PTV Vistro enables you to monitor congestion, evaluate impacts, estimate VMT
and optimize signals for large and small areas in one ﬁle.

Corridor Evaluation

Big or Small, PTV Vistro Works for All
Need to evaluate intersection performance over a wide area? PTV Vistro is easily conﬁgurable to analyze large areas as well as small. One
application is the Santa Clara County Valley Transportation Authority (VTA) in California. Over 250 signals are analyzed at regular intervals to
evaluate intersection operations and monitor congestion over time. This same network is then conﬁgurable to perform localized Transportation
Impact Analysis (TIA) and corridor studies - including signal optimization and re-timing studies, without the need to start over from scratch.
Multimodal Evaluation
Analyze auto, pedestrian, and bicycle modes and the effects of transit using the HCM, the Canadian Capacity Guide, ICU, or Kimber
methods for diverse signalized, stop-controlled, and roundabout conﬁgurations. PTV Vistro reports, maps, and colorfully displays measures
of effectiveness in the network editor, making for quick screening of trafﬁc conditions and identifying locations for improvements.
Scenario Management
Model numerous existing and future conditions using PTV Vistro's powerful scenario manager. Analyze ﬂuctuations during different times of
day, varying trafﬁc levels for historic and projected growth, roadway conﬁguration changes, and signal timing modiﬁcations - including
optimized conditions. Moreover, PTV Vistro's scenario manager enables alternative comparisons and sensitivity testing, all within a single ﬁle.
Transportation Impact Analysis
Make quick work of analyzing various project scenarios with PTV Vistro's integrated TIA tools. Trip generation calculations can reﬂect
standard and custom rates. Distribution and assignment of trips are completely under the analyst's control, allowing for maximum
ﬂexibility for assignments throughout the network, including project driveways. Adjust for internal trip capture, pass-by, and diverted
trips. Want to know how much VMT project trips add, or how VMT differs between scenarios? PTV Vistro's detailed trip assignment table
calculates VMT for new project trips. Quickly test different mitigation measures using PTV Vistro's mitigation tool.
Trafﬁc Signal Optimization
Optimize signal timings along ﬂexible travel routes. PTV Vistro's robust signal optimization provides options for adjusting how delay
and number of stops affect performance evaluation, as well as the ability to allocate different weights to routes within the network.
Optimize cycles, splits, offsets, and lead/lag with PTV Vistro's robust genetic algorithm or hill climbing option.
Simulation Compatibility
Need to simulate complex conditions to further evaluate trafﬁc operations?
PTV Vistro provides a built-in simulation previewer as well as the option to export to our PTV Vissim microsimulation software.
