work zones and school zones, bicycle and slow lanes, safe truck speeds, and possibly the need for variable speed limit systems when designing a road and determining speed limits.

As the drivers pass through the Speed Watch set-up they also get the instant readout of their speed, displayed on a “reader board”, and they are able to compare their actual rate of speed to the posted speed limit.

Using portable radar equipment and an electronic digital board, volunteers monitor traffic in neighbourhoods, particularly school and playground zones, and document the rates of speed at which drivers are travelling. In Vancouver, Community Policing Centres operate the Speed Watch program to raise public awareness of the actual speeds at which drivers are travelling. Speed Watch helps address traffic and speeding problems through: It is an educational program aimed at reducing incidents of speeding. Speed Watch is a partnership program between the police and ICBC.
