Installations of signal countdown timers (SCTs) adjacent to the traffic signal heads are on the rise at several intersection locations in India. These SCTs provide information related to the time left for a particular signal phase and thus expected to help the driver take better decision. But no scientific studies were carried out before their installations at intersection locations. Pedestrian countdown timers (PCTs), which work on the same principle as SCTs found to be effective in terms of… 

Analysis of the Impact of Countdown Signal Timers on Driving Behavior and Road Safety

This article describes the safety and effectiveness issues related to signal countdown timers (SCT). These devices are used in many countries around the world. The impact of these devices on road

Analysis of Crossing Behavior and Violations of Electric Bikers at Signalized Intersections

This paper focuses on investigating electric bikers’ (e-bikers) crossing behavior and violations based on survey data of 3,126 e-bikers collected at signalized intersections in Nantong, China. We

Impact of Signal Timing Information on Safety and Efficiency of Signalized Intersections

The present study is an attempt to analyze the changes in queue-discharge characteristics and red-light violations (RLVs) under Indian traffic conditions due to the presence of a timer and bring to light the trade-off between safety and efficiency and the choices drivers make in the absence of phase-change information.

Evaluation of Pedestrian and Driver Behaviors at Countdown Pedestrian Signals in Peoria, Illinois

The results of the study indicate that Countdown pedestrian signals are effective in enhancing pedestrian safety and no evidence of increased risk-taking behavior of motorists while they were traversing the intersections with countdown pedestrian signals was observed.

The Effect of Digital Count-Down Display on Signalized Junction Performance

The study suggests that countdown timer has got little effect on initial delay but the effect on headway is significant and the violation of traffic light by the drivers for countdown and normal signal is compared.

Acceptability of Countdown Signals at an Urban Signalized Intersection and their Influence on Drivers Behaviour

The research presented in this paper explored how a countdown signal affects the driver’s reaction and focused on the analysis of red/amber, red and amber running violations.

Impact of Countdown Pedestrian Signals on Pedestrian Behavior and Perception of Intersection Safety in the District of Columbia

There was no overwhelming consensus of statistically significant changes in pedestrian behaviors at the intersections as a result of the CPS installations, and the results did not indicate any adverse pedestrian behavior caused by CPS installations.

AN EVALUATION OF THE EFFECTIVENESS OF PEDESTRIAN COUNTDOWN SIGNALS

Pedestrian countdown signals are being increasingly deployed in urban areas to enhance pedestrian safety at signalized intersections. However, the literature documents few efforts to evaluate their

Nebraska Transportation Center Report # UNL : SPR-P 1 ( 09 ) P 332 Final Report THE EFFECTS OF PEDESTRIAN COUNTDOWN TIMERS ON SAFETY AND EFFICIENCY OF OPERATIONS AT SIGNALIZED INTERSECTIONS

Pedestrian countdown timers were found to increase pedestrian walking speed by 0.2 ft/sec, and decrease the probability of pedestrian violations, and impact of PCT on driver safety and efficiency was not found to be statistically significant at 95% level of confidence.
